Harman Kardon Onyx Studio 4 is rated 4.2 out of 5 by 29.
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! :)

Rated 5 out of 5 by from Earlier Onyx Studio Purchased an earlier Onyx Studio at a SPRINT store. As I walked in to the store(approx. 1200 sq ft), music was playing quite loud and I thought that the sound was coming from the store's sound system. The music filled the store with rich bass, not the thump, thump that you commonly hear from this type of speaker. What was even better was that it was on sale due to packaging damage! Should have purchased 2!

Rated 5 out of 5 by from best portable sound there is I've bought it 2 weeks ago after listening to my friends Onyx2 and fell in love with it. Previously I've owned some smaller portables (Bose Soundlink2 and other) which didn't provide the clarity of sound or the oomph that this one gives just fine. The only down side I could point out is its portability. Yes, you can move it between rooms or take it out to the garden, but taking it to the park or the beach doesn't seem to be the best idea.

Rated 5 out of 5 by from Great durable speaker! For a long time I was buying cheap speakers here and there, but my sister and I decided to buy two of these and ITS amazing for when we have parties at our house, track meets, and so much more! 10 out of 10 highly recommend

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.

How do you pair 2 speakers to each other? Please share in detail.

Asked by: chgl
The pairing process is done through the HK Connect App. This is available through the Google Play store and App store. This is where you can setup multiple speakers under Party Mode, and a maximum of two speakers for Stereo Mode.

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.

how do i know the percentage of the battery while im using it? there is no battery led indicator for onyx 4?

Asked by: jokher
Actually there is no battery indicator for our Onyx Series but you may be able to notice that the RED light will blink on the power button if your Onyx Studio 4 is in low battery.

Can i pair the onyx studio 3 with the studio 4? or do i need two studio 4s

Asked by: mylesjjj
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.
