Thank you for reaching out. I can certainly understand your concern with the buzzing issue with your Buds 3 Pro. For the buzzing issue with your Buds 3 Pro while active noise cancellation is on, it's good that you've already tried resetting and pairing them again. If the problem persists, I suggest checking for any available firmware updates for the earbuds through the Galaxy Wearable app. If there are no updates or if the issue continues after updating, it may be best to have the earbuds checked by a Samsung service center for further diagnostics.
