Rated 5 out of 5 by from I bought 3 of these to use HK Link. IMPRESSED I got 3 of these to use the HK Link to try and make a whole home audio setup without the setup of Wifi devices in my remote cabin. The 3 units are in separate rooms and all connect seamlessly and easily together to make a great whole home audio solution. Great job Harman!!

Rated 5 out of 5 by from Amazing sound... Bad app for Stereo mode I've become a Bluetooth speaker junkie and these are wonderful in all areas, execpt two the app to connect stereo mode is a test of patience..plan a extra 15 minutes out of your day ,never seems consistent no matter what divice I'm pairing with and more than half the time the app just keeps closing.. I also wish they had Auto shutoff after a certain amount of time like my Onyx minis do . But other than that the best for home use, get 2,put in stereo mode (eventually), keep them plugged in for extra ummpphh and enjoy ....

Can I connect 2 Onyx Studio 3 with 2 or more Onyx Studio 4?

Asked by: Alexander Munoz
Unfortunately, you would not be able to pair a Harman/Kardon Onyx Studio 3 with an Onyx Studio 4. This is because the Dual Wireless Sound featured in the Onyx Studio 3 only gives you the capability to connect to a second Onyx Studio 3 since the wireless dual sound feature only works on the same model. And the Onyx Studio 4 has a different connect feature called HK Connect that uses an app to connect the speaker to another speaker that has the same feature.
