The TMГ-8AM is a low-noise telephone-microphone headset engineered for clear voice communication in loud industrial and operational environments. Operating across 150–6,000 Hz, the headset combines a noise-selective microphone — with axial selectivity coefficient of at least 10 at 150 Hz against spherical sound fields — and earphones with controlled frequency response unevenness within 20 dB.
Powered by a 9 V Krona battery, it weighs no more than 250 g with a 1,000 mm cord, operates from -20 to +55°C and tolerates 98% relative humidity. This specification profile reflects its origin in professional and special-purpose communication equipment, where intelligibility beats audio fidelity.
At about USD 9 with a 200-piece MOQ, the headset suits communication equipment distributors, industrial-safety suppliers and operators of dispatcher, aviation-ground and machine-room systems who need rugged voice terminals at far below Western specialist-headset prices, with batch testing documentation supplied.
