REDESIGNED ANTI-CLOGGING FILTER: Unlike some other IEMs on the market, MOONDROP implements an acoustical damper and filters into one package in order to make precise control of the frequency response. Its inner damper suffers some risk of contamination by vapor or earwax which causes volume imbalance. To fix that we developed a new triple-layer anti-clogging filter/damper. It effectively reduces risk of clogging issues that ends with volume imbalance.

PS: Due to the Special design of our filter, we don’t recommend any aftermarket filters as they may cause obvious acoustical degradation.

FILTER INSTRUCTION:

1. Please press on one side of the original filter with the tweezers until the filter cocks up.
2. Take out the original filter. 
3. Get a new filter with tweezers.
4. Put the new filter in edges-justified.
