Thought I'd add my two cents as mine have (after a long wait) arrived.
Initially, I was a little skeptical as they are quite big, but upon wearing them, I found them really very comfortable. I've had a quite few nights sleeping in them, and they've been great. I listened to some of the Kokoon content (which is pretty good) and used to listen to an audiobook I've been listening too.
I don't quite think the ANC is as good as my Bose, but they certainly did a decent enough job for me of blocking out other noises
Well worth the wait. I'm really happy I stuck it out in the end as these are much better than I was expecting. Really useful addition for any frequent listener to audio before bed or to relax.
Bottom Line: Yes, I would recommend this to a friend
