Fully working Bluetooth Wireless Headset w/mic, used for about 2 years. Well taken care of. Battery still decent without any complaints. Charges via USB-C. Connects via Bluetooth (or a $25 dedicated USB wireless adapter, sold separately). Works on Xbox, Android/iPhone, or any Bluetooth device/PC/Mac.

I chose this headset because it is very comfortable to wear for longer periods, has simultaneous PC/Bluetooth audio with the 2.4 GHz adapter, and has a relatively low price. Selling because I got a newer headset. The audio quality is decent, and my buddies said the mic quality was great.

Sells new for $90: https://www.xbox.com/en-US/accessories/headsets/xbox-wireless-headset

Cheapest I can find it online used (in much worse condition) is ~$50 (eBay)
