great value for money

Tracy B.

I like it. It is easy to use. I wish it was a little louder, I do wood working and it is a little hard to hear a lot of the time. I understand, it would use more battery power but I could have charged it more often. Otherwise, it is great.

Love it ! It’s insane how much sound this tiny form factor manages to put out. Great build quality and really good materials .


awesome. thank you!

Handy, great battery life, easy to sync with other speakers in a multiroom setting. And the sound is top notch!


The Addon C3 is easy to set up and use. I am very happy with the sound quality and am not surprised by this due to Audio Pro’s reputation. I ended buying two C3s to produce a stereo effect. I also bought the C-subwoofer to use with the two speakers wirelessly. I am very pleased with how good this system makes my music sound with excellent highs, mids, and lows. I would highly recommend anything made by Audio Pro.
