Powerbeats 3 won't charge

[djc6]

My pair of Powerbeats 3 no longer charge. I have a USB multimeter attach and it shows the headphones are not drawing any current while charging. Tried cleaning the MicroUSB port with a tiny amt of isopropyl alcohol, tried various reset procedures I found online (hold down power button + volume down button) and I also tried different charging cables, different wall A/C adapters. Any other tips on how I might get them to charge again?

Hmm, I recalled I have some DeoxIT D5 spray - used it on the MicroUSB connector. Now the multimeter claims its drawing 0.03A maybe a sign of life?

well the Powerbeats 3 have been drawing 30 microamps all day and still won't turn on, or draw a meaningful charge to charge the battery.
