Bluetooth headphone DAC
An ESP32 and ES8388 audio-board experiment for using wired headphones wirelessly.

The problem
Many devices no longer have a headphone jack, while good wired headphones still work.
What I built
I explored a compact wireless audio board around an ESP32 and ES8388 codec.
What I learned
Audio hardware needs measured performance, not just a signal at the output.
What’s next
Verify the final board revision and publish measurements before calling it complete.
