Single-ear USB headset for work and school
The Cyber Acoustics AC-840 is a mono headset that connects through a standard USB port and is built for offices, classrooms and call-centre desks where clear speech matters more than stereo sound. Its lightweight 3.2-ounce frame and adjustable headband suit long shifts.
Unidirectional noise-cancelling microphone
The boom-mounted mic uses active noise cancellation to reject background chatter and capture only the wearer's voice, so conference calls and voice recordings stay intelligible even in open-plan spaces. In-line volume and mute controls let users adjust levels without leaving the call.
Driver-free USB setup with ambidextrous boom
Plug the headset into any Windows, macOS or Chrome OS device and it is recognised immediately with no extra software. The flexible boom arm swings to either side for left- or right-ear wear, while the leatherette ear pad wipes clean between users. Buyers who need stereo audio or wireless freedom should look elsewhere.
