As shown in the above figure, the length of the speaker wire and battery wire has not been modified. The battery wire is evenly twisted (can be twisted 2-3 times), and the speaker wire is not processed. The two sets of wires need to be placed separately. The excess part of the battery wire and speaker wire should be placed at the edge of the shell (marked in red circle), and do not put too many speaker wires and battery wires into the wire slot! The left and right ears are the same. 3. As shown in the above figure, stick EV cotton near the speaker line of the battery to fix the speaker line, the left and right ears are the same! 4. As shown in Note 1 of the above figure, the size of the foam plug at the cable slot, the position of the plug, and the degree of downward pressure need to be consistent, otherwise there is a risk of frequency deviation consistency, just like the left and right ears! 5. As shown in Note 2 of the above figure, after pressing the speaker wire to the bottom, fix it with glue, and the left and right ears are the same! 9 V：Structure file
