AltaTac via eBay offers the refurbished Vizio Bluetooth Stereo Headset, model no. XVTHB100, for $29.99 with free shipping. That's the lowest total price we could find for a refurb by $3, although we saw a new unit for $3 less in March. (For further comparison, it's $18 under the lowest total price we could find for a new unit.) They feature an adjustable headband, built-in microphone, Bluetooth, and up to six hours of rechargeable battery life.

Of note no warranty information is provided.
