Zekler 412RDB level-dependent Bluetooth radio earmuffs incl. battery + charger

Comfortable earmuff hearing protector with built-in FM stereo radio, ambient sound level-dependent function, and wireless Bluetooth technology for calls or music playback. Batteries and charger included. Music streaming pauses and the FM radio is muted when there is an incoming call, while the level-dependent function remains active for safety reasons. Excellent attenuation of low, high, and mid frequencies. Headband with fork-type attachment and wide comfort-enhancing sealing rings that keep the headband pressure evenly distributed.

• Wireless Bluetooth connection for, for example, a mobile phone, laptop, or iPad. 
• Boom microphone with highly effective noise cancellation for clear, crisp communication even in very noisy environments. 
• The Side Tone function lets you hear your own voice clearly, making it easier to speak at a normal voice level even in noisy environments.
• The level-dependent function remains active during incoming calls for safety reasons.
• The Adaptive Volume Control function automatically adjusts incoming call volume based on the surrounding noise level.
• FM stereo radio 88–108 MHz with sound level limitation (82 dB(A)).
• The Automatic Frequency Control (AFC) function reduces noise between stations during scanning and locks onto the selected station so it stays tuned even in poor reception conditions.
• Automatic stereo/mono switching stabilizes the sound field according to reception conditions.
• The ambient sound level-dependent function, Level Dependent System, amplifies weak sounds and allows ambient sounds to be heard while the ears remain effectively protected against sudden loud noises.
• Attenuation level: Level 2.
