Belkin’s new Headphone Adapter for iPhone uses a specially shaped headphone plug that fits in iPhone’s recessed headphone port. The Headphone Adapter thereby enables virtually any pair of pre-iPhone headphones or earphones to work with iPhone’s uniquely-shaped top surface — for users of premium earphones, a superior alternative to junking your old favorites in favor of replacements. Though its central portion looks like hard plastic, it’s actually flexible, and bends with the cables you attach.
