Monaural headset for voice calls

The Koss CS95 is a wired mono headset built for hands-free communication. It uses a single over-the-ear speaker so the other ear stays open to the room. A boom microphone with noise-cancelling technology reduces background sound during calls. The eight-foot cord and mini-phone connector provide a direct wired link.

Suited for single-ear monitoring

This model fits users who need to hear their surroundings while speaking, such as dispatchers, receptionists or home-office workers. The mono design leaves one ear uncovered for ambient awareness. Buyers who want stereo audio for music, gaming or immersive media should consider a dual-ear headset instead.

Frequency response 30 Hz to 16 kHz

The speaker reproduces frequencies from 30 Hz up to 16 kHz, covering the vocal range used in telephone and VoIP applications. This spec confirms the headset is tuned for speech clarity rather than full-range music playback. Check that your device accepts a mini-phone plug before purchasing.

Questions about this item

Does the mini-phone connector carry stereo sound or only mono?

The mini-phone plug delivers stereo output to the single earpiece, so both channels are mixed into one ear.

Will the over-the-head band fit a small adult head without slipping?

The adjustable over-the-head band slides to fit most adult heads and stays in place during normal use.

How do I position the boom microphone so callers hear me clearly?

Swing the boom down until the mic sits about two centimetres from the corner of your mouth; pointing it at your chin muffles the voice.
