Review on Wireless headphones JBL Tune 215 TWS, black by Akihiko Kichiro ᠌

The headphones were given to me as a gift. Unfortunately there were no receipts or guarantees. These are my first wireless headphones, I have only used wired ones before. The first impression is very good: clear sound, noise reduction, long work (never discharged). Unlike wired ears, there are a lot of advantages: you can run, ski without the risk of catching a wire (what can I say). But then a misfortune happened: once again placing them in a case and taking them out after, I found that the left earpiece had stopped working. After spending three hours dancing with a tambourine and such and such a mother, by some miracle I managed to get them to sync (as it seemed to me then, I knocked each other three times) After visiting the case again, the same problem, the old synchronization method did not work, but again somehow managed to make them friends, but, unfortunately, before putting them in the case. The third time I couldn't get the left earpiece to work. There are no buttons on the headphones or on the case. On the Internet, I did not find ways to synchronize this particular model. Not nice
