The sound is great bt the app is utter rubbish.Keeps having problems connecting with my devices.Very tiring to always go thru the connecting process after every app update.I dun mind going thru the process if it connects and works.My goodness.The agony of it not working is ultimatum N always happens at the wrong time when I needed the earbuds most. Losing faith in the products and will not recommend anyone to purchase the Bluetooth products. B & O, do something. Time to invest in a better app.
