Review on 🎧 Sennheiser HD 350BT White Wireless Headphone: Bluetooth 5.0 with 30-Hour Battery, USB-C Fast Charging, Virtual Assistant & Foldable Design by Jnis Gailis ᠌

1) In the left earpiece (where there are no buttons), when the music is turned off, a quiet squeak or whistle is heard. If you do not listen to music, then after 10-15 seconds the whistle disappears, apparently the amplifier goes into sleep mode, but in pauses between music or in quiet moments it is clearly audible. 2) absolutely idiotic volume control - when you press the volume button to indicate pressing, the headphones start beeping ~ once a second, but at the same time, during the peak, the volume of the music fades for half a second, then increases again, then for the next "peak" the sound fades again. In short, the effect is like if you very quickly turn the volume to the maximum and to the minimum, many times in a row. The head is spinning. 3) the microphone is very strange. It amplifies the ambient sound and everything in detail and with amplification broadcasts to my ears. I hear myself with headphones better than without - my voice, breathing like putting on a stethoscope and listening to your lungs, my stomp on the floor, as I grab the door handle, the rustle of my jacket, etc. (This is during a phone call! ). In no headset, no phone, the microphone amplifies the sound of the microphone into your own speaker! 4) there are not enough high frequencies, although this may be due to codecs, but this is not a big problem.
