When it works it is okay but you can't count on it. Sometimes music won't play or sounds that are turned off in apps will start when you connect bluetooth. Bluetooth sound quality will deteriorate and you have to force the device to fully un-pair then re-pair. Seamless switching does not work, you always have to explicitly turn on and off bluetooth and select the device (samsung galaxy buds). Now it wants a whole ton of permission that it really doesn't need. I am just using buds pro earbuds
