I used to hate everything that was Beats by Dre and railed against every headphone they made. The new studio was quite surprising actually. Haha. I think I would have bought one if they didn't have a battery inside. This aspect bugs me. If they had a passive version without NC and a battery then I might buy one. I'm serious. Haha. But in your case the NC would help with the plane ride, so it might work out.
I say go try them out to see what the heck I'm talking about.
If it's NC one is after, I'd recommend the Bose QC20s...now that is noise cancelling!
The new Beats are indeed better, but they lack some of the transparency, clarity and detail that some of the better headphones on this thread have.
