Bluetooth didn't work at all. The position of the tubes was extremely flimsy. I encourage you to shop around, save some money, and buy a reliable tube amp that actually supports Bluetooth. This product acts more like a toy than a tube amp. By the way, I tried to connect to three different iPhones in our house. didn't connect at all. I have no idea if this is an isolated case. However, returned this item after 2 hours of continuous Bluetooth connectivity troubleshooting.
