They enable pairing with most smartphones, tablets, some laptops, and other devices equipped with Bluetooth technology. Four function buttons on the side of one of the cups allow you to adjust the volume, answer and end calls, and change to the next music track , among other things. The earmuffs can also be connected to some smartphones using the included jack cable. Thanks to the built-in AUX port it is possible to listen to music in stereo, as well as receive the caller's audio during a phone call (in this case, the voice is transmitted through the phone's microphone). Large and wide cushions distribute pressure over a larger area of the head and do not put pressure on the auricles. The 35 mm wide, flat, adjustable headband with a flexible support distributes the pressure over a larger area of the head, making the headband almost unnoticeable even after several hours of use.

The upper limit for an 8-hour workday has been set at 85 dB. If average noise measurements in the workplace exceed this value, then earmuffs with an SNR value should be purchased, which will reduce the noise level to 85 dB or less. Assuming we will be working continuously with earmuffs with an SNR of 29 in a work environment with a noise level of 113 dB, then the noise will be reduced to 84 dB. If the operator wears earmuffs for longer than a dozen or so minutes, it is worth paying more attention to design elements that improve comfort. Sufficiently wide ear cushions made of skin-friendly materials should accommodate the user's entire earlobe. Soft headband padding will alleviate pressure on the top of the head. The force with which the earmuffs fit the head affects not only comfort but also attenuation effectiveness, so for continuous use, it's worth choosing earmuffs with a properly selected SNR parameter, not necessarily the highest available. **
