You can get them synchronized within 50 microseconds by listening to ssid wifi beacons

You can only sync audio between two esp32 when using AC builds ( AC firmware at the moment no longer supports audio usermod on esp8266 ) .  
To be able to audio sync between esp32 and esp8266 you would have to use MM fork on the slave esp8266 .  
MM and other forks bins are here [WLED installation (wled-install.github.io)](https://wled-install.github.io/)

MM Source is here [GitHub - MoonModules/WLED: Control WS2812B and many more types of digital RGB LEDs with an ESP8266 or ESP32 over WiFi! MoonModules adds features on top of upstream.](https://github.com/MoonModules/WLED)

I have tested that multiple times and it worked but please test it as I no longer use any esp8266 other then for testing
