HMEC 45-KA

HMEC 45-KA Supraural Active Noise Reduction Headset
The HMEC 45-KA Open Aire headset features the NoiseGard system for active noise compensation. Ambient noise in the frequency range between 400 and 1000 Hz is effectively reduced by 10 dB. The excellent sound reproduction is paralleled in its quality by a noise cancelling back-eletret microphone for clear speech transmission.
