The extreme noise cancelling dual-muff headset is extremely popular with the manufacturing, mining and other noisy industrial groups. The ear cups have been manufactured with acoustic noise reduction material coupled with the gel ear pads that mould comfortably around your ears efficiently minimising background noise. The boom microphone is fitted with a high performance electret noise cancelling microphone. The headset is manufactured standard with the positive action earmuff PTT. However, if you chose to purchase the cable with the large high-quality inline PTT button you can use either the Earmuff PTT or the large inline PTT button providing flexibility with different staff preferences.
