Having flown over 50 hours pax time, in lots of various machines, I've tried a fair few headsets, and have to agree, Dave Clarks I think are the best I've tried.
I looked around to buy one six months or so ago, and I wasn't expecting to get a DC for my 100 quid ish budget.
But I put a few "wanted" ads around the web (I recommend
www.thehangar.co.uk), and had quite a few offers. If you do the same, I'd recommend not accepting the first offer. I nearly did, but a few weeks later, I got an offer of a Dave Clark 10.80.
This is an older model of the 13.4, and I think it's just as good. It's a bit chunkier, but like people have said, DCs are very robust.
It was definately 100 quid well spent, and it's certainly a lot better than the flying club's Peltors.
The one complaint, is it can be a bit loose, especially for aeros....does anyone know of any way of easily tightening the grip they have on the head?
