AKG K28NC Noise Canceling Headphones Review

Noise-canceling headphones today will not surprise anyone, manufacturers of various levels have recently stepped up their efforts in this direction. Reviews of particularly outstanding models have long appeared on the site, so it’s even boring to write about regular headphones made using similar technology and in the appropriate design. This is what I thought as I unpacked the colorful box of AKG K28NC headphones from the glorious and well-deserved company AKG. The casket in the form of a plastic blister was in no hurry to open and present its contents to the public. I confess, before taking on the already received sample, I did not really bother to delve into the characteristics of the device, being satisfied with the manufacturer's reputation, the freshness of the model and the aforementioned noise reduction trend. The stronger was my surprise when, after the removed headphones, some incomprehensible block with a clip was pulled on a thin cable. More precisely, the block is understandable, the signal processing system from the microphones is hidden in it, only it looks very unusual. And I was also surprised how compact the headphones look, is it really a battery instead of a battery?

This is what AKG ended up with. Headphones are designed for use during travel and trips, as well as wherever there is a relatively uniform tiring and annoying noise: cars, subways, trains and planes.

Structurally, the K28NC is similar to the K27i model we recently described, but there is a “small” difference - in addition to the headphones themselves, you will also have to carry an external sound processing module tightly attached (on wires, of course). Standard technology is used: the module receives a signal from miniature microphones built into the headphones and mixes antiphase noise waves into the overall signal. As a result, the noise is extinguished, only music or speech remains, in a word, what the owner of the headphones listens to in them.

Unlike large headphones with a built-in noise reduction system, which need to have a case of sufficient dimensions to fit a battery inside, the K28NC are quite tiny, since this same battery is installed in an external unit. It is clear that another kind of inconvenience arises here: having received compact on-ear headphones instead of large monitor ones, the user is forced to carry the module with him everywhere, fixing it on clothes or simply putting it in his pocket.

Body and design

The case of the headphones themselves migrated to the K28NC from the K27i model almost unchanged, only slightly changing in color. The decision as a whole is sound, because, in fact, the headphones are quite ordinary, the whole "chip" lies in the external unit. So AKG did not puzzle over the design for this model, quickly “screwing” the one that was already there. The design of the headphones still uses smooth anthracite plastic, spring steel and soft black leatherette. On the ear cups there are decorative inserts painted in black and gold with a metallic sheen in the light. The polished metal headband, the same as several other AKG consumer models, unwittingly evokes associations with the famous KOSS Porta Pro headphones, you can read a little more about this in the K27i review, a link to it is given at the end of the page. In contrast to the white-gray K27i, the anthracite color of the K28NC looks more "adult" and does not evoke the idea that the color solution is similar to popular players. This is quite fair, the design moves well meet the expectations of the audience, which is very different for these two largely similar models. Noise-canceling headphones are aimed at those who spend a lot of time in transport, for example, often fly. If you need to immediately hold important negotiations, make decisions or just show your best side upon arrival from the airport, then the “cast-iron” head from the noise of the turbines is by no means the best option here. Accordingly, K28NC are designed for people who are quite old, who like to listen to music or watch movies during the trip, and do it in such a way that the noise does not interfere with enjoying the moment. By the way, the words about the audience are not “far-fetched by me”, our editor-in-chief, Eldar Murtazin, who often flies around the world, can serve as a living example here. As far as I know, Sennheiser noise canceling headphones have served him faithfully for several years now.

The design of the headphones, on the one hand, turned out to be strict and solid, as you might expect from compact on-ear headphones. On the other hand, it is not without charm; .

The side surfaces of the ear cups, like those of the K27i, are ribbed, apparently for greater finger grip comfort, and the outer edge is 2-3 millimeters higher than the inner ribs, apparently for the same purpose.

The quality of assembly and fit of parts is good, there were no surprises here. The guiding movements of the metal headband strips are made “in the image and likeness” of KOSS Porta Pro, they work reliably and do not show a predisposition to loosening. A slight backlash is still present, but the reason for it, apparently, is not in a poor-quality assembly, but in a technical necessity so that the plates do not get stuck tightly if they happen to be slightly warped.

In places where the headphones can come into contact with the scalp, soft pads are provided, this time they are black and harmoniously fit into the appearance of the model.

