I've decided that the coolest improvement for my ipod would be a wireless solution for the headphones... Unfortunately, all wireless headphones I've seen require you to plug in the transmitter (they're for stereos and such). I've found two suggested solutions, one more viable than the other: 1. Radio headphones. Use the arkon transmitter or something like it, and wireless radio headphones. This seems like the easiest solution, but maybe not the best quality. However, it has the plus of being able to pump the ipod music into stereos that have radio but lack audio-in. http://www.arkon.com/SF121.htm 2. Wireless headphones with transmitters, hack. It might be possible to purchase a wireless headphone system and rewire it so that the transmitter can run off of batteries. This would give me exactly what I wanted, except I'm not positive I can get it to work. Also, transmitters are bulkier than the radio transmitter. Anyone else tried or thought of wireless headphones for portable devices?
