Best Buy via eBay offers the Logitech G930 7.1-Channel Surround Sound Wireless Gaming Headset, model no. 981-000257, for $69.99 with free shipping. (Jet.com and Amazon offer it for the same price.) That's $10 under our May mention, tied as the lowest total price we've seen for a new set, and a current low by $6. (For further comparison, we saw a refurb for $30 less in November.) This surround headset comes with an adjustable noise-canceling microphone, on-ear audio controls, and a mic frequency rate of 50Hz to 20kHz.
Update: Specs corrected.
