Hi Shopper! Thanks for your question about the Linkbuds Fit. We're happy to assist! This type of screeching or feedback, which is essentially an unwanted feedback loop, typically occurs due to three main causes that disrupt the sensitive Noise Canceling system: an obstruction such as dirt, earwax, or moisture blocking the sound output holes or microphone openings; an improper fit that prevents a perfect air-tight seal in your ear canal, which is essential for the function; or the microphones picking up and amplifying external contact from things like wind, body movement, or the earbud brushing against your ear. What you can try right away: 1) Remove earbud tips and clean the sound output holes, microphone holes, and sensors with a dry, soft cloth or cotton swab. 2) Ensure the earbuds are fitted snugly and the correct size tips are used. The Sony | Sound Connect app can help determine the best fit. 3) Make sure the earbuds are running the latest firmware via the Sony | Sound Connect app. If cleaning and fit adjustments do not resolve the issue, perform an initialization to restore factory settings.
