The Bose A20 Aviation Headset is a high-quality noise-cancelling headset designed specifically for aviation professionals. With its superb clear acoustics and ergonomic design, this headset offers exceptional sound quality and comfort for long hours of use. Accessories include headset case and 5-pin XLR adapter. PLEASE NOTE - this is the general aviation dual plug battery-powered (2xAA) variant without Bluetooth but includes a 5-pin XLR adapter (purchased from pilot-usa.com). Condition is used but the headset is fully functional and has been well looked after. It does however require new ear pads (easily available online for around £20) as seen in the attached photos.
