Thanks for sharing your detailed feedback on the Galaxy Buds3 Pro. We appreciate your insights and want to ensure that you have the best experience possible with our devices. The Galaxy Buds3 Pro are designed with advanced features like Adaptive Equalizer with Galaxy AI, which tailors your sound based on how you wear your Buds, ensuring immersive audio on-the-go. However, we understand that the left earbud becoming quiet can be frustrating. Cleaning the microphone hole, speaker, and air duct can often resolve this. Before cleaning the speaker, detach the ear tip from the latch at the bottom of the earbud and remove any earwax or debris with a clean, dry, and soft brush, cotton swabs, or other tools. Be gentle to avoid damaging the components. Make sure you are wearing the earbuds correctly and adjust the volume using your device. Also, check the battery status of your earbuds and ensure they are fully charged. If you can't hear sound well during calls, check if Ambient sound mode is enabled. Sometimes, a simple restart of your phone and earbuds can resolve audio quality concerns. Lastly, ensure your earbuds have the latest software updates. If you need any further assistance or have more questions, please don't hesitate to reach out to us at Samsung Support. -Kelvin
