Tips to reduce noise level in helmet

[Pterodactyl_imp]

I put a crack in one of the earpieces of my NC in-ears and Bose, very kindly, replaced them even though out of warranty. I don't usually push products (apart from Hubris Omni Grade) but the Bose QC20s are the "duck's nuts", and I wouldn't use anything else.

Cheers
Don't you just love the "I wouldn't use anything else". Takes me back 40 years or more to the American Housewife style advertisement .
