Quiet room could use open design headphones with fabric/velour pads for best comfort.
But GSP 670 is typical gaming headset with closed design and leatherette pads, making it good for noisier places like LANs, but not that great in letting heat out.
So likely not something what could be worn comfortably for whole day at least in warmer room.
Bulk and weight is also mentioned in quite few reviews and gotta agree 400 grams likely wouldn't be that comfortable for long duration use.
For wireless part that absolutely miniscule USB dongle transceiver might be wimpy.
10 meters isn't much for advertised range and you can bet that isn't measured in hard conditions.
Rock Pager Shotgun got hiccups in sound when moving 2 meters from desktop PC to laptop, with only wooden table in line of sight.
Of course test environment might have been particularly wireless heavy with lots of stuff using 2.4GHz.
But such sensitivity isn't exactly great thing, if you want to move around when listening say music.
Sennheiser RS models with their hefty base station are advertised for up to 100m range in LOS conditions and also that's "optimistic" with safer assumption being half of that.
And if you add wall in between range drops fast...
Sound seems to be mixed bag of "slightly weakish bass to strong bass".
But of course that would require some reference to be reliable.
Anyway overall theme for those results seem to be toward stronger bass, with one mention of them being perfect for bass heavy stuff.
