Up for auction is this Sennheiser aviation headset. They are 10 years old but were only used for about 12-18 months when my son was doing his pilot’s training. He then upgraded and these have been in storage since. As far as I am aware they work and have some minimal wear on the ear pads. I have tried to show this in the photos. They come with the original case, instructions and a cable clip to attach the main cable to clothing and reduce drag. Happy bidding/flying.
