Did you look on Amazon because a quick search shows Amazon selling the black version for $50 USD. So this is not much of a clearance deal if the online price is the same.
I use the Steelseries Siberia 200s in Sakura Purple. They're awesome! And they have the jacks instead of usb like you requested. Plus, you can get all sorts of different colors :D They run about $60-70 which seems a little steep compared to logitech ones (those are also legit af). I like these though because they're more comfortable than logitech to me, but that might just be me. ¯_(ツ)_/¯
what should I get then? I've got about £40 to spend on an earphone and mic set and I was going to get These because I know from experience their good earphones but your post has given me doubt
Uhh... Op, They're 39.99
Also available on Amazon for same price if you got prime
