What Do I Need These For? The Hama CS-499 computer communications headset is mainly used for VoIP (Internet telephony) or use with voice recognition and voice activation computer software. The CS-499 is a stereo headphone with a high quality microphone for hands-free communication from your personal computer
That's Not All Though The head band on the Hama CS-499 is designed to fit at the back of the head. This makes it more comfortable to wear for long periods of time.
Anything Else? There is a volume switch actually on the headphone cord. The user can easily and quickly adjust the volume to a comfortable level without having to adjust the PC settings.
Frequency response - 20Hz -20 kHz, headphone impedance 32 ohms, sensitivity 108dB. 2 x 3.5mm plugs.
This is the headset we use in our office for Skype VoIP calls.
