Home Theater Questions? Ask a Technician for Answers ASAP
Hi and welcome to the site, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.
Initially, please; confirm what device is the Bose SoundLink Mini II used with ? ...describe how is the connection made.
Is the described issue of "...voice are not clear..." commonly experienced with Bluetooth and 3.5mm connections?
And have you considered / tried a RESET of the Bose?
