If you think being tethered to your music source is a drag-or for the gym rats, an equipment-snagging hazard-consider going wireless. While some wireless headphones use radio frequency (RF) or infrared (IR) technology, your best bet for convenience and portability is Bluetooth. You can stream audio to stereo Bluetooth headphones from iPads, iPhones, and Macs, and from the iPod touch and the latest iPod nano. (You can use Bluetooth headphones with other devices if you buy a Bluetooth transmitter.)
