For sale is a rarely used Bose A20 headset. It is in perfect working order. The controls have a small scratch on them (see photos) but are structurally intact and work like new. I don't fly anymore so I no longer need them. Please ask any questions and I will respond asap. The Bluetooth is for phone only, not the audio connection like featured on the newest models. I will ship the most economical way the buyer chooses. I would prefer to use UPS or Fedex over the USPS, but it will be the buyers choice. All original books/box/accessories included.
