Thank you for viewing. Bose A20 Aviation Headset I purchased this item new. I am selling it because I no longer need it due to starting a new job. I used it carefully, so there are some minor scratches, but there are no issues with its operation. This is an essential item for those who fly piston aircraft. It protects your hearing from noise, reduces stress, and improves performance through accurate communication. Used for 1 year (approximately 100 hours) The price has increased compared to a few years ago due to the weak yen. It's a better deal than buying new, and I think it will sell for even more in a few years. Price negotiations are possible. Thank you.
