How to clean the OWS 2?

If you want to clean the OWS 2, you could use a fine dust-free cloth, dip a small amount of alcohol with a concentration of 75%, and then gently wipe the top cover in one direction (the alcohol should just wet the cloth, not soaking through). If there is only alcohol wet tissue, wring it out before use to avoid the liquid alcohol inflow into the earbuds and affecting the bonding firmness.
