Since the latest beta firmware release, my Sleepbuds have been working much better for me, and the "switch to Sleep mode ambiance when I fall asleep" is working well for my routine. I am really happy with the experience now.
The question I have is, once sleep mode has been activated, is there any way to return to Bluetooth streaming mode without putting the earbuds back into the case? If I launch the Ozlo app it doesn't appear to reconnect to the buds without them being in the case. On the Ankers you could do this by "double tapping" the left earbud, but there are no controls on the Sleepbuds. Tapping the closed case (which I think does respond to taps?) would be a fine way to do this,
