Mainly because if your ears get hot any sweat can cause the earbuds to fall out. They at least don’t fall on the floor (just into the headphone can) but it’s not as nice as having regular wireless headphones.
Pro-tip: if you plan to use them for more that about 3 hours at a time, get a second pair of earbuds. That way when the first one’s battery dies you can just swap them out while it recharges
I first used XFCE on my old 700mhz processor Thinkpad back in the day. Back then, Gnome and especially KDE were known to use excessive resources on low-end machines so XFCE was preferred.
However, I actually quite liked the DE so I just switched to it permanently, even on my more capable machines. I’ve been running XFCE for around 15 years 😆
