## Long description

The Koss CS100 is a wired communication headset designed for office and call center environments. It provides a frequency response of 30–16000 Hz and a circumaural ear coupling for full-range sound reproduction and comfortable extended wear. The headset uses a head-band wearing style and comes in beige, offering a neutral, professional appearance suited to business settings.
Advantages
The CS100 delivers clear audio with high sensitivity and reduced distortion across its stated frequency range, supporting intelligible speech and natural-sounding playback. An electret noise-cancelling microphone enables hands-free communication with improved signal transmission, while soft ear cushions provide even pressure distribution for extended use. A wired connection with independent 3.5 mm plugs separates headphone and microphone signals for straightforward compatibility with a wide range of telephony and computer audio devices.
Suitable for
Office telephony and call centre work
Voice recognition and dictation tasks
Remote meetings and VoIP calls
Computer applications and casual multimedia where wired connectivity is required
Key specifications

Ear coupling: Circumaural (over-ear)
Connectivity: Wired with independent 3.5 mm plugs for headphone and microphone
Wearing style: Head-band
Microphone: Electret noise-cancelling microphone
Product colour: Beige

How to use
Place the head-band over the top of the head so the circumaural ear cushions surround the ears comfortably. Connect the separate 3.5 mm plugs to the audio output and microphone input of your computer, telephone, or other device. Position the microphone boom near the mouth but not touching the lips to ensure clear voice pickup while minimising breath noise. Adjust the head-band and ear cups for an even, snug fit that does not exert excessive pressure during prolonged use.
Usage recommendations
For best voice clarity, use the electret noise-cancelling microphone in quiet or moderately noisy environments and keep the microphone boom 1–2 cm from the mouth. When using with devices that require a single combined audio jack, verify whether a splitter or adapter is needed to combine separate headphone and microphone plugs.
