No change in audio and has no way to see if the on or off, only one button which always says BOOST
The very best speaker booster i have found. It doesn't stop like another booster did and that one was a 4.7.As soon as I. Downloaded the other one first it started stopping. I haven't had one problem with this one. It's the best one.
