Kingston Headset KHX-H3CL/WR HyperX Cloud Headset Black Retail

They are re-branded Takstar Pro's with a mic attachment.
 
Very good pair of headphones for the price, readily available and frequently on sale even here in Canada.
 
The bass on these is great, speaking as someone who listens to bass music mainly. Fairly decent at blocking sound. At lower volumes the bass can drown out the mids a bit if you are listening to modern music where the bass and treble is emphasized by the production. Not a big deal though.
 
Incredibly comfortable, though people with bigger ears might want to change the pads. (For me they are perfect.)
 
Microphone isn't great and has a lot of background noise but it's not a big issue if you're using it for gaming. It is also detachable, so you can use a different mic if you want.
 
Comes packaged with a bunch of great cable attachments for various purposes which is nice.
 
Build quality is solid, probably the best you can get for under $100.

This BLOWS most 'gaming' headsets away, while true its not going to worry your £150+ Sennheisers, AKG or beyerdynamics having the 'gaming' branding slapped on these are actually doing it an injustice. The Bass is quite responsive but can slightly drown out the mids,
 
Soundstage is not huge but its also not tiny like some gaming headsets.
 
Comfort and build quality is fantastic at this price, these are £65 in the UK and i think they are just as well built as the DT990's i own and just like all beyers they are very comfortable to wear.
 
Microphone is average, but thats just like any other gaming headset.
 
Although onboard audio will work with these no problem i felt they were a lot better with an amp, Much more clarity and poppy
 
I am happy enough to use these as pure music phones away from gaming.comparing them to my DT990's they are honestly not that far away, for £65 brand new you cant complain.
