Bought this headset brand new as a parting gift for myself the same week Independence Air shut down. Since I spent the following years doing corporate and flying for Continental - I never got to use it more than few hours and we don't wear stuff like this on the Boeings. It's in 100% perfect shape and I have the paperwork and bag it came in. These retail for $465 new online, so I'm willing to sell it at a significant discount to that to anyone who's interested. I'll pay for shipping, just make a reasonable offer. I highly recommend the luxury of using ANR.

Below is a description from a website:

The Airman ANR 500, which is made in the USA, features an all new design, and includes volume control and a panel power option! Designed for comfort and durability with stainless steel at the stress points, this well balanced headset evenly distributes weight on the head without pressure points, and weighs just 7 ounces (198 g)! The headset provides excellent active noise reduction below 1000 Hz. Foam-filled moleskin ear cushions are standard. An electret, noise cancelling microphone is mounted on a flex boom, adjustable for left or right side operation. The battery module includes the controls for power, volume, and stereo/mono operation, as well as a low battery indicator and a metal clothing clip. The battery pack accepts one 9v alkaline battery (supplied) for 50 hours typical flying time. Panel power is available as an option. The headset also comes with a flight bag for easy portability and storage.
