Just avoid those brands (e.g. Beats)

I don't know anyone can go wrong with Sony MDR-7506 headphones, though I will admit that there are Sennheisers that are more comfortable for extended wearing. The Sony's tend to be very warm around the ears in my experience. But they have phenomenal low end response, are reasonably priced, seen in studios around the world and fold down to nice small package when necessary.

Having said that, I think I might actually prefer my Sony noise-cancelling phones, but they cost a lot more and my recommendation is still the 7506's
