Any adjustments you make can easily be done with the few buttons or the volume knob. There are no complicated switches.
Pro Designed for use away from home
It's lightweight and portable to stash in your diaper bag. Having a battery operated option gives you flexibility to travel without worrying if there will be a conveniently placed outlet or not.
