The Motorola S305's are some of the best Bluetooth headphones I've ever owned and they're usually ~$20-25. Comfortable, good battery life, decent enough audio quality, build quality that lasted 3 years. After that time the foam pads started falling apart, so I ordered another pair a few weeks ago.
There are other similar models around the same price. You don't have to spend $100+ to get similar audio quality to $20 headphones that happen to have Bluetooth as well. Bluetooth chips are stupid cheap these days, pairing that with a small battery really doesn't add much to the cost of normal cheap headphone equipment and you'll find plenty of pairs <$40.
