Certified Microsoft Teams Headset

The EPOS IMPACT 430T is a mono on-ear headset built for professionals who rely on Microsoft Teams for daily communication. Its plug-and-play USB Type-C connection works instantly without extra drivers, and the 32 Ohm impedance suits standard office devices. The 1001254 model targets hybrid workers needing a single-ear design that keeps them aware of their surroundings.

Sustained Call Clarity

During long meetings the electret condenser microphone uses uni-directional pickup to isolate speech from background noise, so voice transmission stays consistent rather than fading after a short burst. The 20 Hz to 20 kHz frequency response reproduces the full vocal range, ensuring every word remains intelligible across extended sessions. Lift-to-mute lets you silence the mic instantly without hunting for a button.

Lightweight All-Day Comfort

The ultralight frame and compact noise-dampening ear pads reduce pressure on the ear, keeping heat buildup low during continuous wear. A 5.91 ft cable provides enough reach to move naturally at a desk without pulling on the connector. With no embedded battery the headset draws minimal power from the host, running cool and silent throughout the workday.
