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! :)

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.

Can i use 220V power supply with the onyx 4?

Asked by: jdm2
Yes, you can safely use the Onyx Studio 4 on a 220V power supply, since it has a power supply cable that is capable from 100V-240V.

I want to purchase two Studio 4s and use them in stereo mode. If I turn them off and then turn them back will they automatically be in stereo mode again or will I need to reconnect them in stereo mode every time I turn them on?

Asked by: Curious Tim
No need to reconnect them in stereo mode as once they're turned off and turned back on again it will still play in stereo mode. If you want to change it back to party mode, you will need to change the setting on the HK Connect+ app.

1. if connected to power 24h 7days, is it ok? i want to use it as a pc speaker. will battery charging stop automatically and work as if non-portable speaker? 2. can two onyx4 work as stereo from pc(not smart device)?

Asked by: donuts
It is safe to have the speaker connected to an electrical outlet 24/7, however this is not what a portable speaker is designed for. We have comparable speakers that are not portable and have to be connected to an electrical source for use. The stereo mode is only available through the HK Connect App.

Are the foot pegs (little legs on the back) removable? I want to be able to carry the speaker in a slim-fit bag but the pegs would appear to be in the way. Thank you.

Asked by: Shawn1
Unfortunately the legs cannot be removed as these are designed for Home use.

Asked by: Shaq
I have the same problem with 2 new onyx 4, I have connected the jack 3.5 from PC output. I've also used youtube from my phone, but the same latency. If I unpair them, the sound from my PC is OK (on a single item), ... I am not able to have stereo on both :(. Please make the fix public because I think the issue is common.
