Hi,
I would highly recommend Sennheiser HME110. Very nice and comfortable headset, and will last for many many years. I have used it trough out my ppl training and hour building and after trying some David Clarke's, I would prefer Sennheiser's. The build quality is just second to none.

I have since upgraded to Bose A20,
Happy flying
