Unfortunately, after 3 months of operation, the headphones began to live their own lives, namely, each earphone became independent. One earpiece could connect to the phone, the other to the laptop, and so they played - both different music. The phone saw two bluetooth devices with the same name. If both of them are connected to the same phone, only one plays anyway. On reddit, I found that this company has such a problem in general, but there is no particular solution. Dancing with a tambourine and resetting to factory settings did not help in any way. Finally got it back under warranty. It's a pity, the headphones are cool.
