New Walkers Game Ear Xcel Pro Bluetooth Razor Muffs. XCEL 500BT combines sophisticated sound processing, intuitive menu navigation, and rich electronic control features with an intelligent, forward-thinking approach to design and ergonomics that delivers a hearing protection and enhancement system without precedent in the shooting sports and hunting industries. The XCEL 500BT’s next-generation Sound-Activated Compression and variable Dynamic Sound Suppression automatically adjusts compression time according to noise level intensity and duration instead of using conventional “fixed-time” compression. The result is improved hearing protection regardless of the sound environment. Additionally, the XCEL 500BT allows the wearer to select between four different listening modes: Universal (for sound amplification), Speech Clarity (for discriminating voices and enhancing verbal communication in a noisy environment), High Frequency (tuned specifically to hear steel target impact at long distances), and Power Boost (amplifies sound across the range of volume). All these modes are accessible via the soft-touch button control panel located on the headband. Voice prompts for the entire menu allow the user to select the available operational modes. This makes navigation very simple and removes the guesswork as to which mode the unit is in. The XCEL 500BT also comes with programmable auto shut-off, so forgetting to turn the muffs off and accidentally running down batteries is a thing of the past. Bluetooth compatibility is another valuable feature. By pairing the XCEL 500BT to a mobile device, calls and notifications connect through the muffs. Messages and conversations can be heard clearly even in noisy environments. Variable Dynamic Sound Suppression. Hi Gain Omni Directional Mics. Four listening modesVoice Mode Navigation.
