12 yr old Dc H10-80, gel seals, ear 'sock's, mic sock.
The only repairs - earlier this year one new speaker ~$120 fitted (dry solder) - New mic sock about two years ago ~$11.
No leaks from ear seals, no compatability probs, and beat the **** out of the co. provided Telex, particularly given years of audio abuse as an instructor, pre headset days, and then islander flying.
