I have been looking for new headphones for some time and I can't really decide. My budget is $200 or less. I have narrowed my choice mostly down to Audio-Technica ATH-M50. Any recommendations on other headphones? I have looked at a few others, mostly some of the Sennheiser headphones. Also the Audio-Technica ATH-M50 came out quite a few years ago so I don't know if that should worry me? Or if there are any promising headphones coming out in the near future I should wait for.
