Thanks alot for all the useful info! I really appreciate it; Blast-Fax Kudos to everyone.
I decided to give the Bose a try (30 day $-back gty.). Excellent cust. svc. so far and awesome finance option. Should be here in the next couple of days.
I think that guys/gals at my airline are exposed to more noise than at other 100-friendly airlines. Almost all our lines are 8-leggers (read 8 t/o's, 8 high-speed(for the dash), low altitude descents, 8 disc/reverse events[usually have to anticipate this and have to momentarily blast the comm. so as not to miss the TWR to GND handoff]). Most of our cruising is BLO 7000'(read no FL thin air, or lower-density ATC comm). Almost all of our legs are around .5, .6 block. Our absolute longest is 1.0, maybe 1.1 block. Nobody here takes off there headsets enroute.
I've tried my Telex 5x5s with custom earmold, I've tried the hand mic/speaker mode(cruz), I've tried the 1-off 750 mode, the no-off 750 mode and the plugs & 750's mode.
What prompted me to research other headset options is that I recently tried out the foam plugs & 750's, religously, all day- after st. chklist, the plugs go in, shutdown, they come out-all day. I couldn't help but notice that it seemed like I was alot less fatigued at the end. Great, but some of our radios are not loud enough with the plugs in and I can hear myself in my head. (no, not voices). Anyway, thanks again everyone.
JParks - thanks, you answered a specific Q of mine. We have Hot-mic'ers and Not-mic'ers here. Nice to know you can still here 'em in Not-mic mode.
P.S. Huge, that link dont work.
