Beats Solo 4

[techtouch]

Hi,

I'm a laptop engineer by trade but a family member brought me a pair of Beats Solo 4's to have a look at as one side wasn't working. After a few checks and happy enough it wasn't anything to do with pairing settings and hard resetted them and issue still there I took them apart.

Hoping I would find a severed wire or bad connection I wasn't so lucky so I checked for continuity from all wires from the main board to the faulty side and found there to be no issues so thought the speaker itself must be faulty...however, after splitting the red wire that connects to to speaker i was left with the red and blue wires inside it and checking continuity between the red wire connection on the speaker and the same wire on the other side i started to get interference through the speaker. I then soldered a 0.1mm copper wire from both those points and it started working??? Not sure what is going on as I checked again and there is still continuity between these wires but it takes the copper wire to be soldered for the speaker to work. I would just run the copper wire to the other side but the headband might be superglued or something as it doesn't want to part.

Anyone any ideas?

Thanks for your time reading this!

You can re-solder and re-tin the existing red/blue wires at both ends with flux, ensuring a solid joint with the enamel fully removed.

It sounds like the apparent continuity was via the blue wire, speaker and amp output, rather than actually via the red wire?
