Listen to the negative.


I hate to come across as so negative, I may sound upset over the purchase, but i am not, I am simply returning them. I am upset that anyone would manufacture such headphones, further upset that anyone would choose to sell them. My guess is they...

I honestly can not think of any pros, I tried

I am amazed by the poor quality of these headphones. I read some of the negative reviews and i used the same method many of us use, we read through the reviews to see who is a complainer and who had a unique experience ; The headphones arrived in a bag...

Cyber Acoustics AC851B USB Connector Circumaural Stereo Headset & Boom Mic

However, after getting my second one I was deeply disappointed as this second one lasted me only 3 months. In both cases the wire got damaged. This headset has a very thin wire trailing out of it, you can even see it in the picture. Because of this I...

Great Quality Headset


This is a great quality microphone for the price, anyone looking for a good bargain should get this. ALSO, this headset is INCREDIBLY endurable. Over its use I would run over the wire (accidentally) with my chair almost once per day. Every time I...

The sound is great for listening to music, gaming, whatever you're doing ; It fits snug on your head, I didn't have any issues with my ears getting sore at all ; The microphone is also great, I used it for over a year while gaming and my friends could...

Honestly no cons at all

Comfortable fit

They have a constant hum. I have to turn their volume down so much to eliminate their hum that I then can't hear any music

Windows 7 is amazing as well... boot times are so much shorter than Vista... the taskbar is much better... and overall stability is way better. I've noticed that when programs crash/freeze the OS doesn't have any trouble handling it... even fullscreen...

Works fine


Decent piece of equipment overall, cheap, and worth it.

Sound quality is great, plug-in-play, comfortable, decent product

First one I ordered arrived broken, though they sent me a free replacement. The earpieces are connected by a weak piece and will break easily

Good Headset for its price


This is one good headset for its price. Very comfortable for my head. I have been playing L4D for hours and still does a good job

Not really a con, but it digitalize my voice

Great price and great sound from the phones and the mic. Easy to configure on both XP and Vista. The Updated driver from CAs website did not work with vista though. Recommend

The updated driver from CAs website did not work with Vista. Recommend sticking with what ever driver your OS loads up
