This transmitter works with most K (Cyber-shot) and W (Walkman) lines of Sony Ericsson phones, including the W800i, W810i, K800i and K750i. The transmitter has a key lock, microphone, belt-clip, headphone jack, and phone button, and also works as a hands-free for calls. It automatically mutes the music when you get a ring, and is available in Batman's favorite color—black. Useful if you're using your phone as your primary music player.
