Electronic earmuffs with bluetooth (YT-74626)

Noise ear muffs YT-74626 with a wireless communication module using bluetooth technology. They allow pairing with most smartphones, tablets, with some laptops and other devices equipped with bluetooth technology. Four function buttons on the side of one of the earcups allow you to, among other things, adjust the volume, answer and end a call or change to the next music track.

The earbuds 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 pick up the sound of a caller while making a phone call (in this case, the voice is transmitted through the phone's microphone).

Technical data:

• suppression efficiency: SNR 29 dB
• maximum talk time: 8 hrs
• charging time: 3.5 hours
• lithium-polymer (Li-Po) battery with a capacity of 750mAh allows operation even at low temperatures and features high mechanical durability
• weight: approximately 350 grams

Working comfort:

• large and wide cushions distribute pressure over a larger area of the head and do not compress the auricles
• flat 35mm wide adjustable headband with elastic support distribute pressure over a larger area of the head making the headband almost imperceptible even after several hours of use

Additional information:

• Sound and light low battery alarm
• Micro USB charging port with red/green led indicator
• USB charging cable approximately 50cm long
• 3 .5mm AUX port
.
• 3 .5 mm jack cable with a length of 110 cm
• the knob is used to adjust the volume when connected via cable, when connected wirelessly the volume is adjusted using the function buttons on one of the earcups

Examples of use:

YT-74626 ear muffs combined with a smartphone allow you to listen to music comfortably while doing work in excess noise, and can also be used as a headset for phone calls. All kinds of noise, for example, in machining workshops, carpentry shops or production halls, is reduced by as much as 29dB.

How to choose earmuffs for the workplace:

Protective, anti-noise earmuffs provide protection for the operator from harmful noise by reducing the volume level measured in decibels by the value of the SNR parameter. The upper limit for an 8-hour workday has been set at 85 dB. If the average loudness measurements in the workplace exceed this value, then you should get ear muffs with a SNR parameter that will allow you to lower the noise level to 85 dB and less. Assuming that we will work all the time wearing earmuffs with SNR parameter 29 while being in a work environment with a noise level of 113 dB, then we will reduce the noise to 84 dB.

If the wearing time of the earmuffs by the operator is longer than several minutes, then it is worth paying more attention to the design elements that improve the comfort of wearing them. Adequately wide sealing cushions made of skin-friendly materials should accommodate the user's entire auricle. Soft padding on the headband will relieve pressure at the top of the head. On the other hand, the strength with which the earcups adhere to the head has an impact not only on comfort, but also on the effectiveness of damping, so for continuous operation it is worth choosing earcups with not necessarily the highest available, but properly selected SNR parameter.
