Mic on the DC10-30 is poor, it's a false economy. You can get electret mic conversions but not cheap. The airline I work for supplied 10-30s but sent out conversion kits after a while, now supplies 13.4s.
Best bet is a DC13.4, (robust, good quality) then send it to anrman.co.uk for a noise cancelling upgrade (around £200). Advantage is you get good passive noise cancelling and additional active - very effective in GA aircraft. Bose etc. all very well but passive noise cancelling is poor so high frequencies (wind noise etc) not really addressed. Even without the conversion the 13.4s are good, but very good with. Peltors OK but not as robust, and no ANR option as far as I know.
