Hello Jeff{--B--},
Thanks for reaching Microsoft Community. We're sorry to hear about this issue on your earbuds. Definitely not the experience we want you to have.
If performing a factory reset on your earbuds did not work, then we suggest to test it on another host device.
If issue still persists, then we know it's potentially a hardware failure already.
For any hardware related issue, kindly contact our support via Contact Us Microsoft Support to seek exchange options for your earbuds and real-time assistance. You can also contact them via phone, see Global Support Phone Numbers.

Kind regards,
