NEXX NF 450 MP3 player review

Flash-based MP3 players represent today's mainstream of personal audio. Their capacity is constantly growing, functionality has almost reached the maximum technologically possible, and prices are steadily decreasing. The number of models present on the market is measured in hundreds, manufacturers - in dozens. Against this background, it is very difficult to stand out, and the developers go to all sorts of tricks. Consumers will only benefit from this, almost all new models have a "zest", whether it's design, sound quality, functionality or battery life. This is the only correct approach when manufacturers have to deal with a very competitive market. With the release of the NF-450 model from NEXX, the topic of expanding the memory of players by connecting external flash memory cards, whose capacity and availability are growing at a faster pace, is being raised again. The NF-450 accepts Secure Digital and MultiMedia Card (SD and MMC) formats, these formats are the most common today and offer a good price/capacity ratio. In addition, the same cards are used in many digital cameras and various personal electronics, so a card purchased to expand the player's memory may, if necessary, be useful in another device.

The player is equipped with 128 MB to 1 GB of internal memory and supports cards up to 1 GB, which together allows you to increase the player's memory up to 2 GB. Such an opportunity is an additional trump card in the fight against hard drive-based devices, including those from NEXX itself, which are actively pushing flash players on the market. NEXX NF-450 plays MP3, WMA and ASF files, contains a built-in FM tuner, allows you to record a signal from the built-in microphone and line-in, and can also be used as an SD / MMC card reader (card reader).

Design and Body

The body of the player is made of black rubberized plastic, pleasant to the touch. A similar plastic was used in the Ericsson T68 telephone and many other personal electronics devices. The dimensions of the NF-450 are a bit large for a flash-based model, but this allows you to fit a fairly large display on it and not save space for controls. Apparently, the large size of the device is also due to the presence of a slot for flash memory cards and a built-in battery.

The quality of manufacturing, assembly and fitting of parts is at a high level, the gaps between the parts are minimal and have a uniform width, there are no defects, the body feels like a single whole in the hand.

The design of the case uses a deliberately successful combination of black and silver colors, the player looks stylish and modern. External attractiveness is added to it by a mirrored panel on the front side, hiding the display underneath.

On the left side of the player is a slot for memory cards, covered with a rubber plug in the same color as the case. Unfortunately, the plug is not fixed, so it is easy to lose it. On the other hand, if a memory card is permanently installed in the player, this does not matter. On the opposite end there is a connector for connecting a USB cable, its plug is made of transparent plastic and is fixed on the case.

The appearance of the player makes a favorable impression, it is attractive. The case is somewhat large, but it is well-assembled and made of a material that is pleasant to the touch.

Management

Player controls are concentrated on the front and two side panels. To the right of the display on the front panel is a large five-way joystick, framed by a round decorative insert. With it, you can switch between tracks, adjust the volume, navigate through the menu and select items. The relatively large size of the joystick has a positive effect on the convenience of working with it, the finger does not slip, the number of false positives is minimal. On the top side panel are the buttons for recording, placing marks A-B and switching the equalizer. The size of the buttons is not chosen very well, they are frankly too small. This fact somewhat smooths out the fact that the buttons protrude slightly above the surface of the case, pressing is easy to fix.

The lower side panel has a button to start and stop playback, as well as a control lock switch. The switch is quite tight, its accidental operation is almost impossible.

The ease of control of the player is at a good average level, its developers did not "reinvent the wheel" and applied proven solutions. The buttons would do well to become bigger, but, as they say, "the taste and color ...".

Display and Menu

The player has a three-color organic light-emitting diode (OLED) display. The information is displayed on a dark background, so the display has a high contrast. Unfortunately, the mirror coating impairs the view of the display in the sun, it is largely "blind". The size and resolution of the display are sufficiently balanced, the proportions between the amount of simultaneously displayed information and the convenience of reading it are observed.

In playback mode, the display shows the file name, format, bit rate, elapsed time, number of files in folder, equalizer setting, battery level, and repeat mode at the same time. In addition, there is room for a signal level indicator for two channels and an animated "music string".

The player menu has a through horizontal organization and is presented in the form of stylized tabs. It is convenient to work with the menu, all sections are displayed on the display at the same time. The settings for each operating mode are made from the corresponding section, the system settings are collected in one section. The player allows you to adjust the contrast of the display, the time of its automatic shutdown and the speed of text scrolling.

In general, the NF-450's display deserves a good rating, reading information from an inverted (light images on a dark background) OLED display is much more convenient than from a monochrome LCD display. The impression of it is somewhat spoiled only by a easily soiled silver insert.

