By coincidence I looked in the Tiger Club's house magazine today and found an article in the difficulties of intercom in the "demanding environment that is the Tiger cockpit". They recommend David Clarke 10/13.4s with a cloth or leather helmet from Transair. The headsets are about £200 from Sporty's, or £270 from Pooleys. Either way a big chunk from my flying funds! Anyone had experience with this setup?
Mark, I certainly will try earplugs - I use them when teaching drums.
