A:AnswerYou can use the plus minus buttons on the top of the speaker or use the Bose app remotely. I’m using an iPad to play music and it can control the volume as well.
A:AnswerNo. Bose has a useless app they want you to diwnload w/ extremely poor reviews, claiming you can link 2 speakers to party mode. Almost every review states once party mode was attemptedn it either doesn't work or the reviewer can no longer use either soeaker. Buy a different brand.
