Leave your phone in your pocket or bag and listen to the music saved on it in high quality wireless stereo. Let the Sony Ericsson HBH-DS220 handle calls without touching your phone. Hitting the treadmill? Settling down on a sunny chair in the garden? The 3.5 mm jack means you can change the headphones if you want to. Clip the lightweight pendant to your top where it can hang out of the way. The music and call handling keys remain close to hand.
