Clarity Aloft is a fantastic headset.

Simply put it is not possible for a "normal" headset to be more comfortable than the Clarity Aloft.
The band is adjustable but requires considerable force to reshape it.

The whole headset is built tough even though it looks fragile.

I used to wear it for 8 leg days in a turboprop, I wouldn't want any other.

If you're worried about TSO get the TSO'd Clarity Aloft.
