Avantalk Jogger bluetooth earphones stuck in red light. what to do?

I just bought this avantalk jogger bluetooth earphones. I’ve read the instructions, and was ready to pair them with my cellphone; so I turned on the earphones, to test, and then turned them off. Set the phone on discovery and kept the button on the earphones pressed for 7 seconds (to make the pairing) but instead of blinking red/blue as it says it should, the earphones stuck on red light, and don’t respond to anything. Should I wait for them to discharge? I can’t find info about the meaning of the red light, maybe it is on hold? I really don’t know…
