The Clarity Aloft is superior. No batteries, ear tips last at least 100 hours (if you don't have nasty ears) Extremely light on your head for those dreadful 7 leg days. Also very nice in all GA and aerobatics (if you're into that sort of thing) I actually have CA for work and QC15 for DH and nonreving. Dont waste your money on the TSO version though.
