Thank you so much for taking the time to share your feedback on the Galaxy Buds3 Pro, Halukitty. We always appreciate hearing from our valued customers. It's awesome to know that you're satisfied with the sound quality and battery life. We understand that having a great fit is also an important factor in your overall listening experience. We recommend using different-sized ear tips with the Galaxy Buds3 Pro to ensure a proper fit. Start by selecting the right size tips for your ears, making sure there are no gaps between your ear and the tip to avoid sound leaks and optimize audio quality. To insert the earbuds, check the bottom for directional markings — an "L" for the left earbud and an "R" for the right. Insert the R earbud into your right ear with the "R" facing you and the L earbud into your left ear with the "L" facing you. Angle the earbuds slightly so that the microphone on the bottom points towards your mouth, and adjust the fit by rotating them forwards or backwards until they feel comfortable. You can also run an earbud fit test in the Galaxy Wearable app to confirm that you have the proper fit. We hope you continue to enjoy your experience with the Buds3 Pro.
