FAQ

What type of audio does the AC-840 headset provide?

The Cyber Acoustics AC-840 delivers monaural (mono) audio, meaning it uses a single earpiece for sound output. This format is ideal for voice-focused applications like calls and conferences where stereo separation isn't necessary, allowing users to maintain awareness of their surroundings while listening.

How does the noise-cancelling microphone work?

The AC-840 features a unidirectional noise-cancelling boom microphone that focuses on capturing sound from directly in front of it while reducing background noise from other directions. This technology uses acoustic design and filtering to minimize ambient sounds like keyboard clicks or office chatter, ensuring your voice comes through clearly during calls.

What devices are compatible with this USB headset?

This headset is compatible with any device that has a USB port and supports USB audio, including Windows PCs, macOS computers, Chromebooks, Microsoft Surface tablets, and various USB-equipped laptops and tablets. It operates as a plug-and-play device without requiring additional drivers on most modern operating systems.

Can the boom microphone be used on either side?

Yes, the AC-840 features an ambidextrous boom arm that can be positioned on either the left or right side of the headset. This flexibility allows both left- and right-handed users to position the microphone optimally for their speaking style and comfort preferences.

What controls are available on the headset?

The headset includes an in-line remote on the cable with both volume control and a mute toggle. These controls allow you to adjust audio levels and quickly mute the microphone during calls without needing to access software settings on your connected device.

Is the AC-840 suitable for all-day wear?

Yes, with its adjustable headband, over-the-head design, and leatherette ear pads, the AC-840 is designed for comfort during extended use. The lightweight construction and padded elements reduce pressure points, making it appropriate for call center shifts, remote workdays, or long training sessions where continuous wear is required.
