Sony Ericsson W705
Sony's new slider W705 Walkman phone links to the web via wi-fi and the 2.1 MBS-900 speaker system by Bluetooth

Sony Ericsson's new W705 Walkman phone can link wirelessly via Bluetooth to the company's 2.1 MBS-900 home audio system.

The MBS-900 is a stereo speaker and subwoofer system with a built-in radio. Users can even listen to the radio and make a phone call at the same time, or if the phone rings the speakers will automatically mute.

And the phone's wi-fi connectivity means users can use wi-fi hotspots to stream music wirelessly to the phone, watch YouTube video clips or download their favourite songs.

The W705 has a 3.2 megapixel camera, FM radio, Google maps and a 4GB memory card to store up to 3900 songs. It comes with Sony's Clear Bass and Clear Stereo audio enhancement, and has premium headphones to deliver "a sound that has clarity and is dynamic, rich and natural".

It also includes popular Walkman features such as the music recognition application TrackID, SensMe for matching your mood to the music and Shake Control to change tracks with the flick of your hand.
