Query: Cyber Acoustics AC-850 Internet Communication USB Stereo Headset

I use this headset for use with a voice recognition program. The headset was received well packaged and usable right out of the box. The voice quality is very well with a small button on the cord to adjust the volume. The only drawback is that the cord seems to be quite long if you are sitting at a computer using it. The cord sometimes gets tangled with the wheels on the chair but other than that I am perfectly happy with the quality and sound that it produces.
