## Customer Reviews

### ⭐⭐⭐⭐⭐ Great for $165 on when it was on sale.
*by  on Reviewed in the United States August 16, 2026*

Sound quality is absolutely stellar, for the price below $200 it was an absolute steal of a deal. Though this thing eats power like crazy so maybe have it near a plug or power supply.

### ⭐⭐⭐⭐⭐ Way better than JBL or others
*by  on Reviewed in the United States August 11, 2022*

Really glad I went with this option instead of spending about the same on a JBL or other popular brand. The sound quality difference is impressive, because of it's dedicated speakers. It sounds about the same or better than the $400+ Bose Portable Smart Speaker or Sonos Move. I tried them out to compare and it's the best in my opinion. Can't even compare this to JBL or the numerous other bluetooth speakers, even their high end models, this thing is way better.At the price point this is at right now, it is less than half the cost of what it's worth. It can be a bit confusing, with there being an Onyx 6, Onyx 4, etc - I just went with the Onyx 7 after researching a bit and I am glad I did. The Onyx 6 is very similar, just a very slight different sound. I think you'd be good with either and can choose more on looks in my opinon.The battery life advertises at 8hr, but surprisingly it has been 10 hours now and it was still working before I turned it off. We had it at about half volume (which is plenty loud) which might be why. It has a dedicated charger which is maybe a negative, but not a big deal.Great build quality, hefty without being too much to carry around.The packaging and charger quality is pretty impressive, they put some thought and effort into this.Have to give it to Harman Kardon, you aren't just buying a gimmicky name or something with this thing. Sure, it isn't audiophile grade $1000+ speakers, but it's the best speaker in this form factor in my opinion.

### ⭐⭐⭐⭐⭐ ONYX STUDIO 7 SUPERB
*by  on Reviewed in the United States April 10, 2022*

Now I bought the second speaker on Amazon . The first speaker I got at T-Mobile when I went to get a new iPhone and I just heard the sound quality and added it to the bill . I have JBL speakers a duo and a sub woofer that I use with a docking station that uses the old iPhone and it just packed up, and I was so distraught . The speakers are a collectible , huge and I love them ! So I needed a blue tooth alternative as the old docking station uses the old iPhone base, and it is no longer sold . Long short of it I now have 2 speakers. The pairing was tricky, but for a 1 minute pairing, do this as no one addresses that on reviews . PAIRING INSTRUCTIONS1. Get your pairing device ready: Once you have the two speakers close to you, you can then turn on one of the speakers. On your mobile device, navigate to Bluetooth and turn it on, then pair the phone with one of the Harman Kardon Onyx speakers that you have turned on. Once it is successfully paired with the speaker, you can then turn on the other speaker.2. Use the connect + feature: All you need to do is to simultaneously press and hold the Connect + buttons or Bluetooth buttons on the 2 speakers for at least 7 seconds. The LED light on the two speakers should blink white very quickly if the speakers have been paired successfully.3. The Bluetooth buttons pressed simultaneously does the magic in a second and they are paired !!!!4. Enjoy great sound: Once you have successfully paired the 2 Harman Kardon Onyx speakers, you can then begin to enjoy quality sound production.You all are welcome and Harman Kardon Rocks !
