Excellent sound quality and very simple to install. If you are already using optical port than order a splitter box and extra cable. Sounds complicated but really just takes minutes to install. Instructions are simple. I've been using system plugged into wall power so haven't evaluated system on battery power. Also use my own headphones rather then ear buds that come with the system
positive
