Average Cost of an Xbox 360 Wireless Headset: Market-Dependent
There is no single average price because:
Many Models Exist: Official (Microsoft Wireless Headset, Bluetooth Headset) and dozens of third-party brands (Turtle Beach, Tritton, Plantronics).
Discontinued Platform: New stock is gone. Prices are entirely driven by the used/collector market (eBay, Mercari, local shops).
Condition Variance: Sealed new-in-box vs. used (working) vs. "for parts" varies wildly.
How to Find Current Value
Search **"Xbox 360 wireless headset" on eBay** → Filter "Sold Items" to see actual recent transaction prices.
Check specific model numbers (e.g., "Xbox 360 Wireless Headset" black mic boom vs. "Bluetooth Headset" silver).
Factor in: Battery health (internal rechargeable), dongle inclusion (required for non-BT models), and cosmetic condition.
Expect roughly $15–$40 USD for common used official headsets with dongles; rare/limited editions or sealed units go higher. Third-party headsets vary similarly.
