Sensitivity of touch button - way to sensitive, I was bringing up google assistant or pausing music whenever I was adjusting them in the earVolume control - weirdly volume control worked everywhere, except spotify, which was sad There are 3 empty spaces for 3 additional suits.

The Fur is 100% authentic and is very fluffy and pretty. Also not very soft. I think the bases are wimpy and raise a potential failure hazard. Thrilled I hit a stud! As some colours (by other peoples reviews) are not as expected. until it broke.
