Amplifies background noise instead of attenuating it - Walkers XCEL 500BT Digital Electronic Bluetooth Ear Muffs

Bluetooth ear muffs should do the double duty of doing real work, using them for shop and construction work, as well as the decadent leisure of firing off ammo. There's no setting to turn off the microphones, so they amplify ambient sounds like motors, etc. instead of suppressing that sound. They also create a great deal of background static, giving the illusion of attenuation when a loud percussion shuts down the speakers. The headset is uncomfortable to wear- spring tension is so tight that the cheesy cushion presses all the way down to flat. There's just three mode levels of annoyance, all creating some degree of white noise. Sending them back, should OpticsPlanet ever acknowledge and respond to my request for an RMA.
