First, the old bluetooth 3.0. The experience of using two Plantronics 500, on three phones !, on all of them after six months there are problems with the headset, the first phone was lenovo, the second redmi, the third redmimax2 2022 !, and again problems with plantronics . plantronics 500 is also 2022! The problem is not in plantronics 500, but in the old version of bluetooth 3.0, after the ate, phones with bluetooth version 4.0-5.0 stop working normally with headsets 3.0!
