Selling my A20 that I received from the kids for Christmas. I already have 4, so this one wasn't really needed. Great headset, non Bluetooth model. Helicopter plug with 2 plug adapter, as I fly both helicopters and fixed-wing. Hasn't been registered for warranty, so the warranty will start with your registration. New from Bose $995, priced to sell now at $750 with free Priority Mail shipping. Credit Card or PayPal. Call me at 850.890.3671 or e-mail me at [email protected]. Thanks!
