Long trip ?
Cranfield to Exeter & back being a long trip just about sums up UK GA !
To return to the subject I have been in conversation with the CEO of a company that makes aircraft audio panels and intercoms one of these I am about to have fitted to my aircraft. I wanted to know what headset would work best with the companys audio system.
The reply was that lightspeed, Senhiser, Bose and most other headsets are all satisfactory and it is largely down to personal preference.
My reading of the situation is that most of the leading players in the market are using more or less the same technology for the active sound supprestion, but the comfort issue depends mostly on the shape of the individuals head so untill you have put all the options on your head you wont know the answer as to what is best for you.
I intend to be replacing my twenty year old DC's with Bose A20's as I think the comfort provided by these is likely to match the 6 hour endurance of my aircraft.
