Classroom USB stereo headset

The Cyber Acoustics AC-4006 is a wired headset designed for daily classroom use. It connects through a single USB port and requires no driver installation. A unidirectional microphone with noise-cancelling circuitry reduces background sound during lessons. Leatherette ear pads and an adjustable headband are built to withstand repeated student handling.

Suited for school deployments.

This model fits educators who need a plug-and-play solution for language labs, testing or video lessons. The rotating boom lets each user position the mic quickly. Buyers who want high-fidelity music reproduction, wireless freedom or detachable cables should look at other categories.

USB connection and 20 Hz to 20 kHz response

The headset draws power and audio from a standard USB-A plug, so it works on any host with a free port and OS-level audio support. Frequency response is specified as 20 Hz to 20 kHz. No other interface or analogue jack is provided.

Questions about this item

What does the USB connector on the AC-4006 limit in practice?

The USB connector carries both audio and power so the headset works without a separate sound card or batteries, and it is capped by the host device's USB audio implementation.

What physical space does the AC-4006 need to fit around the head and ears?

An adjustable headband stretches to suit different head sizes while leatherette ear pads sit over the ears, so the headset only requires enough room for the padded cups to rest comfortably.

How is the AC-4006 installed, and what step do people often miss?

Plug the TuffCord USB cable into a free USB port — no driver installation is required — but users sometimes forget to select the headset as the default input and output device in their system sound settings.
