    • Excellent Speaker! Better Than the Onyx Studio 8!
Color: Black
Overall this is a great speaker! The only problem I have with it is after a couple of years the battery dies and needs replacing. The problem with this is that there is no battery with the same exact power ratings available and the battery that is being sold as its replacement is not the same battery. This replacement battery died permanently after a couple of months. It was also prone to shutting the speaker off while playing at maximum volume. The battery also had a shorter lifespan while actively playing at high volume. The original speaker and battery are excellent just don't think doing a battery replacement is going to fix the dead battery issue. ... show more

    • Way better than JBL or others
Color: Black
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. ... show more

    • ONYX STUDIO 7 SUPERB

The media could not be loaded. 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 INSTRUCTIONS 1. 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 ! ... show more

    • Exceptional sound quality, with some cons
Color: Black
PROS - Above average sound quality for the price - Attractive design and fixed the degraded rubber rear - Auxiliary audio input - 19VDC power input allows you to connect external power bank - More power than the previous model - Allows you to connect two units of the same model to increase stereo effect CONS - Insignificant internal battery, and it loses sound power when it is in use, but you can connect an external battery! - Bluetooth a little buggy sometimes BOTTOM LINE - The Onyx Studio 8 model is rumored to come with an internal power supply. If this is confirmed, it will be more complicated to use an external battery, and if they do not improve the internal battery, this could mean a setback, so the Onyx Studio 7 model can be a great advantage, since normally the sound power does not change between generations very quickly. ... show more

    • Love the bass
Color: Black
The media could not be loaded. Connects fast, easy to use, quality is fire and love the appearance of it as well. Can use it without the cord for a short period of time before it dies and great portability with the handle.
