In order to have the best sound quality for Model Y, the nozzles should be clear of any debris or earwax. The following steps will help keep the nozzle's clean.
1. Remove the silicone tips from both monitors. Gently wipe down the silicone tips with a moist paper towel.
2. Take an alcohol pad and gently wipe down the body of the monitors. Please make sure that the metal connectors are wiped down and allow them to dry completely before placing them back into the case.
3. Take an alcohol pad and gently wipe around the nozzle. Do not press against the protective sweat guard. Wipe around the plastic to remove any ear wax. Then take a cotton swab and gently swab any oils from the screen.
4. Take a cotton swap and gently swab the inside of the cavity of the charging. Twist the cotton swab to remove any oil build up. Take an alcohol pad and carefully wipe down the metal connectors.
Once everything is completely dry, place the silicone tips back into the nozzle and place the monitors back into the case.
