Harman Kardon Onyx Studio 4 is rated 4.2 out of 5 by 103.
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 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!

Rated 5 out of 5 by from I love this Bluetooth speaker! I just purchased one yesterday from Sprint, and I have to say that I'm very surprised by the clear sound & excellent bass that this speaker puts out. It's the best Bluetooth speaker that I've come across. It's portable with a handle too, so that you can take it to the beach with you after a full charge. Superb listening experience!

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.

hello how can i play music from my SD OR HARD DISK WITHOUTH BLOOTH CONNECTION? CAN I USE SERVICE PORT TO CONNECT USB?

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.

Hello, Is it possible to get stereo from a pair of Onyx Studio 4s connecting the aux connector of one of them to the music source?

Asked by: JC Rivas
Unfortunately it cannot do by only connecting one Onyx studio 4 . An alternative that you can do for now would be to connect a splitter from an aux to separate channels between 2 Onyx studio 4s so you can have stereo sound when playing music.

Onyx Studio 4 - Service port? Hi, Is this port only used to charge other devices or what exactly? I would really appreciate if you can tell me what it is used for ! Best regards

Hi! The Service Port on the Onyx Studio 4 is used if there are firmware upgrades on the speaker, or for servicing if the unit is taken for service.

is it possible to connect studio 3's with studio 4's and if so how do you do it ???

Asked by: pops
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 +.
