Every once in a while, you will be sitting next to someone, and you will want to share what you are listening to. But there is just no way. That's because iPods and other MP3 players only have one earphone jack input. Fortunately, Altec Lansing has solved the problem with a unique buddies feature on the MUZX Series 306 earphones that lets your friend plug in a second pair of earphones and listen to your music at the same time you do. It isn't magic, it's MUZX. And it's only available on the MUZX Series 306 earphones. Style never sounded so good.
