Harman Kardon Onyx Studio 4 is rated 4.1 out of 5 by 118.
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 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 Earlier Onyx Studio Purchased an earlier Onyx Studio at a SPRINT store. As I walked in to the store(approx. 1200 sq ft), music was playing quite loud and I thought that the sound was coming from the store's sound system. The music filled the store with rich bass, not the thump, thump that you commonly hear from this type of speaker. What was even better was that it was on sale due to packaging damage! Should have purchased 2!

Good day. Does the Studio 4 have Aux input?

Asked by: JeanLambrechts
Yes they do. The Onyx studio 4 has an Aux input in case the source device is not capable of connecting to it via Bluetooth.

hi, i dont find the pin number to conect to my pc

Asked by: zipo68
There's no pin code required for the HK Onyx Studio 4 when pairing it with any Bluetooth-enabled audio source device. It would normally be the source that is requesting for the pin. Try entering "0000," "1111" or "1234" when your device asks for a PIN. These are some of the most common default Bluetooth PINs.

Hi, I would like to connect an onyx studio 3 to a onyx studio 4 and still can not do it. Could you guide me on how to do this?

Asked by: AmirB
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 OnyxStudio 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.

I have bought an onyx studio 4, and its sound is great. noted the speaker has AC mode, can i keep it on my desk and remain it plugged in as i dont plan to move it around my home? will this affect the battery inside? thanks! best regards, Philip

Asked by: Philip Leung
There is no harm in leaving your Harman portable product connected to electricity at all times. You can simply pick it up, unplug it from the charger and be on your way, knowing that you have a full charge.  However, if you’d like to conserve electrical energy, disconnect from charging. It will not overcharge.
