Internal Lithium-Ion Polymer Battery
The Beats Studio Pro requires a minimum voltage threshold to initialize its internal DAC for USB-C audio. If the internal battery has suffered chemical exhaustion or high internal resistance, the power management system will block the boot sequence of the audio processor even when plugged into a power source. Replacing the battery restores the stable voltage rail necessary for the firmware to execute its power-on self-test and enable the USB-C data handshake.

USB-C Port Daughterboard
Mechanical fatigue on the USB-C port pins can lead to a failure in the CC1/CC2 (Configuration Channel) pins, which are essential for the Power Delivery handshake. If these pins cannot communicate with the host device, the headphones will not pull the necessary current to power the DAC or recognize the digital audio stream, resulting in a 'not working' state in wired mode.

Main Logic PCBA
If the battery and port are functional, the failure lies in the SoC (System on Chip) or the dedicated DAC chip. Thermal stress or electrostatic discharge (ESD) through the charging port can damage the integrated circuits responsible for digital-to-analog conversion, rendering the USB-C audio path permanently non-functional.
