Thank you for your reply. Unfortunately this did not solve the problem with my husband's hearphones. I followed your instructions very carefully but still, when plugging the hearphones in to charge, they flash yellow for a few minutes then change to flashing red.
Thanks for coming back to tell us how you are doing. I'm sorry this attempt to restore the charging function did not work for you.
Please call us at 1 800-761-2673 and we'll take care of you.
