Tanga offers the refurbished Turtle Beach Ear Force PX3 Wireless Gaming Headset for $19.99 with free shipping. That's tied with our mention of a refurb from three weeks ago and $5 under the lowest total price we could find for a refurbished model today. They feature pre-installed audio presets, a built-in rechargeable battery, dynamic chat boost, and are compatible with PlayStation 4, PlayStation 3, Xbox 360, PC, and Mac.

Note: A 30-day warranty applies, although it's unclear who backs it.
