Rated 5 out of 5 by from Fits the bill perfectly. I bought this for one thing only...to lay in bed or hang out on the sofa while watching/listening to stuff (usually You Tube music vids) on my iPad Air which has a pretty crummy speaker in it. Obviously, I wanted wireless capability 1st and foremost with portability a secondary consideration. Good sound, ease of operation, good looks and ruggedness would be icing on the cake. I powered it up 24 hours ago and could not be more pleased. Great sound, huge volume and paired quickly without a bunch of drama to my device (once I figured out how to do this...I’m a techno Luddite). Obviously too early to report on battery life, ruggedness, etc but so far, I’m thrilled with this purchase. My only complaint is HK could have included at least SOME (call it Device Pairing 101) documentation for us Luddites. Eventually, I found what I needed on the HK site but it was REALLY buried!

Rated 5 out of 5 by from Sound stopped working I had this speaker since January and I used it mostly everyday, but yesterday i decided not to use it and I go and turn it today and the sound isn’t working, everything else work so fine but the sound

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 5 out of 5 by from Great Sound! This speaker sounds great and has tons of base! The white color looks so classy too! The only problem is that the app doesn't work on my phone, keeps telling me to pair it when it already is.

I purchased four onyx studio 4 and have misplaced the manuals. please advise on how to pair them all together?

Asked by: Latarsha
To take advantage of the HK Connect + feature for the Onyx Studio 4's, play music on one of your HK speakers and then press the HK Connect+ button (located on top panel) on all desired speakers to start pairing. All the other HK speakers will play same music from the music source. You can also download the Quick Start Guide on the link below, scroll down to Specs and click on the Manuals and Downloads tab:  https://www.harmankardon.com/bluetooth-speakers/ONYX+STUDIO+4.html

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.

What is the difference between the Onyx Studio 3 & 4 ? And can you pair up ?

Asked by: sirlaughalot
Hi, Thank you for your question. Onyx Studio 3 has a technology called HK Connect, where you can pair two Onyx Studio 3 together for party mode. The Onyx Studio 4 features HK Connect+, where you can pair up to 100+ Onyx Studio 4 speakers together or connect with two speakers for the powerful stereo mode. You are not able to pair Onyx Studio 3 with Onyx Studio 4 or vice versa since they feature a different Connect technology.
