Mono headset for VoIP and calls

The Cyber Acoustics AC-840 is a USB mono headset built for internet communication. Its single-ear design keeps one ear open to the room while you take calls or join meetings. The adjustable over-the-head frame and soft leatherette ear pad fit a wide range of head sizes comfortably.

30 mm driver and noise-canceling boom

A 30 mm dynamic driver delivers clear voice reproduction for conversations. The unidirectional noise-canceling microphone reduces background sound and rotates 180 degrees to swing to either the left or right side. In-line volume and mute controls sit within easy reach for quick adjustments.

USB audio limits and single-ear coverage

USB power removes the need for separate audio jacks but ties the headset to devices with a compatible USB port. The mono earcup leaves the other ear uncovered, so the headset is not suited for stereo media playback or immersive gaming audio. Users needing two-ear coverage or analogue connectivity should consider a different model.

Questions about this item

Will the USB plug on this AC-840 headset work with the older USB-A ports on my current desktop?

The AC-840 connects through a standard USB-A plug, so it works directly with the USB-A ports found on older desktops and laptops without any adapter.

How can I confirm the noise-canceling microphone is actually reducing background noise after I plug it in?

Open your system sound settings, speak while the boom mic is near your mouth, and watch the input level rise; then tap the mute switch on the in-line control and the level should drop to zero.

Does the box include a spare leatherette ear pad or do I need to buy one separately?

The package contains the headset with one leatherette ear pad already fitted, the adjustable headband, the flexible boom arm and the in-line volume and mute control; no spare pad is included.
