For sale is a pre-owned, fully operational B-Grade Bose QuietComfort 35 II Wireless Noise Cancelling Gaming Headset finished in stealth Black, model classification 852061-0010. Bench testing metrics and system diagnostic verification parameters track as follows:

• Acoustic Logic & System Integrity: The underlying dynamic driver elements are 100% operational. Diagnostics register flat, authentic audio levels across both left and right speaker modules with zero distortion or tracking balance offset errors. Bose's signature multi-tier Active Noise Cancellation blocks external noise loops seamlessly. Integrated Bluetooth pairing arrays sync cleanly to computers, mobile devices, and console controllers, and the built-in internal ear-cup microphones capture crisp voice profiles for everyday telephone use.
• Detachable Boom Mic & Case Deficit: Please review carefully—this is the **Gaming Variant** of the QC35 II, but **the detachable rigid gaming boom microphone attachment and the factory zippered storage case are completely missing**. This means you cannot use the external boom mic for gaming broadcast lines unless you supply your own replacement accessory module. The headset can still be used perfectly via standard Bluetooth for audio, phone calls, and media layout tasks.
• Tested Cables Included: Included with the item is one small USB charging wire link and one jack connection auxiliary sound cord. We cannot guarantee these are the original stock lines supplied by Bose factories, but both have been verified safe and perform cleanly under electrical input loops.
• B-Grade Cosmetic Marks: The physical chassis frame registers a conservative B-Grade rating from regular field duty. Expect normal micro-scratches along the ear-cup plates, slight polishing wear tracks across high-touch margins, and light cosmetic signs of handling. The memory foam ear cushions and synthetic headband liners are soft, properly sealed, and clean.
• Sanitization Protocol: The full assembly shell, inner speaker linings, mesh sound filters, and button nodes have been blown clear, sanitized with surface-safe electronics compound wipes, and reset for instant hardware deployment.
