I have a big head (so my wife tells me), I've been using my DC 13.4's for 15 years and they still look like new. I've never experienced any discomfort from wearing them. On a recent club trip I flew for a total of 6 hours over two days and I was fine. I don't fly often enough to warrant buying an ANR headset and so far DC have been the best all round PNR set I've used, which is why I bought one for myself.
