Harman Kardon Onyx Studio 4 is rated 4.2 out of 5 by 215.
Rated 5 out of 5 by from Superb! Update! After 8 months of having a pair of Onix 4's I am even more delighted than I was when I bought first one! If you plan to buy a home hi-fi without breaking a bank, my advice is to buy these. Position them as far away from the wall (to reduce not so controlled bass), remove the grills (to gain 1db in hf range), use app to pair them in stereo mode (for soundstage), tilt them (like studio monitors for imaging) and keep those tweeters at ear level (for detailed sound)... You won't believe what sound quality these bt speakers can produce. Now at 360 USD for a pair (in Europe), I can't find anything even close... Pure madness!

Rated 5 out of 5 by from Awesome Speaker My hubby bought this speaker just to try it out (we usually get Bose), after I suggested he try Harman Kardon since they made speakers for some Mercedes Benz models. This speaker delivers awesome sound quality. The bass is crazy!! (And I mean the good crazy) My sons love it so much they're purchasing their own. I also love that more than one person can connect to the bluetooth at one time, and that you can sync several of these together. Imagine having a party with these babies!! I'm very happy with this purchase. Glad we bought it. Now to try out the headphones.

Rated 2 out of 5 by from Poor Bluetooth connectivity Great audio quality, but poor Bluetooth connectivity. This speaker just support SBC Bluetooth codec, does not support any high quality codecs. To get battery level (on android or apple), you must install HK app, share location, and wait 10 seconds for it to sync, because it creates a separate LE connection for just that. Can you please fix that ? Either implement HFP1.7, or the Apple "Bluetooth Headset Battery Level Indication". If you can't do that, at least use standard LE "Battery Service" rather than custom notification. Please fix the battery level in next firmware update.

Rated 5 out of 5 by from If they could correct battery/charging issues... These would be best in class, period! One "solution" I found for the battery endurance issue was to buy a 20,000 mAh power bank that is capable of 19v output. The one I bought comes with several different size adapters that will plug into the OS4. Power conversion will eat a fair amount of power (unavoidable for ANY power bank), but what is left allows me to run the speaker at full volume for no less than 5 hours! It is as if the speaker were plugged into the wall electrical outlet.

Rated 5 out of 5 by from The Best Bluetooth Speaker No other bluetooth speaker can compare to this masterpiece, perfect sound quality and with the easy link to other speakers, you can create easy surround sound. It's got a price tag, but the bang is worth the buck. The only problems I've experienced is an every once in a while skipping type sound. It's not my music I think, but I'm going to look into it. The speaker is still worth it overall, as I said, literally nothing can compare to this speaker.

Rated 5 out of 5 by from White 4 looks great I've got onxy 2 3 4 all sounds the same and looks identical look out for 5 next year it will do the same just a name change and price hype so by earlier model when price will be massively reduced. Also brought two sound sticks 111 one come with Bluetooth acsess and other one only works with RAC jack lead same price so be careful when dealing with online shop but still a great product be careful you don't get stitched up.

Rated 5 out of 5 by from Great mid-range bt speaker! In Europe is priced at 200 euros and it's hard to find anything better in that price range. Balancing it with some eq is a must, otherwise bass is way too overwhelming, mids are recessed and highs are not well pronounced... But when you play with it for a few days, man it shines! Nice sound stage, punchy bass, good mids, solid highs and even some stereo separation... Planing to buy another one these days. That should be impressive!

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! :)

Hej. Jeg har to Onyx 3 som er blevet brugt i samme stue og fungerer fint. Nu vil vi gerne dele dem op.... Men vi har problemer med at parre dem med hver deres Uni (ipad, mobil etc) Der er som om den ene "bestemmer" og tager lyder hver gang....

Asked by: KlausD
Hej Klaus, Tak for dit spørgsmål. Det kan være de begge to er forbundet sammen via Dual-sound forbindelsen. Prøv at gendanne fabriks instillinger på dine højtalere ved at gøre følgende: Press and hold the Phone and VOL + button simultaneously when the product is ON. After 5 seconds, the unit powers Off, and is now reset. Så kan du forbinde via Bluetooth igen til hver sin højtalere da den sletter alle andre Bluetooth forbindelser. Husk at gøre dette på dem begge to. Hvis det ikke hjælper så kontakt vores kundeservice på customer.support@harman.com

Hi I am planing to purchase 2 of them, put them on pair mode and listen to my laptop. Is it possible witouth HK mobile app? Can i listen thru 3.5mm jack? If yes, i will use only one jack for both speakers?

Asked by: Ggg7
The pairing mode of 2 Harman Kardon Onyx Studio 4 is only possible through the HK Mobile app if you mean to do it wirelessly. But you can connect a 3.5mm splitter cable to your laptop and connect the speakers with audio cables on each end to get them to play together. You would, however, only be able to get a mono-stereo sound this way.

Can I stream music from padora on my iPad to this speaker?

Yes, you can. There should be no problem streaming music from Pandora or any music app from your phone thru the Harman Kardon Onyx Studio 4, as long it's connected to the speaker via Bluetooth.

Can I use the dual sound and pair the 3 and the 4? Just bought the 4 to pair with my 3 and can't get them to connect

Asked by: Miller
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. 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.

Hej,  Har precis köpt min onyx 4, super nöjd. Dock undrar jag om det är möjligt att sänka basen? Kan ibland uppleva att den är lite för tung för min smak! 

Asked by: Mmmmharmon
Hej, og tak for at du købte Harman Kardon! Du kan ikke regulere bas-niveau på din højttaler, da der ikke er nogen toneregulering af nogen art. Det du kan gøre, er at regulere frekvensgangen på din signalkilde. Hvordan du gør det, afhænger jo af, hvilken kilde du benytter. Hvis det er en mobiltelefon, er problemet uhyre simpelt at løse: du tjekker først at de equalizere, som næsten alle mobiltelefoner har gemt et eller andet sted, ikke er sat på bas-boost. Dernæst bruger du den indbyggede equalizer til at reducere bassen, eller du henter en af de mange, gratis eq-apps, som kan gøre det samme. Problemet løst! Husk dog også, at den fysiske opstilling af din højttaler er meget vigtig! Hvis du placerer den helt frit på et gulv, langt fra vægge, eller måske endda på en lille stol eller reol midt i rummet, får du mindst bas, da der ikke sker nogen akustisk forstærkning af bassen. Hver gang du kommer nærmere til en stor flade, vil bassen stige med 3dB. Det betyder, at placerer du din højttaler på gulvet, helt inde i et hjørne, får du en massiv forstærkning af bassen. Hvis du nu bevæger højttaleren bort fra hjørnet, synker basniveauet gradvist. Jeg håber, dette hjælper.

Can I use this speaker as a surround sound for my television? 

Asked by: CHRIS8455
We would suggest using a true home theater system with surround sound since these speakers can only do Stereo and not a complete surround sound system.

Skiller højtaleren automatisk? Kan jeg feks sætte en chromecast audio i aux porten og spille derfra uden at skulle tænde for højtaleren hver gang?

Asked by: anto1725
Hej, Tak for dit spørgsmål. Desværre, sådan er højtaleren ikke designet og når den er gået i standby eller "off" mode, så skal man trykke på power for at den vil reagere på Chromecast via AUX kabel.
