Sony Walkman NWZ-B143F: Tiny MP3 Player


Excellent audio quality and good battery life

Small form factor, built-in USB connection, easy UI navigation, voice recorder, good audio quality, good battery life, inexpensive

No built-in clip to attach to clothes, no AAC format support, UI can be a bit sluggish, bass mode reduces battery life significantly, slow data transfer speeds

Sony NWZ-B143 4GB


Straight-forward transfer for MP3s. Use of MP3 format. Attractive design. Rechargeable - ie no battery to replace. Good sound quality with solid bass, but see below.

Sound level far too low. Sufficient when used in ear-plugs, but far too low to be used with external speakers, or through the car.

Sony NWZ-B143 4GB


It can store my music (mostly wma) as well as important work documents (such as pdf, doc, ppt), battery can be charged via usb connection to computer - very useful. Has a shuffle function. Still, a very good and reliable walkman device.

Volume can be very low, even on max volume. When outdoors or on the bus with people talking it can be very difficult to hear the music. Storage also could be larger. Also the zap function is very limited (only plays a mamixum of 30 secs of a song) and...