Power and PC connection

The NF-450 is connected to a personal computer via USB. The lack of support for its high-speed version, USB 2.0, can be noted here as a drawback, which results in a relatively low data transfer rate from a computer to a player and vice versa. Be that as it may, until quite recently, such a speed satisfied everyone, and it would take only a few minutes to fill the player “to the eyeballs”. When connected to a PC, the player is recognized by the operating system as a removable storage medium, so installing drivers or additional software is not required. All operations with files are performed by standard means of the operating system.

The NF-450 uses a built-in lithium polymer battery as a power source. Claimed battery life on a single charge is 15 hours. In reality, this figure is somewhat less, but the "endurance" of the player can be considered quite decent, the charge lasts for two or three days of frequent trips. The battery is charged via USB.

NEXX players have a well-deserved reputation for sound quality, and the ND-450 lives up to it. However, one should take into account the congenital ailments of regular headphones - their sound is at an average level, but in order to unlock the full potential of the player, you need a more advanced model.

Headphones supplied with the player are made of silver plastic with chrome accents. Their distinctive features are a modern design in the form of hammers and a metal mesh speaker. When working with the player, the headphones demonstrate average sound quality: high frequencies are slightly cut and there is some lack of low frequencies, although in terms of the latter parameter they still outperform regular headphones from many other manufacturers.

On other headphones, the NF-450 delivers tight bass and a clear signal across the entire frequency range, as expected. The number of sound settings (including the SRS Wow stereo expansion technology) is enough to completely "fit" the sound to your own taste. You can adjust the equalizer by five bands, this is quite enough. “Under the auspices” of SRS, the settings of the actual SRS (stereo base extension), Trubass (bass boost, you can set a truly terrifying bass level), Focus (stereo base centering) are combined. Also, from the SRS User menu, you can select one of the presets based on connecting the player to various speakers.

The sound of the player as a whole corresponds to modern realities, sometimes it seems that the manufacturers of the "top ten" use very similar and almost equally successful chips for their products.

Recording and FM radio

The player is equipped with a line input and allows you to record audio from any source in real time. Digitization is done in WMA format, which is at least unusual - there are a lot of solutions on the market that provide on-the-fly encoding to MP3 format, including those from NEXX itself. Apparently, the choice in favor of WMA was made by the manufacturer of the audio chip installed in the NF-450, guided by reasons known only to him.

Be that as it may, WMA is in no way inferior to MP3, except for its prevalence, and many connoisseurs of digital audio find 128-bit WMA files to sound more pleasant than MP3s encoded at the same bitrate.

When recording a signal from the built-in microphone, you cannot directly select the encoding bitrate, there are only three quality levels, while the maximum bitrate is 64 kbps. This seems quite reasonable, given the source of the recording; for voice data, such a bitrate is enough for the eyes. The sensitivity of the built-in microphone is sufficient for non-professional use of the NF-450. Unprofessional use means recording lectures, reports, speeches and similar events from a distance not exceeding 6-8 meters from the speaking person. If desired, with the help of the player, you can record all kinds of interviews, the characteristics of the microphone provide good speech intelligibility.

The recording quality of the signal from the line input does not raise any claims, given the inevitable losses during recoding. In addition, encoding in WMA allows you to partially solve the problem of "smeared" high frequencies, which MP3 files with a low bitrate suffer from. The maximum bitrate of audio files recorded from line-in is 128 Kbps.

The player's FM tuner has an average sensitivity and, in general, provides approximately the same reception quality as the vast majority of tuners in devices from well-known manufacturers. Automatic search detects only the largest stations with a powerful transmitter, all the rest will have to be tuned in manually. The level of interference is often quite high, but you can still listen to the radio, especially if you choose the position of the headphone wire. Of the positive features of the NEXX NF-450 tuner, one can note the station signal strength indicator shown on the display, similar to that in cell phones.

Impressions and conclusions

NEXX NF-450 is an interesting "fish" in the sea of ​​MP3 flash players. This model has several strengths that can attract users: a flash memory card slot, an OLED display, a nice design with a mirror insert, a built-in lithium polymer battery and USB charging. Among the shortcomings, one can note the low readability of the display in the sun, as well as work with a slow USB 1.1 bus. However, in Russia, and throughout the world, a huge fleet of desktop computers and laptops is still operating with just this version of the bus. Perhaps their owners will only be happy to save a little on the support of the most modern technologies. In addition, the advantages of the NF-450 are quite capable of outweighing its some slowness.

