I own the tiamat 2.2
Very uncomfortable with specs(maybe all headphones have this issue?) and a bit tight even after using it everyday for 1.5 yrs already. Top of the head gets painful after long usage too.
Got it during razer 50% if not it is overpriced imo. Sound is towards the bassy side, feels muffled when you hav been listening to good speakers and change to headphones immediately. mic is of average headset quality, nothing special, can be better.