In the places where the cups are attached to the headband, there are plastic hinges, and they are fixed at a slight angle for better positioning of the cups relative to the ears. This simple and visual solution is quite rare, for some reason manufacturers prefer to complicate the hinges themselves. The hinges have only one degree of freedom, the hinge (and the earpiece, respectively) moves only in a vertical plane. The horizontal freedom of the cups is provided by special plastic rods, on which the cups are actually attached to the hinges. Of course, the cup cannot be rotated around its axis, but still on the bar it rotates by about 180 degrees, which more than covers all situations that may arise during use. It is noteworthy that the restrictive positions of the headphones are made different, this is necessary so that when folded, the cups do not stick into each other, but compactly adjoin each other with ear cushions. However, as with other headphones from AKG, consumer rather than professional, this “freedom of action” seems to be no small achievement. The cup rotation technology is given its own name 3D-axis, its logo is applied to the box and accompanying "papers".As in the K27i, the booms look rather fragile, it seems that their happy owner will be treated with some care with the headphones. The inner surface of the cups is flat, with concentric holes for the passage of sound waves. You can see it if you remove the ear pads. The latter are made of soft gray leatherette and have a dual function: they provide both a certain isolation from external noise, and protect those who are nearby from the sounds from the headphones. This can help avoid conflicts on the plane, where the neighbors are “chained” to their seats for several hours.

The external module is made of smooth plastic in the same anthracite color as the headphones. It is elongated in shape, somewhat reminiscent of a remote control unit for a home heater: the same rectangular case and a round “knob” on the upper end. It is useless to describe the body of the module verbally, it is better to see it in the photo. The quality of workmanship does not cause any complaints, all panels are made smoothly and accurately, although they look very simple.

The module has two significant elements: a large on/off slide switch and a bright red LED. The first has a corrugated surface and is easily groped without looking, the second shines into the eyes of all the people you meet, making you see if not a terminator, then certainly an extraordinary person.

Ease of use, sound, noise reduction

Following the example of their AKG counterparts, as well as the Porta Pro model from KOSS, the headphones require some skill in the process of donning. Steel arches move freely relative to each other, so every time after the headphones have been removed, they strive to curl up more tightly. Accordingly, the owner, to one degree or another, but still has to push the headphones apart every time, you can’t set “your size” once and for all and calm down on this. I don’t consider this fact to be a particular drawback, but still it’s worth remembering and considering before buying, so that later it wouldn’t be “excruciatingly painful” for wasted money.

The headphones sit very tightly on the head, but there is no discomfort. It is almost impossible to accidentally shake off K28NC, you have to do it intentionally. The temples also do not rub the scalp, special pads, despite their small size, perform their function with dignity.

At first, the headphone cable seemed rather thick to me, but in fact it is of a standard thickness. Apparently, the psychological setting worked: if there is an external processing unit, then the cable must be thick. The length of the cable is more than enough to put the player in your jeans pocket and immediately reinforce the block, not to feel cramped. I think that the length of the cable is enough even for a height of 190 cm and above, since at my 175 centimeters it showed a solid margin.

If we talk about the sound quality of the headphones, then, theoretically, one could simply provide a link to the corresponding passage in the K27i review. But in the case of the K28NC, you also need to take into account the sound in the noise reduction mode, so you still get it.

The sound of the headphones is good. It's so easy. In general, on-ear headphones in my personal rankings are in third place, after high-quality plug-in and large professional-monitor-famous ones. For a long time, I just did not listen to on-ear headphones. But then I had to deal with them by occupation. So I’ve been arguing for the last two and a half years: either I’ve listened to the wrong headphones before, or progress has stepped far forward.Previously, as I recall, on-ear headphones versus good in-ear headphones are not “channels” (sorry for such a colloquial expression) in terms of bass response and overall volume level in general. But recently, I was surprised to find more than one model that can, if not “fight”, then compete on equal terms. To put it simply, the K28NC sound loud and deep. To this should be added juicy medium and soft high frequencies that do not cut the ear. I listened to the headphones mainly on Archos 204 and iPod 5G, I also connected them to the outputs of two mid-range laptops, the Rover W100 and the fresh Apple MacBook. The music used was mostly electronic, but for the sake of the experiment, we listened to some jazz and rock and roll. However, the variety of styles has not changed the positive opinion about the headphones.

Unfortunately, the barrel of honey was not without a fly in the ointment, however, a specific one. It lies, you guessed it, in the noise reduction system. The system itself works pretty well, more on that below. But there is one catch in it: if you listen to music loudly, say, at a level above 75% of what the headphones are capable of, noise reduction introduces distortions into the signal that are well audible to the ear. "Dirty" bass and high frequencies. Perhaps the sound processing system simply can not cope with a powerful signal. But the headphones should not be written off because of this - it is worth making the music a little quieter, as everything returns to normal. I fully admit that among those to whom the model is oriented, there are not very many of those who, turning on loudly the fresh live of Stanton Warriors, move briskly to the office along the third ring, simultaneously checking the operation of the “noise reduction”.

