Most mobile phones these days also feature MP3 players, allowing you to listen to your favorite music in-between calls. With Sony Ericsson's new MH907 earbuds attached to your compatible phone, all you need do to pause the music and take a call is remove them from your ears. Put one of the buds back in your ear and start your conversation. Remove again to end the conversation, then replace both buds to start the music again. No more buttons to press, simple.
