The earplug wearing test has always shown that putting headphones into

The device shows that the earphone is put in because the earplug is not suitable and the earplug is clean.

1, the earplug is not suitable: the earplug size is not suitable for the ear canal, which leads to the failure of the test. You can choose to replace the earplugs with the appropriate size.

2, earplug cleaning problem: there is earwax or dirt on the earplug, which leads to the test failure. You can use a soft cloth to clean the earphones and foreign objects, which can improve the test results.
