They worked great for several weeks. Now just do what you want. They randomly turn off, turn on, connect and disconnect. Sometimes they don't connect and are deleted from the phone's Bluetooth memory. Recently, communication stutters even with a phone that is 6 inches from the earpiece. And English. Holy cow, English is so bad that notifications barely sound like the word they're supposed to be. "Connected" means "connected". At 10% battery, he says "Lo Bab Tree" every 23 seconds. And that for at least 16 minutes. It's absolutely annoying.
