Need help finding headphones

Im looking for a pair of headphones for around like 80-90$, now keep in mind I have a big head, Steelseries Siberia v2 didnt fit my head. Right now i'm looking at the Audio Technica AUD ATHAD500X, and the Sennheiser HD 518. Maybe you guys can tell me which ones are better or maybe you know of a better set of headphones!

 

 

Audio Technica ATHM40X are just $10 more.

These might be something to look into. They are rebranded HM5. You should be able to find a decent amount of reviews on the internet.
