Sony NWZ-B142F Walkman Review

Sony-B-Series-Walkman-MenuThe Sony NWZ-B142F is a Walkman in the B series range and measures 86mm x 23.6mm x 14.5mm making it quite small (about the size of a chunky flash drive). It has a small 3 line display screen that allows you to navigate around the features of the MP3 player as well as showing track details. The Sony B series Walkman has 2GB of memory to store your tracks on and also features an FM receiver to let you listen to the radio. It’s similar to a flash drive in that it has a USB connector kept inside a cap that pulls off the end of the device and once inserted in a USB port on a PC the device charges and allows music to be transferred to and from the PC.

Features of the B Series Walkman include a 5 band graphic equalizer, Bass Boost, Voice recording, power light, AVLS, repeat, shuffle and can play MP3 and WMA files (non-DRM).

The B series walkman has a battery capacity that lets it play music for 18 hours and takes just 1 hour 10 minutes to fully charge. If the Walkman battery is completely discharged and you need to go out then a quick 3 minute charge will see it play music for up to 90 minutes if you switch it to powersave mode. It’s a handy feature should you forget to charge it before leaving home.

Sony B Series Walkman

On the left side of the device there is a 3.5mm headphone connector. On the right side there is a cap that can be removed to reveal the USB connector. On the bottom side of the device is a hold switch to prevent you accidentally pressing buttons while it’s in your pocket, and on the top side of the device you will find volume up and down buttons along with a Bass boost button.

The front of the device has a Home button/back button which takes you back to the home screen. Above that is a Zap button which helps you find tracks by playing a few seconds of the middle of the track so you don’t have to look at the screen. The silver section on the front houses the Play/Pause button in the middle with the top side of the circle skipping forwards a track and the lower side skipping back a track. The controls are very basic but do exactly what they need to do.

Sony B Series Walkman Sound Quality

Sound quality was just fine on the B Series Walkman and as with any MP3 player, you just need to make sure you feed it some decent quality MP3’s and all will be good.

Sony B Series Walkman Final Thoughts

Although the B Series Walkman has a small screen and lacks the video capabilities you really need to weigh up what you will use it for. If you want to buy a Walkman for just listening to music and perhaps the radio then this is for you as it does exactly what it needs to in these areas. So overall, simple but does exactly what it needs to do… play music.

    yesterday,i brought a Sony NWZ- B142F,2GB USB player,red,but when i connected it to my computer,nothing popped? The computer said -no new drive,can anyone help me,how can i make it work?

    • You could try a different USB port perhaps. If that doesn’t work then try uninstalling your USB ports in the device manager, they will reinstall when you do a refresh. Once re-installed, test again.

      • Dipesh Solanki says

        Brother! Which version of mobo you using, if it’s old then plz upgrade the drivers, sure it’ll take the drive(sony) automatically. Also check with BIOS plug & Play settings >should be ACTIVE.

  3. Omar Mansur says

    Do following three things to get you MP3 start working.
    1. Check your computer USB ports enabled.
    2. Reset your MP3 player by inserting a needle in hole on back side of Player
    3. Connnect your Player to USB and enjoy……………

    Sony 2 GB ‘B’ series NWZ-B142F walkman is working otherwise well. Music files can be transferred to the walkman from the PC. Recording quality is good in the walkman. But the problem is that I am not being able to transfer recorded music files from the walkman to my PC. Is it not possible in the device ? Please reply to help me at the earliest.

    • there is no such thng “maha bakvass” with Sony walkman…u can’t judge it within 1 day,it is not like Ferrari it is like Rolls Royce…i m usng it frm last feb 2010 i hv no such problem or anybody said me tht it is the worse thng u purchase,i don’t even remember.
      If you talk abt sound quality go to the Apple store and listen apple i pod touch, u will understand wht is the ipod’s sound quality is less in term of BASS gives u a treble sound but sony walkman provide u a best quality sound in its range or above this…i suggest readers to purchase this item its a value for money walkman…coz “it is SONY”.

  28. Gabriela says

    The recording quality is ok, but then sometimes it does not connect properly to the computer, or disconnects in the middle of a file transfer. This has happened to me with several computers already. There is a problem with this little gadget and that makes it very unreliable.

  29. Gabriella D. says

    I have bought sony mp3 walkman model NWZ-B142F(B) 6 months before due to virus some software files were deleted and sound is not properly hearing .I have contacted SONY dealer they are telling this model software is not currenty available .Please help me in this regard and send me the software for this model if available

  33. Hi, I have a problem with my MP3 aswell, it stars has usual if I press the reset button, but it stays in the startup mode for hours ( the screen shows the text Walkman and it has the dots appearing and disapearing ).
    Ive tryed the device manager method yet it still says that its a removable disk, I then tryed to reinstall and unnistall the MP3 drivers from the device manager and it even made it worse, now the PC tries to install the device and it keeps trying and trying, the Device manager keeps refreshing every 5 seconds and the screen stays black.
    If I unconnect the MP3 the PC says that it failed to install the device…i’ve searched the Sony website for drivers on the MP3 yet theres none available for our model (nwz-b142f), ive bought the mp3 last christmas, and I dont rememeber if it came with a CD to install it…anyone know if it came with it? And if so can you upload it to a website to share like rapidshare or something? I would really apreciate it.
    Email me at [email protected]


  34. its not getting on even after pressing the reset button???when i insert it in computer ,the computer does not reads it….however,after pressing reset button and then pressing the on button it only displays walkman and followed by dots….if i lock the hold button then it displays “HOLD” and “power off”.may i know the solution plaese?????

    • I had the exact same problem with the same model… until i realised there is a little switch on the side that says “hold”. Flick this switch to the other side and it should turn on no worries.
