Thanks for reaching out and welcome to the Bose Community Forums.
I am sorry that you are having issues with your SoundSport headphones. I would love to try and help you to resolve this issue. Could you please try the following steps and let me know how you get on?
Go to btu.bose.com on a computer and update your headphones software.
Perform a product reset, to do this, turn off the headset and wait 30 seconds and then plug the headset into a wall outlet using a USB charger, then wait 5 seconds. After that unplug the USB cord from the headset and wait 1 minute once you have completed this turn the headset back on.
