Onyx is rated 4.7568 out of 5 by 37.
Rated 3 out of 5 by from Could be better especially regarding price level I was always a big fan of Harman Kardon and JBL Products. I owned several versions of the go&play as well as the old JBL Radial which put out an impressive sound for its size. As I love portable speakers and small speakers with big sound I directly bought the Onyx when it became available as it looked like a serious contender in the already crowded market with brands like Bose, Jawbone, Logitech etc. I was sure Harman would manage a more serious sound from a small enclosure like this. The reality is that the speaker sounds impressive, but only in a particular volume-frame. Listen to it at lower volumes (below 35%) and it sounds rather flat, not really better than my much smaller Bose Soundlink Mini. The Onyx needs volume and it starts to really sound serious up from about 50% to 70%. The bass pumps quite nicely and treble and mids are in harmony allthogether. It is only at levels above 70% where bass starts to fade and mids become a bit dominant making the speaker sound harsh with added distortion, but we are already talking about really high levels, much higher than other portable speakers are able to reach (like the Bose Soundlink, or the BIG Jambox). I am only underwhelmed by the fact, that Harman didn't manage to tune the DSP bettter for all levels. Trying to listen to the Onyx for low background music it only manages to sound like a better kitchen-radio. I really love the design of the speaker. But it is not perfect for portable use. Despite having an internal rechargeable battery, i wouldn't like to carry the speaker around to the beach etc. The handle should have been made rotateable, so that you can rotate it flat with the spaker to make the speaker thinner for transport. But still the leather at the back and the exposed aluminium surface of the passive radiator are prone to be damaged or scratched during transport. One would need some special bag or something to better protect the speaker, a pity none is included for the given price. Connectivity is great, i can use the speaker either in my Airplay-setup, or as DLNA-player or simply as a bluetooth speaker. No other speaker i owned so far had such a broad connectivity. The App is nice, but it doesn't give you much more options for tuning the speaker. I hoped for an additional EQ or a loudness-setting, but you can only add a "stereo widening" feature, which doesn't harm the sound much, but doesn't really broaden it up either. The Onyx still sounds like a mono-speaker, except if listening to it really close. All together i expected more for the given price and I am probably going to send the speaker back. The design and materials are top-quality, but i question why the back-surface had to be made of leather as normally you wouldn't notice it most of the time. The most annoying fact is that you really have to crank the speaker to get the best out of it. It is not really suitable for lower volumes. I only hope Harman takes the product serious and adds some other features (like loudness, customizable EQ etc) for future firmware updates.

Rated 5 out of 5 by from Exceeds all expectations You must hear this speaker in an outside environment to fully appreciate its capabilities. Of coarse, inside the speaker is spectacular, but when placed in a open area, fifty feet from the listeners, the speaker continues to belt out full rich sound with plenty of base. In addition, the setup on a home network as an airplay speaker is a snap, only taking a couple of minutes. In short, this beautiful object exceeds all expectations.

Rated 5 out of 5 by from amazing sound I got this a month ago and use it all the time. The sound is amazing on it and gets pretty loud. Easy to use, stand looks nice and has a nice handle to hold it.

Rated 5 out of 5 by from awesome product I bought this item at a sprint store as a promotion. even though it was deeply discounted, i hardly pay over $200 for any speakers that wouldn't work for my djing company, but, i have to be honest, i was blown away by these speakers. I have a JBL Flip that has a great sound, but is missing a lower bass frequency. The Onyx more than makes up for that missing low frequency, plus its wireless.

Rated 5 out of 5 by from FINALLY !!! I've had my Onyx for 3 weeks now, still amazed every time I turn it on. I've tried just about everything out there, Big Jambox was the biggest sound I found.  First saw this back in the fall and knew it was THE ONE. I was right. This speaker is amazing. The sound is exceptional at any volume level, and cranked up the bass feels like its going through you. It's a new level of sound for Bluetooth portable speakers. It is rather large to be very portable, but who cares? It's the sound that matters!! So I say skip everything else and spring for this, worth every cent.

Rated 3 out of 5 by from Great sound. Awesome idea. But no remote. I saw this demonstrated at Best Buy and bought it instantly. One was the Harman Kardon name and the other point was the Bluetooth. Unfortunately, when I got it home and hooked it up I discovered there was no remote. A remote would have been nice, especially when I'm lying in bed at night watching a movie on my PC. Sadly, because of this drawback, I returned it the next day.

Rated 5 out of 5 by from Oh. My. GOD. I bought this through a sprint promotion with my new HTC One M8 and I can NOT believe how amazing this thing sounds. I cant believe I own a speaker of this quality. I turn it up to 50% sound and I am blown away. If you want to hear it... go to a sprint store. Ask them to play it. TURN IT UP. It is incredible.
