Weighing just 28g, new Walkman® B Series is small and light enough to take anywhere: but don’t be deceived by its tiny size. Press the Bass Boost button and you’ll be blown away by rich, pumping low-end. And to show where you’re coming from, there’s a colour-matched LED that pulses in time with the music.

When you’re in a hurry, 3 minutes charging time gives enough battery power for 90 minutes listening. Fully charged, Walkman® B Series lets you listen non-stop for 18 hours1 – plenty for the longest commute or an overnight break.

You won’t want to keep other people in the dark about your favourite MP3 player. Walkman® B Series features a chunky clip that attaches to a belt, bag strap or clothing to show off your style.

It’s easy to load up with your favourite songs. Walkman® connects directly to any Windows2 PC via its built-in USB port with no extra cables required. Copying files is a simple drag-and-drop process, with no need to install any file transfer software. You can also connect Walkman® to a compatible hi-fi or car stereo3 and enjoy direct playback.

Looking for the right song to fit your mood? ZAPPIN™ search technology scans through your music collection, previewing a snatch of each track without menus or playlists. Hear a track you like and press the ‘ZAP’ button again to hear the whole song.

Extra refinements include an on-board equalizer to sculpt your sound, plus a voice recorder that’s perfect for grabbing spontaneous thoughts, notes and ideas.

The new Walkman® B170 Series of MP3 players by Sony are available in a choice of 2GB or 4GB capacities from January 2012.
