Customer: Tested the Peltor Tactical XP headset with a FSII BP and it worked perfectly. The headset uses an electret capsule. Basically this headset is a normal passive Peltor headset but has additional ambient-mics attached on both sides and you can add ambient noise. So it’s not based on noise cancelling but gives you a very high passive attenuation adding again ambient noise with headphones. The level of the ambient noise is adjustable, also a DSP is added so you have a kind of compressor effect.In a normally loud environment you can talk to a person next to you. As soon as the loudness around you increases the DSP in the headset compresses the ambient noise. Very nice but also very expensive.
