For years during my PPL days I just took what was lying around in the club and used those, then I was given a pair of DC H10 - 13.4 as a gift. WHOW! the difference that it made to my flying, to wear a comfortable headset was unbelievable, such a small thing made a big change as I went further, I could not recommend this set any higher.
If you wear a headset on a 2hr I/R sortie and then take it off at the end without feeling pain then you have found the set that works for you!
I wouldn't ride a bike or drive a cart without my own helmet and I will not take control of a light aircraft without my own trusty DC's, what ever set you choose they will become part of you.
I have been in busy airspace in a lowly PA28 with incompatible headsets. NIGHTMARE!!!
