I have gigantic ears , and I confirm that DC's are far more comfortable than any others devices I tried.
I have a H10-40 since 10 years and buy a H10-13,4 for Mrs Porco in 99.
Even after 5 hours flights I feel OK with either the 10-40 or 13,4.
Another thing to consider, is the manufacturer warranty.
Supposedly 5 years with DC's, it's in fact more than that.
In 99, the mike of my 10-40 was working intermittently. I sent it back in the US, and they fix it for free ! (it was 7 years old !)
Buy what you want, but IMHO, you get what you pay for ....
