Used these when working on my pilots license. Bought them brand new and they have just over 40 hours on them total. Volume can be adjusted for each ear, Bluetooth available to connect to your phone if needed, or turn off noise canceling if you want.

All the foam and covers are in excellent shape. Batteries were removed after last use so they wouldn't leak.

Comes with the headset in the pictures and a soft storage case for transport that was never used. I kept the headset in my flight bag until I moved on to another set.
