Principle of Operation

The headphones reduce noise through passive attenuation while allowing the use of audio functions without removing protection. When connected via Bluetooth, you can play music, make calls, and control basic functions directly on the ear cups. The built-in ambient listening mode allows you to perceive conversations and external sounds when this function is enabled. Receiving FM and DAB+ radio enables use of radio signals while working.

In Practice

The low attenuation value of 30 dB SNR supports protection in loud environments, while the ergonomic design and soft cushions increase comfort during long-term use. The long battery life reduces the need for frequent charging, which is important during entire work shifts. Bluetooth connectivity allows calls to be received without interrupting work, and FM/DAB+ radio enables listening to audio programs where needed. The IPX4 protection class increases usability outdoors and in light splashing conditions. In daily use, it helps where hearing protection and constant access to audio are both needed.
