Classroom-ready USB headset

The HamiltonBuhl ST2BKU is a wired stereo headset built for daily classroom use. Its USB 2.0 connector works directly with PCs, Macs, Chromebooks and most gaming systems without extra drivers. Over-ear leatherette cushions and a padded headband keep students comfortable during long lessons. The adjustable steel-reinforced headband fits a wide range of head sizes.

Dura-Cord cable and gooseneck mic

A five-foot chew-resistant Dura-Cord with braided nylon jacket resists kinks and knots in busy environments. In-line volume control puts level adjustment at the student's fingertips. The flexible gooseneck microphone features omnidirectional pickup with passive noise cancelling for clear voice capture. No separate audio jacks or power adapters are required.

Sustained comfort and clarity

Forty-millimetre drivers deliver a 50 Hz to 20 kHz frequency response at 32 ohms impedance and 100 dB sensitivity for consistent audio output. The microphone operates from 50 Hz to 16 kHz with a 2.2 K ohm impedance and -50 dB sensitivity. Lightweight construction at 0.42 lb reduces fatigue during extended testing or learning sessions.
