Synchronize 25 ESP8266 to start playback of an audio file at the same time
This is a perfect use case for MQTT, e.g. this library for ESP boards. Create a broker on the network (e.g. a Raspberry Pi running Mosquitto, and have all the ESP boards subscribe to a topic. When you want to play a sound, publish a message to the topic, and all of the ESPs should see it very quickly. You don't need to synchronize clocks any more because it's simply based on the timing of publishing a message.

Is there a lowish consistent wireless method for sending variables to an esp32?
For ESPs, the library EspMQTTClient makes it incredibly easy to manage Wifi and MQTT together (with reconnect, OTA, etc)

ESP network | ESP NOW | MQTT on RPi
I actually hadn't heard of ESP-Now before but it seems like a nice solution to get quite a bit more range without using LoRaWan. When I was researching it a bit more I came across this guy who I believe has exactly what you need: https://github.com/jonasbystrom/ESP-Now-Sensor-system-with-WiFi
