In general, I do not recommend buying. Because of the whistle when charging, I wanted to give up, but I listened to the seller that these are typical problems for wireless headphones. I think to look at similar ones, if they donβt have similar problems, Iβll hand over these. Got pros: As for me, a decent sound, a decent microphone, but nothing special. Some cons: At maximum volume, the wireless connection is a little buzzing. When charging, a slight whistle is heard in the speaker, to which the charging wire is connected. At first there were problems with a wireless connection, but now everything has somehow stabilized. They sit down pretty quickly.
