Many hardhat-mounted Senas have a mute feature. The TuffTalk Lite (v1.0.4) does it. It should be added because my coworker has to turn off their sena due to how loud the chainsaw comes through (I just saw another post complaining about chainsaw noise picked up on the mic) Also, the model that costs twice as much can do simultaneous music streaming and voice communication. Why lock a feature behind the paywall of a more expensive unit when it should work fine on the Lite, which is already ridiculously expensive?
