volume will damage the earphone
2. Earphone is not allowed to contact with strong magnetism, otherwise the
permanent magnet will lose its magnetism, thus will reduce the earphone
sensitivity and affect the sound quality
3. Avoid dropping or hitting the earphone
4. The diameter and length of the earphone connector should match with the port
of the socket, the connector should be inserted into the earphone socket of the
devices such as mixer console, amplifier, PC, etc. Misplug may cause damage
