Nice design, easy connection and set-up and most of all good powerful sound… we’ll see in practice how long battery is lasting but feeling is really good.

Rui Silva

Really nice portable and multi-room speaker with amazing design (it really looks good). I’m still experimenting, but so far the sound quality is great. I’m enjoying it so much that I’ll probably buy the AudioPro Link 1 to my legacy system to make it compatible with multi-room.

Alessio Boschet

Audio is great, i got also a C10 and really it rocks. I suggest an improve to audio pro app. To pair speakers is so slow, and it should be possible to save different pre-made sets, (Like house or living room) for speaker.

I love it! Great sound and easy to use!


Excellent sound and functionality!

Peter Koch

Cute, flexible, with a great overall sound but sound profile could be more even with less depths (like his bigger brother C10).

Veselin M.

Excellent Sound. Great quality. You may work on Android app little more (in part – play music from phone). And i waiting for addon C5 with battery. 🙂


I am very happy with my new C3, it is even better than I expected, cute, small, very good sound… I would like to add a C5 and a C-Sub soon.
