First of all, the earphones must be protected from large vibrations. The moving iron units of the customized earphones are fixed inside the cavity, but they are not very strong, so avoid collisions, drops or impacts.
Custom earphones should not only pay attention to anti-vibration, but also pay attention to moisture-proof during normal use. Once moisture enters the earphones, it must be dried in time. It is also necessary to pay attention to earwax and ear oil entering the inside of the earphones, which will cause damage to the earphone unit.
Then there is the cleaning of the nozzle. Custom headphones are a type of in-ear earplugs, so their tuning is the same as custom earplugs. The tone orientation of custom headphones depends to a large extent on the state of the nozzle catheter. If the earwax is cleaned If it is not timely enough, it is very likely that the nozzle of the custom earphone will be blocked.
