Classroom headset with 3.5mm combo plug

The Cyber Acoustics ACM-4004 is a stereo headset built for daily classroom use. A single 3.5mm CTIA plug connects directly to Macs, Chromebooks, newer PCs, tablets and smartphones without adapters. Weighing only .2kg, the over-the-head design stays light during long lessons or testing sessions.

Leatherette pads and braided TuffCord

Leatherette ear pads provide a comfortable seal for extended wear. The adjustable headband fits a range of head sizes. A braided TuffCord resists tangling and daily pulling, while the classroom-tested construction withstands repeated handling by students.

Wired simplicity for shared devices

This headset replaces fragile consumer earbuds or bulky USB sets that need drivers or extra ports. The analogue combo jack works instantly on any device with a CTIA socket, making it ideal for carts, labs or 1:1 programmes where quick swaps matter. It is not for users who need wireless freedom, active noise cancellation or a detachable boom microphone.

Questions about this item

Will the 3.5mm combo plug on the ACM-4004 work with my older PC that has separate headphone and microphone jacks?

The single 3.5mm CTIA plug carries both audio and microphone signals; older PCs with separate jacks will need a Y-splitter adapter to connect both functions.

How can I confirm the ACM-4004 headset is functioning correctly after plugging it in?

Play audio to verify stereo output through the leatherette ear pads, then record a short voice clip to check the microphone is active via the combo plug.

Does the ACM-4004 package include a splitter for dual-jack computers or must I buy one separately?

The box contains the headset with braided TuffCord and adjustable headband only; a 3.5mm Y-splitter for separate mic and headphone ports is not included.
