Harman Kardon Onyx Studio 4 is rated 4.3 out of 5 by 87.
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 Sonic marvel Just got my Onyx 4. This unit defies the laws of Physics. Amazing bass coming out of it, to the point that I'm asking for less. Anyway, great unit at a league of its own. I mainly listen to jazz. I guess electronic (bass-heavy) music lovers will adore it.

Can I connect my Onyx Mini to my Studio 4?

Asked by: dwith
It's not possible to connect the Onyx Mini to the Onyx Studio 4. Onyx Mini only have dual Wireless sound which only works with an Onyx Mini or Onyx Studio 3. You may only connect the Onyx Studio 4 with an Onyx Studio 4 that has HK Connect.

Is the Onyx 4 at $137 on Amazon real? It is distributed by HK as well. And the price is $300 plus here.

Can I stream music from my NAS with DLNA?

Asked by: Minos
Harman Onyx Studio 4 can only connect to a source that have Bluetooth device and Auxilliary port. The NAS does not have this features so basically it cannot send an audio signal to the speaker. Also, the Onyx Studio 4 is not design to connect to a home network.
