Rated 5 out of 5 by from Excellent Since I received the speaker I havent stopped listening to music. The sound is so clear and the bass is amazing for size of speaker I think. But I find that the quality of sound of the music to begin with must be good to be able to enjoy the speakers full potential. Excellent I love it, take it round the house with me.

Rated 5 out of 5 by from Amazing I got this for birthday present 5 days ago. I have no words. I really love the high quality products, the high quality music. The design, the sound, everything is perfect. Crystal clear highs, very powerful basses. Very detailed soundscape. This is the best in this price range ( in Hungary it's just 200$ ). I have in blue colour, really nice! Fully recommended speaker! :)

I bought ONYX+STUDIO+4 speaker and now I am wondering does this speaker function also in my home at Finland ? at least plug should be different ....

Asked by: Sede17
The power supply for the ONYX STUDIO 4 is set to Auto Volt so you can plug the unit into either a 110v outlet or a 220v outlet without any issues.

Can I connect Onxy 4 with onxy 3

Asked by: Vimal
Unfortunately the Onyx Studio 3 and Onyx Studio 4 are not compatible in terms of speaker connectivity because they have different proprietary features. The Onyx Studio 3 has the Dual Wireless feature which lets a maximum of (2) speakers connect together while the Onyx Studio 4, on the other hand, has the HK Connect+ feature, our newest feature that allows up to a hundred devices with the same feature to connect to each other. In this case you will need 2 studio 4's and pair it together.

Can you pair Onyx Studio 3 speaker and a Onix Studio 4 so you get the stereo effect, or do I need to purchase another Studio 3 instead of 4? Thanks.

Asked by: mkirkeskov
The stereo setup was only recently introduced to the Onyx Studio 4, which is setup through the HK Connect app using two Onyx Studio 4 speakers.

Is there a slot for an sd card & if so, what size is acceptable?

Asked by: sadjam
Currently, Harman Kardon does not have any speakers that have a provision for an SD card slot; this includes the Onyx Studio 4. if you have plans to use our device with an SD card, your audio device must be SD-card and Bluetooth-speaker compatible.

Can I stream music from my pioneer Bluetooth-able system  to use these as rear surround sound speakers? I’m in an apartment and can’t wire rear speakers.  

Asked by: Porge
It would depend if your Pioneer system is able to connect to the Onyx studio 4 and designate it as a rear surround speaker , If your Pioneer system can do that then it would be no problem.

Good day. Where do I download the Harman Kardon Onyx Studio driver software for Windows 7? Regards

Asked by: Banzi
Any drivers or updates for the Onyx Studio 4 can be downloaded from the HK Connect App. If your Windows 7 device supports Bluetooth A2DP 1.3, then no drivers would be necessary, else this is something you can download on Microsoft's website or with the help of the manufacturer of your device. if this did not help, please submit a case request at https://www.harmankardon.com/support-contact.html and the Customer Service Team will be more than happy to assist you.

I just bought this speaker. So i have a few questions. First, should i charge before using it? Second, how many hours are needed to be fully charged when it is run out of charge?

Asked by: Eray2k
We would recommend that you drain the initial factory charge, then charge it overnight or for at least 5 hours.
