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.
I use Guitarix to emulate effects when jamming by myself & the latency matters quite a lot when trying to hear the audio in my in-ear monitors. I couldn’t image using wireless from the bass guitar back to the laptop back to ear buds… would be too much lag to where you wouldn’t be hearing exactly what you are playing & a lot of folks mention using JACK & different kernel parameters for the latency, but I am no expert in these topics.
