General Information
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.That's 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.
