Bose A20 Aviation Headset


The A20® Aviation Headset is engineered to be more comfortable and provide more noise reduction than any headset we’ve ever made, while still delivering the clear audio you expect from Bose. And now there are more features than ever, including: a Bluetooth® audio and communications interface; customizable audio prioritization control; intuitive “plug-and-play” operation; a high-performance microphone and an optional coil cord. And at just 340 grams (12 ounces), it’s still one of the lightest active noise cancelling headsets out there. No other headset offers this unique combination of features and benefits.

Price includes domestic shipping (within Thailand) and VAT, and constitutes the official Bose RRP. Please note that we do not sell and/or ship Bose aviation headsets outside of Thailand.
