If you need helmet mounted headsets there are no better brand than 3M Peltor. 3M have a long and presteigious history making industry equipment.
The Peltor headset is heavy duty and built for use on ATEX sensitive areas such as refineries and petrochemical plants. The headset easily attaches onto ear cups of hard hats and features rotateable cups meaning when they are not in use you can easily move them out of the way for normal conversation.
The design is built around long shifts. The ear cups are foam and fluid filled cushions which keep out the noise whilst remaining really comfortable to wear. The most important part of the headset is the easily manourvable noise cancelling boom microphone which can be adjusted to exactly where needed.
This headset plugs into the Peltor ATEX PTT Adapter and can be used on any radio, providing the right PTT Adapter is used. The link above is for the Motorola DP4000 radios.
If you would like to use these on your radios, call us and we can provide a quotation for the correct adapter.
