Onyx Studio is rated 4.7 out of 5 by 67.
Rated 5 out of 5 by from Love the sound and size I love this speakers sound! But the battery life isnt that great so I just leave it plugged in at the shop. I'm going to look into a portable Harman Kardon speaker for the lake and things like that because the sound quality is premium.

I completely enjoy BOTH of my Onyx Studio speakers and take them everywhere. Unfortunately they take some abuse and I have broken 3 of the 4 legs. Can I get replacement legs?

My Onyx Studio will not connect to my laptop. When it trys to install drivers it says they cant be found. I've tried to find them with no luck. Any help would be appreciated.

Asked by: RGusky
The HK Onyx Studio is a plug and play device which does not require a driver. If you are encountering issues then you will need to update your computer drivers so you will be able to connect to your HK Onyx Studio.

So how will a aux splitter work do your techs understand the publics question because they cant seem to answer. I have a onyx 1 and a onyx3 is there a way to play music on both speakers at the same time with one device?

Asked by: valley 1
With the ONYX STUDIO (called as ONYX STUDIO 1) is in the equation, this would not be possible. The ONYX STUDIO does not have an auxiliary port that the splitter can be connected to.
