Sony has announced a dynamic duo with the W705 Walkman phone, together with the MBS-900 Bluetooth 2.1 speaker. The Walkman phone is a slider type, with WiFi, shake control, a 2.4-inch display and a 3.2-megapixel camera. It comes complete with a 4GB memory card for all your awesome music jams. The phone also can stream music via Bluetooth to either headphones or the MBS-900 speaker. The speaker has a sweet monochrome OLED display for track titles and music settings, plus has an FM radio. Any music playing is automatically muted when the phone rings. The Sony Ericsson W705 and the MBS-900 will be available in early 2009.
