I recently purchased one of these headsets after needing to mute my speakers so my wife could sleep without waking in the night thinking there was a tank rolling through the house....
..I must say, even though they are tight on the head and cause my jaw to get a little stiff, which is already starting to "break in" of sorts, I wouldn't give these up for anything!
As far as the review, where it was said that these lack decent bass, I must disagree. First I'm going to assume that either Razer has updated the quality of the speakers in these headsets, or the sound card used and/or it's configuration did not have "Bass Redirection" or otherwise refered to as "LFE Crossover" enabled.
I'm using this headset with a SB X-Fi Xtreme Gamer sound card, with my 'Bass Redirection' / 'Crossover Frequency' (bass cutoff frequency) set at 80Hz (as recommended to be the THX standard)...and I have to tell you my ears could never feel this much bass even at a car-audio competition in downtown Detroit!!!
I admit, at first I was very discouraged as I heard very little bass, nor could I really get a feel for any directional audio. Naturally, I had merely plugged the headset into my card and expected it to rock with no effort on my part. ~wrong~
My sound card, the mixer, and everything pertaining to my surround sound had been configured for use with my speakers (minus the bass settings, in which I had none to begin with because my wife doesn't like the house to rattle). After setting my card up for use with this headset, the quality of the bass and directional audio began to shine through like sun after a rain storm.
I can now set this headset on my desktop with volume a little over half way and turn on Independance Day (awesome sound fx)......and my headset will letteraly vibrate itself off my desk and onto my chair...all while I can almost clearly hear what is happening in the movie from across the room!
In addition, I recently disected my headset to fix a rattle I had appearantly caused by letting it dance across my desk....I noticed the cross-support 'tubes' ontop are small flattened metal bars encased in what we see as the plastic tube, and in the two weeks I've had these...they have already started to relax (thus alleviating some of that pressure on my grape).
To sum up my long-winded post, again..either Razer upgraded the quality of their speakers, or a setting was overlooked on the sound card....this headset provides some of the clearest audio I could expect from a set of headphones all while delivering above average directional audio, and bass that could rattle your fillings loose! You only have to suffer in terms of price and discomfort for several weeks (again, as in my case, until the bars start relaxing/stretching).
I hope this helps.
p.s. I think I crit myself when I got the bass figured out, I was that impressed!
