Got the Telex 8 used to have the Telex 850, both work fine on a 73 Classic and NG.
I never liked the clamping feel of the Bose and as a Audiophile, well lets just say there is a lot better than Bose home equipment.
I have found the Sennheiser to be very very good, its just not for me, the cost is better than Bose and of course Sennheiser are well respected in the music industry, now if only BeyerDynamic would make a aviation headset.
