Review on Studio Wireless Pro-C Y80B Headphones with Mic, Wireless Bluetooth 5.2, 110h Battery Life/Wired, Shareport by Adam EK ᠌

Maybe this is a purely subjective characteristic, but after the previous headphones in these I lacked high frequencies at first, and the low ones seemed too booming. But perhaps this is psychoacoustics and after that it became addictive. I admit another option of the second - they require "warming up". After reading on the Internet about headphones with membranes, I found out for myself that such headphones require some time to "warm up" in order to sound better. It took me about a week of average listening time per day, when everything became normal for me) But I think it's worth warming up idle without wearing headphones to make sure this is a working method - just turn on the music at medium volume and leave it like that for a few hours, and then compare with what it was before "warming up" or take measurements.
