Range of headsets and communication products offering ear protection in acoustically hazardous environments such as shooting, industry, construction etc. These are all compliant with the Control Of Noise at Work Regulation 2005 and suitable for a range environments.
Not all ear defenders just protect the ears by means of their insulation. Some models dynamically allow sound to pass through, even increasing weaker signals, but will automatically create an acoustic shield in the event of sudden high volume sound.
This can also benefit environments where there is a constant level of high volume but communication is still required. There are a range of ear defenders that incorporate 2 way talk via Bluetooth, DECT or more commonly radio while still providing protection from hazardous noise levels.
