3M PELTOR ComTac V has Omni-directional microphones and high fidelity speakers that are optimized to transmit voice communication and can pick up sounds with great sensitivity with an excellent signal-to-noise ratio for clear and accurate sound replication. The result is a more natural sounding headset with unmatched sound clarity. 3M has replaced the leather headband, for a more modern rubberized band that is easy to remove if the user wants to convert to ARC adapters (or convert back to a headband). This headband has increased environmental resistance to heavy maritime environments.Features :Level Dependant, Electronic Hearing Protection to Help Protect from Impulse and Steady State NoiseRugged 3M PELTOR Design for Trusted PerformanceEarPlug Mode for high noise environmentsOmni Directional Environmental Microphones for Level Dependant Hearing protection and Auditory Situational AwarenessNRR = 23dB (with equipped foam earseals)
