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! :)

The Harman Kardon Onyx Studio 4 has a Bluetooth receiver and 3.5mm jack. If your Bose radio has a Bluetooth transmitter or Auxiliary Out then yes, you can connect the two.

Hi! Unfortunately, you can't connect any of the Aura line of speakers with an Onyx Studio 4, nor with any of the Onyx line of speakers.

Als ik nou geen Apple of Google Android heb alleen een laptop met Windows 10 Pro, hoe kom ik dan aan een eventuele update van firmware?

Asked by: Sex Pistols
Bedankt voor uw vraag. Voor het uitvoeren van laatste software updates is de HK Connect app nodig via een smartphone/tablet. Automatisch wordt hierin de laatste software update beschikbaar gemaakt en zo niet dan is de speaker al uitgerust met de laatste software. Helaas is dit niet via de PC mogelijk, maar mocht er iets zijn waarvoor u verdere ondersteuning nodig heeft, schroom dan niet om het Harman Customer Support team te contacteren per telefoon, e-mail of chat voor directe hulp. Zie https://www.harmanaudio.nl/support-contact.html voor meer informatie. Dank u.

Hvis jeg vil bruge den som fast Bluetooth højtaler til min Google Home, registrere den så selv at der kommer signal og går igen som omni modellen gør? Eller skal jeg tænde den hver gang jeg vil høre musik? Planen er at strøm adapteren er i konstant....

Asked by: Heyden
Hej Heyden, Jeg tror ikke du kan forbinde den til Google Home via Bluetooth. Hvis du er forbundet med Bluetooth hele tiden med din telefon, så vil den vågne op når der spilles, men er du ikke så skal du over tænde for den. Til det koncept du tænker på, så vil jeg anbefale du kigger på vores Citation serie som har Google Assistant bygget i og du kan let og elegant spille musik via din stemme.
