Hi there,
 
I travel between London and Hong Kong quite frequently, and currently, I'm using Monster Turbine Copper with the RSA predator and it's a good combo so far.
I used to be such an enthusiast that wanted no compromise on sound quality, so had never considered headphones with active NC feature. However, I'm a step back now, other then SQ, factors like comfy, portability can be as important. So now I'm being open mind and am wondering, in terms of noise cancellation/ isolation, how much better is active NC when comparing to IEMs? Is it worthy for me to purchase a pair of NC headphones just for travelling? If so, which pair is worthy looking at? I'm not going to set a budget yet since I've no idea of the NC headphones market...
 
It'll be perfect if some frequent flyers can share their experience here

 
Thanks!

IEM will win for isolation if we are talking a CIEM or a deep inserted like an ETY!

I usually just carry my SE215. Comfy, isolates well (with foam tips), gentle sound. Also doesn't protrude out of my ears so I can lean on my side just fine.
 
Perfect for long haul flights imo.
