Choose the ear tips that fit your ears best and take a fit test in the soundcore app to ensure you get the best ANC performance.
✳ Dust, earwax or other debris can accumulate in the earbuds. To maintain optimal sound quality, regularly clean your earbuds via using a cotton swab slightly moistened with rubbing alcohol to gently wipe the metal mesh filter under the rubber ear tips. Finally, ensure the alcohol on the metal mesh filter has completely dried.
