Application

This product is intended for use in environments with constant or intermittent noise, where there is also a need for making calls or using phone audio. It can be used in construction, industry, workshops, and on farms, for example when operating machinery, working in production areas, or performing tasks in noisy rooms. It is also useful when the user needs a compact solution for mobile work. This is a practical choice for those who want to combine hearing protection with everyday connectivity.

Operating Principle

The earbuds reduce the impact of noise thanks to their in-ear design, which creates an acoustic barrier and dampens surrounding sounds. Bluetooth features allow for calls and audio playback without reaching for the phone. The noise reduction microphone improves call clarity in noisy environments, and the Awareness mode allows environmental sounds to be consciously admitted. Additionally, the microphone turns off automatically at very high noise levels, supporting safe use in demanding conditions.

In Practice

The lightweight design promotes comfortable wear for many hours, which is important during long shifts or while working on the move. The charging case makes storage easier and allows for recharging the earbuds during the day, so the equipment is ready even while working away from the main workstation. Up to 8 hours of operation on the earbuds and up to 28 hours with the case increase freedom of use without frequent recharging. The black and yellow color scheme fits well with workwear and makes it easy to quickly find the earbuds among other PPE accessories.
