Ratings & Reviews+

Cyber Acoustics Headset, Grey - AC-840 is rated NaN out of 5 by 50.
Rated 5 out of 5 by from Great Gaming Headset Haven't heard of Cyber Acoustics prior to buying this purchase, but for the amount I paid, it was worth it. It's a USB device so plug and play!! Has a volume control on the cord which I find useless since I use ventrilo. The cord length is nice and long and Im able to hook up from my USB on the rear of my desktop and still have a little bit of cord left that allows me to move freely around my desk.

Rated 5 out of 5 by from Great for At Home Work and Skype Exactly what I expected. Comfortable and sound quality was good and the boom mic is very flexible and can be put completely up and away from face if needed overall very easy to use just plug into USB port and go!! Great Buy!

Rated 5 out of 5 by from great product I bought this because my Plantronics broke. I thought since I did not pay more than $60 it would not work well. I fooled myself because it works great!!!!

Rated 5 out of 5 by from Very good headset! I was needing a headset to use for my home computer for some online classes I'm taking, and just needed one that had just the basic features, worked well, and was affordable. This Cyber Acousitcs headset does the trick for me! Maybe it's not a stereo headset, and doesn't have all the fancy bells and whistles, but it was inexpensive, and it does the job for me. I'm glad I bought it!
