Harman Kardon Onyx Studio 4 is rated 4.3 out of 5 by 157.
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 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! :)

Rated 5 out of 5 by from Great speaker Sound is great! After testing a lot of other models I can tell, best sound quality for its category. Two improvements needed, add micro usb or even better usb-c to charge with any charger. And secondly, improve integration with iOS devices to display remaining battery percentage.

how do i play both studio speakers at same time

Asked by: Mmmcniel
Hi! To connect one Onyx Studio 4 to another one to play at the same time, first is there should be a source already connected to one of them. While playing audio, press the HK Connect+ button on both speakers at the same time, and wait for them to pair with each other. Once done, they will already be playing at the same time. If you would still be experiencing issues after following the steps above, please contact us at https://www.harmankardon.com/support-contact.html and the Customer Service Team will be more than happy to assist you.

Can I leave my Onyx studio 2 speaker turned on all of the time without it wearing out?

Asked by: gregc
Hi! No, the Onyx Studio 2 still uses up battery even it is on standby mode which is why it can still drain the battery at a minimum until it shuts off.

Jeg købte min Onyx Studio 4 for ca. 6 måneder siden, og i går begyndte den at drille mig.  Hverken når jeg tænder eller slukker, kommer der den normale tænd/sluk-lyd, og jeg heller ikke få musik fra telefonen til at spille, selvom den er tilsluttet?

Asked by: SimonCCC
Hej Simon, Tak for dit spørgsmål. Det lyder ikke godt at du har problemer med din Onyx Studio 4 efter så kort tid. Du kan prøve at lave en reset af højtaleren for at se om det kan hjælpe, se nedenfor: Press and hold the Phone and VOL + button simultaneously. After 5 seconds, the unit powers Off, and is now reset. Prøv ligeledes at fjerne den fra din Bluetooth liste på din telefon og genstart din telefon efterfølgende og begynd at forbinde igen til den via Bluetooth. Hvis det ikke virker, så skal du tage kontakt til det sted hvor du har købt højtaleren og forhøre dig med reperation af produktet. Du kan altid kontakte os på customer.support@harman.com for yderlig hjælp.

can i connect an onyx 3 with an onyx 4, how?

Asked by: zach724
Hello! Unfortunately the Onyx studio 4 would not be able to connect to the Onyx Studio 3 since the Onyx Studio 4 has the HK Connect + that allows you to connect to 100+ speakers with the same feature while the Onyx Studio 3 has Dual Sound which is a different technology from the HK Connect +.

Bonjour je viens d'acheter l'enceinte. Il n'y a pas de consigne sur l'utilisation de la batterie. Existe t'il un moyen de savoir lorsque le cycle de charge est complet ? J'imagine qu'il ne faut pas la laisser en permanence sur le secteur. Merci

Asked by: nicow
Bonjour et merci pour votre question. Le temps de charge indicatif de l'enceinte Harman Kardon Onyx Studio 4 est d'environ 5 heures. Le témoin de charge est le clignotement du bouton d'alimentation en blanc. Pour obtenir une assistance personnalisée avec le Service Clientèle Harman, vous pouvez ouvrir un dossier en cliquant sur "Envoyez nous un email" ou sur le lien "Contactez-nous" en bas de la même page.

Asked by: sam k
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.
