Harman Kardon Onyx Studio 4 is rated 4.4 out of 5 by 53.
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 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 This thing is Amazing I bought this at Best Buy and this thing is amazing. Great sound, super easy to connect and awesome battery life. I am planning to get another one to pair with it for my computer at the home office. I love to play music pretty loud and this thing does the trick!

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.

The HK Connect app is sketchy at best. Sometimes it works, other times it fails to even recognize both speakers, it drops out of the "Stereo" constantly. Any suggestions. Great speaker but this app is less than Harman quality. When it works love it!

Asked by: Clifford K
Please try uninstalling and re-installing the application again. If you continue experiencing the problem after this, please submit a case request at https://www.harmankardon.com/support-contact.html and the Customer Service Team will be more than happy to assist you.

I have one set of Onyx Studio 3's and one set of Onyx Studio 4's, are charging cords identical/interchangeable? In other words can any of charging cords be used on any of the individual speakers? or are there differences?

Asked by: Clifford K
Hi! Yes, the charging cords will work for all of the Onyx Studio speakers--they're all the same.

How do you connect studio 3 to studio 4? One is HK connect and other is Dual Sound connection....so they cant link wirelessly?

Asked by: Justin246
Hello! Unfortunately the Onyx studio 4 would not be able to connect to the OnyxStudio 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 +.
