Multimedia Stereophone Headphones

The Koss SB40 multimedia stereophone is a wired headset built for everyday computing tasks. Dynamic elements deliver a frequency response of 20Hz-20kHz across music, video and voice applications. Soft leatherette ear cups enclose the ears to provide passive isolation from surrounding noise. An adjustable headband and durable plastic construction accommodate most head sizes for daily wear.

Suited for PC voice and casual listening

This headset serves users who need a straightforward microphone for PC voice applications and a closed-back design for private listening. The noise-reducing microphone helps reduce background interference during calls. Buyers who want wireless freedom, active noise cancellation or a detachable boom arm should look at other models. The fixed straight cord and dual-entry design also limit mobility compared to single-cable or wireless alternatives.

Stereo frequency range and closed-cup isolation

The 20Hz-20kHz range covers the full audible spectrum for stereo playback and voice clarity. Closed leatherette cups create a physical barrier that dampens external sound without electronic processing. The dynamic drivers maintain consistent output at varying volume levels. The headset runs out of headroom when users require surround-sound decoding, high-resolution audio codecs or a microphone certified for professional broadcast standards.

Questions about this item

What type of audio and microphone ports does my computer need for the Koss Sb40 headset?

The headset uses a straight, dual-entry cord with separate plugs for the headphone and microphone connections.

Will the closed ear cups and noise-cancelling microphone work well with an older sound card?

The dynamic elements cover 20Hz-20kHz and the microphone reduces background noise, so performance depends on the sound card's own quality.

How can I confirm the headset is delivering its full frequency range after plugging it in?

Play a 20Hz-20kHz sweep tone and listen for even output across the range; the microphone can be tested with a voice recorder for background noise suppression.