When it comes to actual noise cancellation, the headphones show a selective result. Not without reason, on the box and accompanying booklets, attention is focused on the use of headphones in transport. The oversized, noise-canceling over-ears we've tested so far dampen a little bit of outside noise, including speech and music. The product from AKG also tries in this area, but still falls short of the usual (demonstrated earlier by the tested models) level. But in transport and where there is a relatively uniform noise, K28NC demonstrate their best side. During testing, I wore headphones for several hours in the subway and during those very walks along the third ring.The noise, of course, does not disappear completely, but it is muffled very noticeably. Comparing (from memory) the noise of the spring Moscow metro with open windows and aircraft turbines when listening from a bad place in the cabin, I can generally put an equal sign between them, and the metro will be even louder. So, the headphones are quite capable of coping with this noise to the level where it does not interfere with thoughtful listening to music and further falling asleep, up to a soft landing. I almost forgot, the declared operating time from one battery is 40 hours, the complete Duracell could not be planted during the testing process. Yes, the battery format is AAA, these are also called "little fingers" or "minions".

We should also note a good complete set of the model. There is a cloth bag, despite the material of execution, it looks very decent. There is also a useful thing for long-haul flights on foreign airliners - an adapter for two 3.5 mm mono jacks. The picture is completed by a standard adapter for professional connectors with a diameter of 6.3 mm - a zealous owner will also find a use for him.

Conclusions and impressions

Headphones are comfortable to wear, the main thing is to adapt to the sliding arcs. The sound is very decent, at the level of the best samples of the genre, both from AKG itself and from other equally famous manufacturers. The noise reduction system effectively copes with traffic noise, but not with speech or music. However, the manufacturer does not mention the latter, focusing on the noise of the subway, car or plane. The system has a drawback - distortion in the signal at high volume, otherwise it makes a good, if not stunning, impression.

For those who travel a lot and at the same time like to comfortably listen to high-quality music, the K28NC is quite suitable. And the price of the headphones is not at all in the “business class” - Moscow sellers ask for about a hundred dollars for them.

The external module is made of smooth plastic in the same anthracite color as the headphones. It is elongated in shape, somewhat reminiscent of a remote control unit for a home heater: the same rectangular case and a round “knob” on the upper end. It is useless to describe the body of the module verbally, it is better to see it in the photo. The quality of workmanship does not cause any complaints, all panels are made smoothly and accurately, although they look very simple.

The module has two significant elements: a large on/off slide switch and a bright red LED. The first has a corrugated surface and is easily groped without looking, the second shines into the eyes of all the people you meet, making you see if not a terminator, then certainly an extraordinary person.

Ease of use, sound, noise reduction

Following the example of their AKG counterparts, as well as the Porta Pro model from KOSS, the headphones require some skill in the process of donning. Steel arches move freely relative to each other, so every time after the headphones have been removed, they strive to curl up more tightly. Accordingly, the owner, to one degree or another, but still has to push the headphones apart every time, you can’t set “your size” once and for all and calm down on this. I don’t consider this fact to be a particular drawback, but still it’s worth remembering and considering before buying, so that later it wouldn’t be “excruciatingly painful” for wasted money.

The headphones sit very tightly on the head, but there is no discomfort. It is almost impossible to accidentally shake off K28NC, you have to do it intentionally. The temples also do not rub the scalp, special pads, despite their small size, perform their function with dignity.

At first, the headphone cable seemed rather thick to me, but in fact it is of a standard thickness. Apparently, the psychological setting worked: if there is an external processing unit, then the cable must be thick. The length of the cable is more than enough to put the player in your jeans pocket and immediately reinforce the block, not to feel cramped. I think that the length of the cable is enough even for a height of 190 cm and above, since at my 175 centimeters it showed a solid margin.

If we talk about the sound quality of the headphones, then, theoretically, one could simply provide a link to the corresponding passage in the K27i review. But in the case of the K28NC, you also need to take into account the sound in the noise reduction mode, so you still get it.

The sound of the headphones is good. It's so easy. In general, on-ear headphones in my personal rankings are in third place, after high-quality plug-in and large professional-monitor-famous ones. For a long time, I just did not listen to on-ear headphones. But then I had to deal with them by occupation. So I’ve been arguing for the last two and a half years: either I’ve listened to the wrong headphones before, or progress has stepped far forward.Previously, as I recall, on-ear headphones versus good in-ear headphones are not “channels” (sorry for such a colloquial expression) in terms of bass response and overall volume level in general. But recently, I was surprised to find more than one model that can, if not “fight”, then compete on equal terms. To put it simply, the K28NC sound loud and deep. To this should be added juicy medium and soft high frequencies that do not cut the ear. I listened to the headphones mainly on Archos 204 and iPod 5G, I also connected them to the outputs of two mid-range laptops, the Rover W100 and the fresh Apple MacBook. The music used was mostly electronic, but for the sake of the experiment, we listened to some jazz and rock and roll. However, the variety of styles has not changed the positive opinion about the headphones.

