Where manufacturers do not publish updates, communities sometimes step in. Enthusiasts and tinkerers examine firmware images, sniff Bluetooth traffic, and document behavior: Before we discuss firmware, let’s establish the hardware

These investigations occasionally produce unofficial tools or guides: how to force a factory reset, how to interpret LED blink codes, or how to extend usable life with simple behavioral tweaks (e.g., turning off automatic wake-on-voice to save battery).
