This is an awesome item for anyone who works in a loud noise environment. It is the Sensear SmartMuff headset. It is a must for any loud environments that can cause damage or be very hard on the ears. It is currently selling for $400 on Amazon. It is brand new inbox and they have never been used. I was going to start a job that would require them, but I never did so I have no use for these. Please see the photos so you can read all the specific and incredibly impressive stats about these. A few of them include : -Up to 27db Noise reducing rating -Sens Technology -24 hour battery life. Only 5 hours for a complete charge. -Maximum in ear noise exposure of 82db with built in limiter -Can listen to FM radio -Bluetooth connectivity and communication -2 way radio communication I am asking for a fraction of what they are currently selling for. Please feel free to ask me any questions. I have over 300 Poshmark sales so you can purchase with confidence.
