Bose QC20 - am I too .... dumb ?

[j3gq_imp]

A while ago I written why buying Bose QuietComfort headsets. While at any speed I just feel fine without hearing protection or with simple, good earplugs, long tunnels can really be a deafening pain. Long story short I bought QC20/s, they look fine, sit and fit fine and work as expected ....
BUT no way to pull the helmet over your ears (with the QC), or put the helmet on and add the the headset next.
Helmet and Bose in any combination don't fit.

What did I miss, when I read your reports about use Bose QC/s ? Are your helmets all XXXL, your ears very big, or you found a trick ?

Feels to me like I have to offer my pretty headsets on ebay or write them off.
Thanks
