JBL Tune 520BT: Is there a reason my headphones keep turning on and off?

Mon, 06 Apr 2026 19:13:46 -0700

My head phones keep turning off when I put them on funny or angle them in some other way, and I think they might also not be sending the battery info properly sometimes. How would I get this fixed? If all else I just need to figure out how to disassemble and reassemble so I can see for myself.

JBL Tune 520BT: No connection between battery and motherboard

Wed, 25 Jun 2025 21:43:38 -0700

Hi!

The battery terminals (BT+ and BT-) on the left speaker read 3.45V, while on the right (B+ and B- I assume?) I get... 0.04V. When a charger is connected the right reads 4V, while the left, well, still 3.45. The red charging light is blinking, the headphones don't boot from the battery (duh).

I assume the connection is broken somewhere in the headband or the hinges, how could I disassemble those? (Is it even possible?)
