Noise-canceling headphones YT-74626 with a wireless connection module using Bluetooth technology.

These allow you to connect to most smartphones, tablets, some laptops and other devices equipped with Bluetooth technology.

Four function buttons on the side of one earcup allow, among other things, to adjust the volume, answer and end a call, or switch between the next music track.

The headphones can also be connected to some smartphones using the included plug cable.

Thanks to the built-in AUX port, it is possible to listen to music in stereo and record the caller's voice during a call (in this case, the voice is transmitted via the phone's microphone).

How to choose headphones for the workplace:

Protective noise-canceling headphones provide the operator with protection against harmful noise, reducing the sound level measured in decibels by the value of the SNR parameter.

The upper limit for an 8-hour working day is set at 85 dB.

If the average sound level measurements in the workplace exceed this value, you should get headphones that allow you to reduce the noise level to 85 dB and below.

Assuming that we are constantly working while wearing headphones with an SNR parameter of 29 in a work environment with a noise level of 113 dB, we reduce the noise to 84 dB.

If the user wears headphones for more than a few minutes, it is worth paying more attention to the design elements that improve their wearing comfort.

Sufficiently wide sealing pads made of skin-friendly materials should cover the entire user's auricle.

The soft padding of the headband relieves pressure on the top of the head.

On the other hand, the strength of the headphones' attachment to the head affects, in addition to comfort, the effectiveness of the attenuation.

Therefore, for continuous use, it is worth choosing headphones that do not necessarily have the highest available, but have a correctly selected signal-to-noise ratio (SNR).
