USB VoIP Communication Headset
INSTALLATION GUIDE & USER MANUAL.
Thank you for purchasing the Accutone USB400 VoIP Communication
Headset. This high-performance headset is designed for professional Voice
over IP communication, whether it be Skype chat or any proprietary
softwares. Although the USB400 is tailor-made for human voice applications,
its 40mm custom-designed stereo speakers are more than capable of handling
top notch hi-fi gaming as well as listening to music with your PC. Aside from
perfect sound reception, it is also equipped with Accutone 's noise cancelling
microphone. On top of all that, we have reduced the size of the USB module,
added the control interface while still fitting it into a compact and stylish
casing, giving you digital audio control without compromising convenience.
Now please spend a few moments to read through this user manual before
connecting the USB headset to your computer. After familiarizing with the
features and functions, you will surely appreciate the top audio performance
this unique device offers you.
