I'm ating my review after 3 months of use. Total downgrade since xm3. The bottoms and tops are now not audible at all, you have to correct the equalizer. The battery was killed in the soup! Two and three could hold a charge for several days, this piece * is discharged in 5-6 HOURS! That is, on long flights in an airplane, you will have to recharge at least 1 time. At the same time, it is still impossible to use the ears along with charging. How many years have passed since xm1? 4 like?
And most importantly, everyone understands perfectly well that it’s not only the battery size (headphones have lost weight, what could they sacrifice), it’s just that the processor began to eat a lot more. It would seem that add one slider to the application so that you can control the level of noise reduction. But nooo, why, let's better cram the sounds into 360. Let's better add a paid subscription to music that can be downloaded for free if you type "8D music" on YouTube.
All metal was also removed from the case, now the headphones do not look like a premium segment product, like the same BV, but like a Chinese craft with Ali.
Added "chat". God, I hope the freak who came up with this x * yu was fired after writing a couple of unflattering in the labor. So: by pressing the panel with TWO fingers, you automatically turn on the mode in which ANY word spoken next to you will become a trigger to turn on the function that skips ALL SOUNDS AROUND ALL! An ordinary example: the cashier offers you a package, but the headphones think that it's time to turn off your music! This feature is enabled by default, and I didn’t immediately realize that it was turned off through the application, or by holding two fingers.
The touchpad itself has become MUCH worse. She may not respond to wet fingers, but if you lie down on a pillow, jokes will begin with "chatting", stopping / starting the track, etc.
They killed the automatic connection, at least on the Samsung. Vx-1/2/3 calmly connected to the device AUTOMATICALLY, but not the four. Now you need to constantly climb into the settings and connect your ears with a manual.
