Rated 5 out of 5 by from I love this Bluetooth speaker! I just purchased one yesterday from Sprint, and I have to say that I'm very surprised by the clear sound & excellent bass that this speaker puts out. It's the best Bluetooth speaker that I've come across. It's portable with a handle too, so that you can take it to the beach with you after a full charge. Superb listening experience!

Rated 5 out of 5 by from Super loud and DEEP BASS The speaker can get extremely loud. Like really loud. The bass is very clean yet deep, and it keeps up with the rest of the audio, it does not overdo the highs or mids. Utter beauty

How many Onxy 4's can I connect together? I currently have 2 but plan on buying 2 or 3 more if they can all connect together seamlessly.

Is it possible to connect Onyx Studio 4 to a laptop via bluetooth( Windows 7)? My laptop finds the speaker, however it appears as gray on devices and printers and does not play sound. Works fine on my phone though.