Specifications:

File formats: MP3, WMA, ASF
Bitrate: MP3: 8-320 Kbps, WMA: 5-192 Kbps
Dimensions: 35.7 x 78.2 x 19.5 mm

Consumers will only benefit from this, almost all new models have a "zest", whether it's design, sound quality, functionality or battery life. This is the only correct approach when manufacturers have to deal with a very competitive market. With the release of the NF-450 model from NEXX, the topic of expanding the memory of players by connecting external flash memory cards, whose capacity and availability are growing at a faster pace, is being raised again. The NF-450 accepts Secure Digital and MultiMedia Card (SD and MMC) formats, these formats are the most common today and offer a good price/capacity ratio. In addition, the same cards are used in many digital cameras and various personal electronics, so a card purchased to expand the player's memory may, if necessary, be useful in another device.

The player is equipped with 128 MB to 1 GB of internal memory and supports cards up to 1 GB, which together allows you to increase the player's memory up to 2 GB. Such an opportunity is an additional trump card in the fight against hard drive-based devices, including those from NEXX itself, which are actively pushing flash players on the market. NEXX NF-450 plays MP3, WMA and ASF files, contains a built-in FM tuner, allows you to record a signal from the built-in microphone and line-in, and can also be used as an SD / MMC card reader (card reader).

Design and Body

The body of the player is made of black rubberized plastic, pleasant to the touch. A similar plastic was used in the Ericsson T68 telephone and many other personal electronics devices. The dimensions of the NF-450 are a bit large for a flash-based model, but this allows you to fit a fairly large display on it and not save space for controls. Apparently, the large size of the device is also due to the presence of a slot for flash memory cards and a built-in battery.

The quality of manufacturing, assembly and fitting of parts is at a high level, the gaps between the parts are minimal and have a uniform width, there are no defects, the body feels like a single whole in the hand.

The design of the case uses a deliberately successful combination of black and silver colors, the player looks stylish and modern. External attractiveness is added to it by a mirrored panel on the front side, hiding the display underneath.

On the left side of the player is a slot for memory cards, covered with a rubber plug in the same color as the case. Unfortunately, the plug is not fixed, so it is easy to lose it. On the other hand, if a memory card is permanently installed in the player, this does not matter. On the opposite end there is a connector for connecting a USB cable, its plug is made of transparent plastic and is fixed on the case.

The appearance of the player makes a favorable impression, it is attractive. The case is somewhat large, but it is well-assembled and made of a material that is pleasant to the touch.

Management

Player controls are concentrated on the front and two side panels. To the right of the display on the front panel is a large five-way joystick, framed by a round decorative insert. With it, you can switch between tracks, adjust the volume, navigate through the menu and select items. The relatively large size of the joystick has a positive effect on the convenience of working with it, the finger does not slip, the number of false positives is minimal. On the top side panel are the buttons for recording, placing marks A-B and switching the equalizer. The size of the buttons is not chosen very well, they are frankly too small. This fact somewhat smooths out the fact that the buttons protrude slightly above the surface of the case, pressing is easy to fix.

The bottom side panel has a button to start and stop playback, as well as a control lock switch. The switch is quite tight, its accidental operation is almost impossible.

The ease of control of the player is at a good average level, its developers did not "reinvent the wheel" and applied proven solutions. The buttons would do well to become bigger, but, as they say, "the taste and color ...".

Display and Menu

The player has a three-color organic light-emitting diode (OLED) display. The information is displayed on a dark background, so the display has a high contrast. Unfortunately, the mirror coating impairs the view of the display in the sun, it is largely "blind". The size and resolution of the display are sufficiently balanced, the proportions between the amount of simultaneously displayed information and the convenience of reading it are observed.

In playback mode, the display shows the file name, format, bit rate, elapsed time, number of files in folder, equalizer setting, battery level, and repeat mode at the same time. In addition, there is room for a signal level indicator for two channels and an animated "music string".

The player menu has a through horizontal organization and is presented in the form of stylized tabs. It is convenient to work with the menu, all sections are displayed on the display simultaneously. The settings for each operating mode are made from the corresponding section, the system settings are collected in one section. The player allows you to adjust the contrast of the display, the time of its automatic shutdown and the speed of text scrolling.

In general, the NF-450's display deserves a good rating, reading information from an inverted (light images on a dark background) OLED display is much more convenient than from a monochrome LCD display. The impression of it is somewhat spoiled only by a easily soiled silver insert.