Unfortunately, the barrel of honey was not without a fly in the ointment, however, a specific one. It lies, you guessed it, in the noise reduction system. The system itself works pretty well, more on that below. But there is one catch in it: if you listen to music loudly, say, at a level above 75% of what the headphones are capable of, noise reduction introduces distortions into the signal that are well audible to the ear. "Dirty" bass and high frequencies. Perhaps the sound processing system simply can not cope with a powerful signal. But the headphones should not be written off because of this - it is worth making the music a little quieter, as everything returns to normal. I fully admit that among those to whom the model is oriented, there are not very many of those who, turning on loudly the fresh live of Stanton Warriors, move briskly to the office along the third ring, simultaneously checking the operation of the “noise reduction”.

When it comes to actual noise cancellation, the headphones show a selective result. Not without reason, on the box and accompanying booklets, attention is focused on the use of headphones in transport. The oversized, noise-canceling over-ears we've tested so far dampen a little bit of outside noise, including speech and music. The product from AKG also tries in this area, but still falls short of the usual (demonstrated earlier by the tested models) level. But in transport and where there is a relatively uniform noise, K28NC demonstrate their best side. During testing, I wore headphones for several hours in the subway and during those very walks along the third ring.Noise, of course, does not disappear completely, but it is muffled very noticeably. Comparing (from memory) the noise of the spring Moscow metro with open windows and aircraft turbines when listening from a bad place in the cabin, I can generally put an equal sign between them, and the metro will be even louder. So, the headphones are quite capable of coping with this noise to the level where it does not interfere with thoughtful listening to music and further falling asleep, up to a soft landing. I almost forgot, the declared operating time from one battery is 40 hours, the complete Duracell could not be planted during the testing process. Yes, the battery format is AAA, these are also called "little fingers" or "minions".

We should also note a good complete set of the model. There is a cloth bag, despite the material of execution, it looks very decent. There is also a useful thing for long-haul flights on foreign airliners - an adapter for two 3.5 mm mono jacks. The picture is completed by a standard adapter for professional connectors with a diameter of 6.3 mm - a zealous owner will also find a use for him.

Conclusions and impressions

Headphones are comfortable to wear, the main thing is to adapt to the sliding arcs. The sound is very decent, at the level of the best samples of the genre, both from AKG itself and from other equally famous manufacturers. The noise reduction system effectively copes with traffic noise, but not with speech or music. However, the manufacturer does not mention the latter, focusing on the noise of the subway, car or plane. The system has a drawback - distortion in the signal at high volume, otherwise it makes a good, if not stunning, impression.

For those who travel a lot and at the same time like to comfortably listen to high-quality music, the K28NC is quite suitable. And the price of the headphones is not at all in the “business class” - Moscow sellers ask for about a hundred dollars for them.

AKG K28NC Noise Canceling Headphones Review

Noise-canceling headphones today will not surprise anyone, manufacturers of various levels have recently stepped up their efforts in this direction. Reviews of particularly outstanding models have long appeared on the site, so it’s even boring to write about regular headphones made using similar technology and in the appropriate design. This is what I thought as I unpacked the colorful box of AKG K28NC headphones from the glorious and well-deserved company AKG. The casket in the form of a plastic blister was in no hurry to open and present its contents to the public. I confess, before taking on the already received sample, I did not really bother to delve into the characteristics of the device, being satisfied with the manufacturer's reputation, the freshness of the model and the aforementioned noise reduction trend. The stronger was my surprise when, after the removed headphones, some incomprehensible block with a clip was pulled on a thin cable. More precisely, the block is understandable, the signal processing system from the microphones is hidden in it, only it looks very unusual. And I was also surprised how compact the headphones look, is it really a battery instead of a battery?

This is what AKG ended up with. Headphones are designed for use during travel and trips, as well as wherever there is a relatively uniform tiring and annoying noise: cars, subways, trains and planes.

Structurally, the K28NC is similar to the K27i model we recently described, but there is a “small” difference - in addition to the headphones themselves, you will also have to carry an external sound processing module tightly attached (on wires, of course). Standard technology is used: the module receives a signal from miniature microphones built into the headphones and mixes antiphase noise waves into the overall signal. As a result, the noise is extinguished, only music or speech remains, in a word, what the owner of the headphones listens to in them.

