Harman Kardon Onyx Studio 4 is rated out of 5 by 216.
Rated 5 out of 5 by ShoneBT 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 ShellyM954 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 Jakub 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 BobJ 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 Trevor 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 Clit2ras 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 Shone 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 Anonymous 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! :)

Why my hk onyx 4 not make any sound when i connect it to my laptop unless I connect it too with the cellphone? But, when i just play music from my cellphone that speaker works well. is it problem with my laptop driver or my speaker?
Hello! The Onyx Studio 4 utilizes the standard Bluetooth Stereo Audio drivers available in most laptops. There are two different Bluetooth protocols, one for Headset Audio used for talking on the telephone, and the other for high quality stereo audio listening. Being that the Onyx Studio 4 is a speaker; your computer must connect to the speaker using the Stereo Audio protocol. Your best bet is to go into your control panel and find the Bluetooth setup. This setup usually provides a setup wizard and will take you through the steps to install the drivers needed for Stereo Audio.

Can I remotely turn the Onyx 4 on and off? Possibly using HK or similar iOS app, or a smart plug, smart switch, Amazon Dot Echo, etc?
Unfortunately the Onyx Studio 4 can only be turned on/off using the power button on the unit itself.

Whats the difference between Onyx 4 and Onyx 5 other than portability? Is the sound different? Louder? Richer?
The Harman Kardon Onyx Studio 5 and Onyx Studio 4 has the same frequency response of 50Hz-20kHz (-6dB). However, the Onyx Studio 4 would be able to play more and clearer being that it has 2 woofers and 2 tweeters rated at 15W each, while the Onyx Studio 5 only has 1 woofer rated at 50W and 1 tweeter.

Can I use the dual sound and pair the 4 and the 4?
The Onyx studio 4 does not have the wireless dual sound but it has the HK Connect + that lets it connect to up to 100 speakers or more with the same feature. So you can connect multiple Onyx Studio 4 at the same time.

If I have a unit of HK Onyx 3, will I be able to pair it with Onyx 4?
The Onyx Studio 3 could not be paired to the Onyx Studio 4 because they have a different connectivity feature. The Onyx Studio 3 will only pair to same model via Bluetooth while the Onyx Studio 4 will connect to another Onyx 4 via HK Connect+.

Hi, is het mogelijk om meerdere onyx 4 met een go + play te koppelen (pairen)?
Hi, Nee, je kan de Onyx Studio 4 niet met een Go+Play koppelen. De Onyx Studio 4 heeft HK Connect+, een technologie welke niet in de Go+Play zit. Wel kan je de Onyx Studio 4 met andere Connect+ apparaten koppelen, waaronder ook de JBL Connect+ speakers.
