Can't speak highly enough of ENC. You can't put a price on your hearing, but the noise fatigue factor is another matter which is not always obvious.
I have an ENC after-market kit on my DC H10-13.4s; the battery was U/S yesterday, and after a 7.3 hour flight I was absolutely knackered. I do that flight once a week and while tiring, I've never encountered fatigue like it afterwards.
I would love to buy a Bose X if I get a tax refund this year, but this thread is the first I've heard of the Sennheiser, so I'd like to learn more of that. Dogslay, your suggestion is tantalising too, anyone else used uflymike and the QC2's? It's a brilliant idea, just wonder if it's rugged enough for the aviation environment. And how does the passive noise cancellation compare with the X's, because that's half the battle.
