Product description
ACM-4004 Audio Schools Can Depend On During State Testing
State testing starts with consistent audio. Our headsets and headphones deliver clear, uniform sound for every student, reducing interruptions, simplifying troubleshooting, and helping schools maintain focus and accuracy during computer-based assessments.
Classroom-Tested Technology
We asked teachers what their top problems are with headsets in their classroom. From chewed cords to broken headbands, damaged plugs, headsets that are hard to clean, and worn-out earcups: we solve them all.
Chewing
Cyber Acoustics headsets feature tangle-free, ultra-durable, and braided TuffCords that can withstand even the toughest chewers.
Connectors are a Common Stress Point
Broken USB and 3.5mm plugs are a top complaint from school IT departments. That’s why we have a steel rod in our 3.5mm plug and an improved USB design for added durability at this common stress point.
Earcup Stitching
Cyber Acoustics’ easy-to-clean leatherette earpads are double-stitched internally for improved durability.
Broken Headbands
Our durable headbands withstand thousands of stress cycles. AC-4000, 5000, and 6000 series endure rolling, twisting, and bending backward without breaking – even against the toughest students.
Difficult to Clean
All of our education-based headsets and headphones come with simple to take care of, long-lasting, and easy-to-clean leatherette cushions.

Why are these headphones in a bag?
We use reusable, resealable, and recyclable poly bags for these headphones. The poly bag reduces single use plastics in packaging and is perfect for storing the headphones when not in use.
How long is the cable?
These headphones feature a 6ft cable giving users plenty of slack to work with without tugging on the connector.
Why can’t I hear anything?
Double check all the settings on your computer and make sure that the headphones are selected as the audio output. Test the headphones with another device. If the headphones work on another device you might need to update the computer audio drivers.
How do I adjust the headband?
If the headset feels too small, you can expand the headband by gently pulling on each side to extend it. The adjustable sliders built into the headband allow for a more comfortable fit on different head sizes.
With an adjustable headband and leatherette earpads these on ear headphones can be adjusted to fit most head sizes
Simply plug in and play no installation needed; connect 3.5mm plug directly to any compatible device
Durable design includes headband that can be bent and twisted and a braided TuffCord
Includes ACM-4004 heaphone, one year warranty
