Shocks Open Run Pro not changing volume solved

I purchased the Shokz Open Run Pro headphones and had trouble getting the volume to change. At first I could only change it with the buttons on the headphones but previous pairs of headphones could be changed with the IPhones volume buttons. The only way I could make it work was to use the Shokz app and syncing the headphones to the app as well as the phone itself. Ow I have solved my issue. Hope this helps all my bone conductor friends!
