With completely wireless earbuds, the rule is: when the battery fails, they have to be disposed of. Not so with the Fairbuds, that allow you to replace batteries in just a few seconds. Combined with a repairable design, the earbuds should therefore have an extremely long lifetime.
Rhythm game enthusiast use wired headphones & kernel+pipewire settings to further reduce latency—as do musicians for recording on playback. Pro gamers use wired peripherals too for inputs & some even go analog for monitors for lower latency. Is it a stretch to say “wireless” is shorthand for “casual”? 🤔
Musicians (at least in studio) tend to use wired for the quality, which just does not exist in wireless. Less a latency thing. Live performers tend to use a monitor (speaker pointed back at them) AFAIK.
