Why is the default transparency??? Would you like a tinny slightly delayed audio piped in? No? Too bad, every time buds have a connection interruption or nothing is playing, it goes to the worst mode it has. Meaning you have to open the app to get back to noise canceling. Please let me select my own default mode. One has to open the app to get to noise canceling mode but you can get between the other modes just by holding the button. So in summary, the hardware works fine.
