Depends on what you want.
I have the Bose QC25's, and they are amazing. I travel alot, and it always blows my mind when I turn them on, and the noise cancellation makes the world go silent.
For budget headphones, I've ended up buying several of these for myself and friends/family as gifts:

I have one pair in my gym bag, and one I carry around for listening/conference calls.
Bluetooth, sound is great, battery lasts long, "hook in" style so you can work out with them and not worry about them popping out of your ear. For the price, I was blown away and they've withstood so far 9-10 months of consistent use with no issues.
