BuyDig offers the Able Planet Infared Wireless Headphones, model no. IR210T, for $29.95 with free shipping. That's the lowest total price we could find by $32, although we saw them for $3 less two weeks ago. They feature a 33-foot wireless range, on-ear volume control, and frequency response of 20Hz to 20kHz.

Don't mind an open box? BuyDig also offers an open-box version for $28 with free shipping. No warranty information is provided.
