Bluetooth with good audio and reception and with a good sound, both grills independent for operation and charging, good sunglasses with good protection due to their polarization. Handling of the complicated and fragile bluetooth when independently charging each pin. I like it despite everything.
Good sunglasses with good sun protection. Good Bluetooth 5 transmitter and receiver that can be heard very well and is only heard by others at maximum volume. Easy to handle on calls and plays audio and music very clearly. It is a good product, I like it.
Although the charging of both pins is independent and makes the bluetooth channels independent, they listen well and receive well, they are paired correctly. The handling of calls by touch system is somewhat complicated but it works, the lenses of the glasses protect by their polarization and are resistant. I like them.
They came early. They look good. But they're broken, one side is not working - it can't even charge. I'm disappointed.