Power and PC connection

The NF-450 is connected to a personal computer via USB. The lack of support for its high-speed version, USB 2.0, can be noted here as a drawback, which results in a relatively low data transfer rate from a computer to a player and vice versa. Be that as it may, until quite recently, such a speed satisfied everyone, and it would take only a few minutes to fill the player “to the eyeballs”. When connected to a PC, the player is recognized by the operating system as a removable storage medium, so installing drivers or additional software is not required. All operations with files are performed by standard means of the operating system.

The NF-450 uses a built-in lithium polymer battery as a power source. Claimed battery life on a single charge is 15 hours. In reality, this figure is somewhat less, but the "endurance" of the player can be considered quite decent, the charge lasts for two or three days of frequent trips. The battery is charged via USB.

NEXX players have a well-deserved reputation for sound quality, and the ND-450 lives up to it. However, one should take into account the congenital ailments of regular headphones - their sound is at an average level, but in order to unlock the full potential of the player, you need a more advanced model.

Headphones supplied with the player are made of silver plastic with black and chrome inserts. Their distinctive features are a modern design in the form of hammers and a metal mesh speaker. When working with the player, the headphones demonstrate average sound quality: high frequencies are slightly cut and there is some lack of low frequencies, although in terms of the latter parameter they still outperform regular headphones from many other manufacturers.

On other headphones, the NF-450 delivers tight bass and a clear signal across the entire frequency range, as expected. The number of sound settings (including the SRS Wow stereo expansion technology) is enough to completely "fit" the sound to your own taste. You can adjust the equalizer by five bands, this is quite enough. “Under the auspices” of SRS, the settings of the actual SRS (stereo base extension), Trubass (bass boost, you can set a truly terrifying bass level), Focus (stereo base centering) are combined. Also, from the SRS User menu, you can select one of the presets based on connecting the player to various speakers.

The sound of the player as a whole corresponds to modern realities, sometimes it seems that the manufacturers of the "top ten" use very similar and almost equally successful chips for their products.

Recording and FM radio

The player is equipped with a line input and allows you to record audio from any source in real time. Digitization is done in WMA format, which is at least unusual - there are a lot of solutions on the market that provide on-the-fly encoding to MP3 format, including those from NEXX itself. Apparently, the choice in favor of WMA was made by the manufacturer of the audio chip installed in the NF-450, guided by reasons known only to him.

Be that as it may, WMA is in no way inferior to MP3, except for its prevalence, and many connoisseurs of digital audio find 128-bit WMA files to sound more pleasant than MP3s encoded at the same bitrate.

When recording a signal from the built-in microphone, you cannot directly select the encoding bitrate, there are only three quality levels, while the maximum bitrate is 64 kbps. This seems quite reasonable, given the source of the recording; for voice data, such a bitrate is enough for the eyes. The sensitivity of the built-in microphone is sufficient for non-professional use of the NF-450. Unprofessional use means recording lectures, reports, speeches and similar events from a distance not exceeding 6-8 meters from the speaking person. If desired, with the help of the player, you can record all kinds of interviews, the characteristics of the microphone provide good speech intelligibility.

The quality of recording a signal from the line input does not raise any claims, given the inevitable losses during recoding. In addition, encoding in WMA allows you to partially solve the problem of "smeared" high frequencies, which MP3 files with a low bitrate suffer from. The maximum bitrate of audio files recorded from line-in is 128 Kbps.

The player's FM tuner has an average sensitivity and, in general, provides approximately the same reception quality as the vast majority of tuners in devices from well-known manufacturers. Automatic search detects only the largest stations with a powerful transmitter, all the rest will have to be tuned in manually. The level of interference is often quite high, but you can still listen to the radio, especially if you choose the position of the headphone wire. Of the positive features of the NEXX NF-450 tuner, one can note the station signal strength indicator shown on the display, similar to that in cell phones.

Impressions and conclusions

NEXX NF-450 is an interesting "fish" in the sea of ​​MP3 flash players. This model has several strengths that can attract users: a flash memory card slot, an OLED display, a nice design with a mirror insert, a built-in lithium polymer battery and USB charging. Among the shortcomings, one can note the low readability of the display in the sun, as well as work with a slow USB 1.1 bus. However, in Russia, and throughout the world, a huge fleet of desktop computers and laptops is still operating with just this version of the bus. Perhaps their owners will only be happy to save a little on the support of the most modern technologies. In addition, the advantages of the NF-450 are quite capable of outweighing its some slowness.
