Thank you for sharing your experience with the Galaxy Buds3 Pro, Edgar! We appreciate your feedback and understand your concern regarding the screeching sounds. One of the key factors that can affect audio quality is ensuring that you have the right-sized ear tips. The Galaxy Buds3 Pro comes with different sizes, and a proper fit is essential for preventing sound leaks and providing optimal audio performance. If you haven’t already, we encourage you to check out our guide on Samsung.com for changing the tips. Once you’re equipped with the correct ear tips, please make sure you’re inserting the earbuds properly. Check the directional marks on the bottom of the earbuds—'R' for the right and 'L' for the left. Insert the right bud into your right ear, angling it slightly so that the microphone is pointing towards your mouth. The left bud should be inserted accordingly as well. Adjusting the buds by rotating them can help achieve a more comfortable and effective fit. Additionally, if the earbuds are not fitting securely, it may lead to unwanted sounds like screeching. We recommend running the earbud fit test available in the Galaxy Wearable app, which can assist in ensuring you have the proper fit. We’re committed to helping you get the best listening experience possible.
