The bluetooth is disconnected when the magnets of the inserts are closed, it connects when it is opened. The right and left sides weigh the same - do not slide to one side. In general, very satisfied. Its pros: Autonomy (they work long enough, 15 hours for sure). Good sound (the insert in the ear gently compresses the auditory canal, cutting off third-party sounds and adding good sound transmission to the headphones). Appearance. Nice coverage. Ear fixation. Convenient charging, fast charging. Easy switching between 2 devices (I have not tried more devices). Cons below: Signals (on, off, connection) are not words, but sounds. Noise canceling does not remove high-pitched sounds well. For some reason, the on-off button (perfectly pairs with the middle button (pause / start), judging by my previous headphones of this type). Noise reduction / transparency / OFF modes are switched only on the left side (and here they are voiced by text, but for on / off and connection - no, which is somehow stupid).
