The Razer Carcharias head phone has a circumaural closed can design, with an integrated microphone. They're pretty light, and the foam cushion on the head strap rests nicely on the contours of your head. The height adjusters are smoother than most headphones we've seen. After testing the microphone we agree with its forte as a communications package - the microphone quality is quite good and it does manage to pick up, primarily your voice, without much background noise. The mic is also positioned in such a way that there is no disturbance caused by breathing or puffs of breath. There is a mic on/off switch on the cable, which comes in handy.
The pads are soft, but the pressure exerted by the device is a tad too much, especially when using it for long. On using the device for more than 20 hours, at least four hours at a time, it still didn't feel comfortable. Perhaps the headphone needs a bit more breaking in until they ease up the pressure at the base of the ear.
As far as audio quality goes the whole audio spectrum seemed narrowed. They function without any distortion even at high volume. The sound is not too bassy and we can go on about the mids and highs being repressed, but hey, lets not forget this is a gaming device. They will perform decently enough for listening to tunes, but its core function is gaming. Bottom line is that this is definitely not a device for audio appreciation. What it is however, is a thorough bred and quite expensive gaming device.
