Newegg offers the refurbished Logitech G633 Artemis Spectrum Gaming Headset for $34.99 with free shipping. That's the lowest refurb price we could find by $20 and the best price we've seen for this headset in any condition. They feature 7.1 Dolby and DTS surround sound and a 100Hz to 20KHz frequency response. Note: A 90-day warranty is included, however it's unclear who backs it.
