For those having issues with their Devialet Gemini, I received this response from support and it seems to have fixed my issues. Hope it help some of you!
Hello,
Thank you for your response.
Your headphones are up to date, good news.
I invite you to perform the following manipulation:
- Remove and put the earphones one by one in the case.
- Close the case
- Press the button, and in the meantime
- Open/close the case twice in a row
- Release the button
Did the light turn flashing orange and then green for a moment?
If yes, the reset has been well done, and you will be able to put the box in pairing mode again.
Forget in your phone's Bluetooth settings any device linked to Gemini.
Then repair with Gemini L and pair with R.
This should solve the problem you are experiencing.
Feel free to come back to me if you need me.
Wishing you a very nice day!
