Review on Langsdom Bluetooth Headphones - Wireless 3 EQ Setting, CVC 6.0, Bluetooth 5.0, Sports Magnetic Earbuds, HD Audio, 9 Hours Playtime, Noise Cancellation, Wireless Earphones with Built-in Mic, IPX6 Waterproof (Black) by Laura Tolson

Pretty inconvenient, uneven connection when you have two devices and are 20-30m from an unused device it cuts out your music, calls etc so you know it's with the second device is connected and that it will disconnect from the second device when you are out of range. annoying when listening to music while mowing the lawn. Constant bluetooth crashes even when my phone/other device is less than a foot or two away I assume this is normal. When it works, it sounds good, not great, but good. When it bit the dust, that annoying voice, which I believe is used for every Chinese Bluetooth headset, just casually said "Turn off the device", then it wouldn't turn back on, nor would it charge . In general, good luck.
