thats pretty neat, nice to have so you can replace the battery if it ever dies (dies as in doesnt charge anymore)Grabbed some pretty neat earbuds!
The detachable magnetic stalks are actually the batteries, and the case charges two for you while you're using them. Loved the idea of hot swapping batteries since I grabbed SteelSeries' Arctis Nova Pro, so good to see it implemented on other stuff.
but im skepticle on the quality at a cost of $7.60, both build and sound
most name brand earbuds usually have 20-30 hours battery life (6-11 on the earbuds themselves, and usually 2 or more charges from the case), never really found it an issue of it dying, and they usually support a quick charge
