the type of earwax you have comes down in part to your skin type, Dr. Shapiro explains. People with oilier skin may have wet earwax, while those with drier skin tend to have dry earwax, she says.
People of East Asian descent are more likely to have dry earwax, while wet earwax seems to be more common with everyone else
If you are the wet type you may reconsider buying expensive in-ears. The chance to ruin them quite fast is not that low.
