In that $ range, I would have to go with the Sennhesier HD6XX or a pair of reburb HD600 off the Sennheiser Outlet Store. FYI: I'm a huge Sennheiser fan just to let you know. I would also have to include the very solid Fiio FT3 in that group. I'm not really a big fan of ribbons yet so I won't even try. I also own a older pair of ATH AD900x and while it's really detailed, it lacks sub bass than modern music needs to have and also can have sibilance on some recordings. If you have a bass boost option, that might not be a problem. I've never heard a pair of the R70x, but I have never seen a bad review on one. \*\*\* As always, headphones are all about personal preferrence, get a demo or a return policy if at all possible.
I have sennheiser 650 HD and audio technica ath ad900x. You can’t go wrong with either of them. I’ve had them for years
If you like FPS games, Jpop/Jrock AND especially JP/Asian female vocal, I would recommend the AD line from Audio Technica (the one I use is AD900X). AD700X more for gaming and AD900X (and above, i.e. AD1000X, AD2000X and the non-X variants) for music. The AD line is unbeatable for JP female vocal and has really great soundstage and imaging that people claim these headphones give you wall hacks. Warning that bass on these headphones are on the lower-end so you may want to demo them beforehand.
Any Audio Technica. They're super light and open. I've used my old AD900X for >4 hour sessions pretty regularly.
It was Beyerdynamic DT 440 in 2014, still have it somewhere. Before that, only headphones i had owned were some random gaming headsets. Truth be told, impressions were something like "it's clear sounding, but where's the bass?". I got used to it and afterwards listening the gaming headsets, they were just a muddy mess. Before 2015 was over, i had Audio-Technica ATH-AD900X, which again felt like an upgrade over the DT 440's. So these two i would classify as headphones that made me care about sound, if made to choose, the AD900X affected more.
Get something like an audio technica ATH-AD900x and a Mod mic to make them into a headset. Super light headphones and great soundstage.
