well I broke down and got the pc-333D Sennhiesser set. They sound GREAT, although the ear cups are a little small, I kinda gota wiggle them to get all of my ear inside. The ear cups are smaller then the Razer Characasis set. they were a little tight on the squeeze and put pressure on my ears, but I set them over night with a plastic cup to hold them open a little more then the size of my head and now they feel great.
The USB sound card is actually very nice. it's got like a 12" cable on it, I kinda wish the USB sound card was connected to the USB plug and not have a 12" cable . The Dolby setting works great for movies and games, but with music it seems to add a little reverb.
2.0 music sounds great, all sounds are even, not over powered on the bass, or to much trebble (i tend to listen to rock, with Itunes rock eq settings).
5.1/7.1 settings for game is sweet, i was able to hear someone in COD BO or BF3 walking behind me, or outside a window to the left or right with clarity. The guns in BF3 sound AMAZING.
Software, well there really isnt any, it's just a driver and you use the sound settings in windows to set up 2.0, 4.0, 5.1 or 7.1. I just wish there was a program like creative had to set the eq for everything. instead of having to set them up in itunes, win media player.
the build quality is great, although the cable is not wrapped, it's your basic headphone cable. about 3meters long. Another thing I would have liked would be a little clip about 12" from the headset to clip it onto my shirt. The headset feels well built and more sturdy then the Razer Charcasis .
Mic, every one on vent says the mic sounds better then the Razer Charcasis. I do like the, flip the mic up and it auto mutes. I did not think I would like it at first, but it's actually easier then hitting a little switch on the cord.
Volume knob is built onto the right ear cup, just put your finger on your right ear and move one way or the other. Does not take much force, 1 finger to turn thr volume up or down.
#'s i'd give
Build Quality= 9
sound= 8 (due to the usb dolby not sounding great in music, set it at 2.0 and it's nice)
mic= 9
Comfort= 7 (untill they break in and loosen up some, and the ear cups a little small)
over all I'd give these a 8 out of 10... if your using on board sound and dont want to install a PCI or PCI-e sound card, it's def better then on board. If you have a good sound card installed, get the PC-350's or the newer PC-360.. These are Basically the PC-350 , in a new shell and package.
for $120 with free shipping, I feel these are well worth it, and def a good upgrade from on board sound and the Razer Charcasis.
