Instructions for use:

1. After receiving the earphone speaker, first use a multimeter to test the conduction unit to ensure that the speaker is good. During welding, the unit is labeled positive and negative. The marked colors are positive welding positive wire, and unmarked spot welding negative.

2. The soldering iron should not be used for more than three seconds. If the soldering time is too long, it is easy to burn the voice coil leads or directly burn the circuit board, causing the speaker to short-circuit and become silent. Because the speaker is damaged after welding, the shop is not responsible for return.
