Review on Sony WIC400/L Wireless Behind-Neck In-Ear Headphones, Blue by Krisha Kanth ᠌

Headphones are good. The sound is normal, unremarkable, easily corrected by the equalizer. Great battery life and fast charging. On the neck are not felt, worn comfortably. The wires seem flimsy and thin, but only seem. They also have length regulators, but unfortunately they just exist and do not properly perform their function - the wires quietly slip through the rubber band that should hold them. And the worst thing, but as far as I understand it, all wireless headphones have signal interruptions. In the metro they work without interruptions, on the street, if somewhere nearby there are transmitters operating at the same frequency as the headphones, the sound disappears and "breaks". It's very annoying and can cause you to stop using your headphones.
