Is it worth it to upgrade from a Corsair HS70 PRO wireless headphone?

​

I'll have some extra money next month and I'm looking on where to spend it.
I've always wanted to get a nicer headset after hearing so many bad things about gaming headsets.
I like my HS70, I've had it for almost 2 years now and it's still fully functional and the only thing that broke was the battery but that was a $20 fix, so I'm wondering if it's really worth it to upgrade to something else, Ive been looking at the following: DT770, HD 569, HE4XX, ATH-AD700, X2HR, and the Monolith M565C. I am willing to accept any suggestion. I would prefer something with good sound isolation in and out as it gets fairly loud around here. Around the 100-200 USD mark in terms of price would be ideal. Over ear would be nice as i use them for long sessions and i have glasses.
I'll plug them into my PC, I don't know if impedance would be much of a problem. My ASUS motherboard says "With two op-amps onboard you're able to pump exceptional audio to your favorite cans, with 32-600Ω-headphone impedance for great flexibility." 600 seems like a lot but i don't know too much
