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?
I forgot I did use earplugs as well.
I was not happy with the prices for either the leather or cloth helmet, but got mine from the States. It has cutouts for my DC headset and cost £50 - arrived in 4 days from California. Don't even think of buying them in the UK.....!!!
