QearFunStereo 3.5mm In Ear Cat Earphones Earbuds with Microphone With Earphone Storage Case For iPhone Samsung MP3 iPod PC Music (Blue)

It lastes well really good, but sometimes the case breaks(mine didn’t, take care of it)but what happened to mine was that 1 of the earbud doesn’t work

Do they retract?

volume control?

Are they compatabile with the note 8?
