Cyber Acoustics ACM-70B Headphone 27mm 3.5mm 6.00ft

Lightweight Stereo Headphones for Everyday Use

The Cyber Acoustics ACM-70B is a supra-aural stereo headphone designed for PC, Mac, Chromebook, tablet, smartphone and most gaming system users. It houses 27mm dynamic drivers covering a 20Hz–20KHz frequency response. The adjustable headband and soft leatherette ear pads provide a comfortable fit for users of all ages. This lightweight, travel-ready option suits classrooms, travel or daily listening without requiring software installation.

Passive Operation with Tangle-Free Cable

These headphones draw power directly from the 3.5mm audio source, so there is no battery to charge and no active circuitry to generate heat or noise. The 6.00 ft braided TuffCord resists tangling and withstands coiling, twisting or chewing without performance loss. Weighing 0.12 lb, the set adds negligible load during extended sessions. No thermal management or fan noise considerations apply to this passive analog design.

Plug-and-Play Convenience and Durable Build

The 3.5mm connector enables immediate plug-and-play compatibility across listed devices without drivers or configuration. Leatherette ear pads are easy to clean and the adjustable headband accommodates most head sizes for shared use. Buyers who need wireless freedom, active noise cancellation or a detachable microphone will not find those features here. The bundled TuffCord cable is the only included accessory, replacing standard wires with a rugged nylon braid.
