Walkers GWPXSEMBT XCEL 500BT Electronic Earmuff 26 dB Gray. Walker’s Xcel Muff Series was inspired by taking an unconventional approach to engineering the best electronic hearing protection muffs available. The patent pending design moves the digital control panel and microphones off the muff cup to the headband, resulting in more air space inside the cup helping to deliver better protection. It utilizes an advanced digital circuit, dynamic sound suppression, Hi Gain Omni directional mics, and four (4) listening modes: universal, speech clarity, Hi frequency, and power boost. The Xcel Muff also features rubber bumpers on lower cup, wind noise reduction, voice mode navigation, and auto shut off. It is powered by two (2) AAA batteries which are included. This model has Bluetooth connectivity and a gray finish.
