Sony MDR-IF240RK
$60.00
Released June, 2003
The Pros:Wireless infrared system won't interfere with any other wireless devices. Battery life is exemplary on a single AA battery. Uses an included rechargeable cell but works with regular AA batteries for non-stop listening.
The Cons:Flat ear cushions are pretty bad at keeping the headphones on your head even with a slight tilt. Headband lacks padding and is flimsy. Sound quality isn't very good for music use.