Unlike large headphones with a built-in noise reduction system, which need to have a case of sufficient dimensions to fit a battery inside, the K28NC are quite tiny, since this same battery is installed in an external unit. It is clear that another kind of inconvenience arises here: having received compact on-ear headphones instead of large monitor ones, the user is forced to carry the module with him everywhere, fixing it on clothes or simply putting it in his pocket.

Body and design

The case of the headphones themselves migrated to the K28NC from the K27i model almost unchanged, only slightly changing in color. The decision as a whole is sound, because, in fact, the headphones are quite ordinary, the whole "chip" lies in the external unit. So AKG did not puzzle over the design for this model, quickly “screwing” the one that was already there. The design of the headphones still uses smooth anthracite plastic, spring steel and soft black leatherette. On the ear cups there are decorative inserts painted in black and gold with a metallic sheen in the light. The polished metal headband, the same as several other AKG consumer models, unwittingly evokes associations with the famous KOSS Porta Pro headphones, you can read a little more about this in the K27i review, a link to it is given at the end of the page. In contrast to the white-gray K27i, the anthracite color of the K28NC looks more "adult" and does not evoke the idea that the color solution is similar to popular players. This is quite fair, the design moves well meet the expectations of the audience, which is very different for these two largely similar models. Noise-canceling headphones are aimed at those who spend a lot of time in transport, for example, often fly. If you need to immediately hold important negotiations, make decisions or just show your best side upon arrival from the airport, then the “cast-iron” head from the noise of the turbines is by no means the best option here. Accordingly, K28NC are designed for people who are quite old, who like to listen to music or watch movies during the trip, and do it in such a way that the noise does not interfere with enjoying the moment. By the way, the words about the audience are not “far-fetched by me”, our editor-in-chief, Eldar Murtazin, who often flies around the world, can serve as a living example here. As far as I know, Sennheiser noise canceling headphones have served him faithfully for several years now.

The design of the headphones, on the one hand, turned out to be strict and solid, as you might expect from compact on-ear headphones. On the other hand, it is not devoid of charm, the decorative inserts on the sides of the cups, dully shimmering in the light, are clearly intended for other people's interested looks.

The design of the headphones, on the one hand, turned out to be strict and solid, as you might expect from compact on-ear headphones. On the other hand, he is not without charm, dull metallic inlays on the sides of the cups are clearly intended for other people's interested looks.

The side surfaces of the ear cups, like those of the K27i, are ribbed, apparently for greater finger grip comfort, and the outer edge is 2-3 millimeters higher than the inner ribs, apparently for the same purpose.

The quality of assembly and fit of parts is good, there were no surprises here. The guiding movements of the metal headband strips are made “in the image and likeness” of KOSS Porta Pro, they work reliably and do not show a predisposition to loosening. A slight backlash is still present, but the reason for it, apparently, is not in a poor-quality assembly, but in a technical necessity so that the plates do not get stuck tightly if they happen to be slightly warped.

In places where the headphones can come into contact with the scalp, soft pads are provided, this time they are black and harmoniously fit into the appearance of the model.

In the places where the cups are attached to the headband, there are plastic hinges, and they are fixed at a slight angle for better positioning of the cups relative to the ears. This simple and visual solution is quite rare, for some reason manufacturers prefer to complicate the hinges themselves. The hinges have only one degree of freedom, the hinge (and the earpiece, respectively) moves only in a vertical plane. The horizontal freedom of the cups is provided by special plastic rods, on which the cups are actually attached to the hinges. Of course, the cup cannot be rotated around its axis, but still on the bar it rotates by about 180 degrees, which more than covers all situations that may arise during use. It is noteworthy that the restrictive positions of the headphones are made different, this is necessary so that when folded, the cups do not stick into each other, but compactly adjoin each other with ear cushions. However, as with other headphones from AKG, consumer rather than professional, this “freedom of action” seems to be no small achievement. The cup rotation technology is given its own name 3D-axis, its logo is applied to the box and accompanying "papers". As in the K27i, the booms look rather fragile, it seems that their happy owner will be treated with some care with the headphones.The inner surface of the cups is flat, with concentric holes for the passage of sound waves. You can see it if you remove the ear pads. The latter are made of soft gray leatherette and have a dual function: they provide both a certain isolation from external noise, and protect those who are nearby from the sounds from the headphones. This can help avoid conflicts on the plane, where the neighbors are “chained” to their seats for several hours.
