Sony Walkman NWZ-B173 review


A slight return from the former king of portable music

Very portable ; Quick charge ; Good sound quality ; Cheap price ; Built-in USB

Not the easiest to navigate ; Zap mode is annoying

Sony NWZ-B173


A ciggie lighter-sized MP3 player with 4GB of internal memory and just 27g of weight.

Fast charging ; Light ; Decent design

Non-expandable memory ; No radio ; Occasionally tricky nav wheel

4GB edition costs around the same - and can hack lossless files, has a radio and expandable memory. However, the Sony offers 10 hours more battery life off a charge - 18, rather than eight. Along with the player itself, the NWZ-B173 comes with a pair...

Sony Walkman NWZ-B173


It's been a while since I have looked at an MP3 player rather than an iPod. It is also a nice small unit that is smaller than most of course size and weight mean the display is tiny in comparison to some units but this is from Sony.

The Sony Walkman NWZ-B173 measures 8.5x2x1.3cm and it weighs just 27grams. Perhaps the biggest thing in its favour is that you can plug the USB connection (remove the cap of the unit) into a PC it is read as a drive and then you just Drag and Drop...

Sony Walkman B-series NWZ-B173 review


It's been a very long time since Walkman was the buzzword in portable audio, but Sony has refused to let it die, andkeeps polishing up elements of its range on a regular basis. This,the new B-series model, is the latest to target Apple's iPodshuffle.

Good looking, compact music player, three-minute charge time (90mins playback)

Flashing LED can be annoying, no radio

It's a well-featured player for the price, compact and easy touse. The Zappin technology seems a bit pointless, and it would havebeen nice to have an FM radio on board, but the three-minute chargeis a useful feature. If you don't want a cheap iPod,...

Average mp3 player


This mp3 player is fairly good for the money I've paid for it, £24.49 and I don't think I could have expected more for that money, but the player is really nothing special, the sound quality is poor, although it does have the extra bass button that...

Samlle, easy to handle and quick charge

Sound quality Average to Low

Sony MP3 Player < Apple iPod Shuffle


If memory is not a problem for you, then you should definitely go with Apple iPod Shuffle. And for more details about iPod, read my review on iPod Shuffle's page, with a original song sample, that could be help you to change your decision.

Average MP3 player.


My rating, 1) Sound quality : 7/10 ( Considering price, otherwise 5/10. Do not expect IPOD or BOSE.) 2) Build quality : 3/10. (Cheap poor plastic feeling. Loose head cover. SONY should go for anodized aluminium body. If we are willing to pay INR. 3800/...

Excellent music quality

Needs regular recharging

The Sony Walkman MP3 player is an amazing invention in the world of music. If you are an avid Apple fan, you will surely go for the iPod. But if you want to broaden your horizons and try something new, Sony Walkman would be ideal. I have been using the...
