Harman Kardon Onyx Studio 4 is rated 4.2 out of 5 by 190.
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! :)

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

Hoi is deze speaker ook te koppelen aan Sonos of aan MHF

Asked by: mb1962
Hi, De Onyx Studio 4 is een Bluetooth speaker, dus als de Sonos of MHF ( wij hebben hier geen technische informatie van ) kunnen koppelen met Bluetooth, en de Bluetooth profielen A2DP en AVRCP ondersteunen, dan zal dit mogelijk moeten zijn.

Can i continuosly plug in the charger while in use for long time?

Asked by: Mardi
Yes, it is completely safe to leave the Onyx Studio 4 connected to the power whether it is in use or not. Take note that using the Onyx Studio 4 while plugged in will prolong the charging time.

Asked by: melvic
Hi! Unfortunately the Onyx Studio 4 may only play audio using Bluetooth and/or AUX. Audio files on a hard drive, SD card, or USB stick would not play using the service port, since it is used only for servicing the speaker.

Kan de Harman Kardon Onyx Studio 4 aan een Nintendo Switch gekoppeld worden? Zo ja, hoe?

Asked by: NintendoSwitch
Hi De Nintendo Switch heeft een hoofdtelefoon uitgang ( 3.5mm jack ), waar je de Onyx Studio 4 aan aan kan sluiten. Het is niet mogelijk de Nintendo Switch via Bluetooth te koppelen, de Bluetooth hardware in de Nintendo switch is gereserveerd voor controllers. Voor meer informatie daarover kan je het beste contact opnemen met Nintendo Support.
