A10 Charging questions

What is the best way to charge the sleepbuds?
I leave them charging all day, and when i go to bed and get ready to put them in, they are only half charged.
Leave the case open?
Close the case?
Thanks

I do not own a pair, but typically the earbuds should be placed in their case and the case closed. I would make sure your charging block is providing the necessary power output for what the buds require. I have had many issues in the past because I hook up a device to a low power charger and find out later it isn’t charging as fast as it should.
