We paired it with a cell phone and placed a call. Almost immediately after we hung up, it lost BT connection. It may have been our phone’s fault. We repaired it and it stayed connected. We then played some music through it from the phone’s music app. It worked okay, but it seemed like the max volume wasn’t very loud.
Compare this to the REALLY LOUD audio when on a call, and it seems like this isn’t right. It would be nice to have a volume control (even if it’s just in the web page) that’s available when the device is playing BT audio of any sort. Ideally, it would be a volume switch on the device itself, as indicated in other posts.
