Introducing the NEW UHP336 inEar Earphones from Altec Lansing....THE UPGRADER SERIES HEADPHONES! New MP3 players and other portable digital devices all come with headphones. The problem is, their quality may be an afterthought. After all, device manufacturers are into devices, not headphones. Thats why Altec Lansing developed the Upgrader series of headphones to give consumers a step up when replacing headphones. All Upgrader series headphone models are designed to offer great sound. But more than that, they provide a better, more customized fit for exceptional comfort. Audio technology by Ultimate Ears.
