Not sure if you have already decided on what you want but I would personally stay away from anything from Heil. I have used one of their headset in a very humid environment ( 9V ) and the plastics deteriorated very quickly and became sticky.

What you need will depend on your operating conditions and it’s going to be different if you operate alone in your shack versus being sharing 2 sqm in a trailer during a VHF / UHF / SHF contest with 2 other operators sitting next to you. If you are operating in such conditions you want something that is over the ear and blocking all the outside noise. We usually rely on second air pilot headsets such as the David Clark H20-10 combo headset ( if you don’t need the mic, you can just lift the boom).

If you are going to operate from the quietness of your home ( as your choice for the Yeasu M1 would suggest), then I would simply trust one of the consumer hifi brands : Sennheiser, Sony, Bose come to mind. At the end of the end our needs as amateur radio are very limited and I would favor a light and comfortable headset I can wear for 30 hours over a contest over anything particullary fency.
