Harman Kardon Onyx Studio 4 Portable Bluetooth Speaker - Black (HKOS4BLKAM)

Absolutely stunning design and sound!

After researching the top blue tooth speakers, I decided to purchase the Onyx4. It suits my needs perfect. Super elegant, easy to set up and absolutely stunning sound. I adjusted my Eq on my phone to my preference and it sounds velvety smooth, deep bass, crisp highs. Does not distort at full volume. I don't need anything that is waterproof or to turn on my lights. This is to me, the next best thing to a 2 channel audiophile system, but for just a couple hundred bucks. These sell for less, but there seems to be a catch, such as "other new" or refurbished. You will not regret this purchase, unless of course you like to swim or kick dust on your fine audio equipment. Read full review

Superior sound quality and design

I have an HK Onyx Studio 2 and absolutely love it. I wanted to add another to the house. The sound quality is superb and amazes people. It is surprisingly loud with crisp highs and very good tight bass response. It is also a great looking design. I love that I can connect my old unit and new unit and play them in unison and add more if I want to. I am an HK fan and was skeptical when I initially saw this portable speaker. It truly lives up to the HK reputation and am happy to add this to my HK family of products.Read full review

Good buy.

More bass needed, but place it against a wall, or buy the next model. It's great for me, sound, portability and the great Style, simple but demanding your attention.

Great sound, so much bass.. So nice to listen music

I like to listen my music with bass, that ectra kick is what i love but in order to enjoy that you need big bulky equipment.. But this speaker gives you just that in a small speaker. Very loud, crystal clear mids and the bass awesome. Very impressed with the sound it produces, i was hesitant because of the price $129 but now that i have it is worth it no doubt. I listen my music and i enjoy it, so rich and crispy the living room gets filled with sound and you dont feel is struggling to produce it. So impressed with my Onyx the best i ever heard for its size. It will beat any other speaker even much bigger ones with is capcity to produce nice sound and the bass.. Just waow

Harman Kardon ROCKS!

This HK Bluetooth Speaker is one I have been watching for 3 years after seeing it in a local Sprint store. Price was $350 and now around $125. Love the punch this delivers. I feel it sounds better than the Bose series due to the way it delivers a little bit nicer mid range to compliment the crisp highs and deep lows. Price, Value, and Quality is spot on. I would compare the sound quality closer to the Klipsch Pro media 2.1 system. My reason for using HK over Klipsch is the Pro media 2.1 Sub Amp continues to fail every 2 years and I'm tired of it's constant repair costs. Also love that the HK is portable for all events and can be paired with another. HK Onyx 4 on up are all great speakers, the 4 is just my preference in design. Either way this jewel will fill a room with awesome sound quality.Read full review

Not great at retail price.

In it's $450+ retail price range, this speaker in good, but not a stand out.
Considering you can pick these up for 80-100 dollars, they are by far the best thing out there.
Strong bass & mid-range... Adequate high end, Good battery life and solid bluetooth functionality make these speakers a bargain.
Tip, the passive radiator at the rear of the speaker greatly enhances bass if you place the unit in front of a wall or cabinet, or in a corner.Read full review

Excellent speaker for home and backyard use

Not quite durable enough to be the go everywhere speaker, but for home and backyard type use this speaker is phenomenal. The rich sound, loudness and ease of use of this speaker make it a definite top pickRead full review

This Onyx is more than semi-precious

Another quality product from this iconic brand.
The sound that emanates from this speaker is nothing short of superb.
Unit is easy to set up and use, and battery life is above average.
I bought another shortly thereafter as the 2 can be paired together.Read full review

Best Bluetooth speaker you will ever own

The speaker is absolutely amazing. I have owned several Bluetooth speakers that were both portable and in home. This one is both. I can't gauge how well it would work in a Room with high ceilings but in my standard 8' ceiling house it's absolutely perfect. A friend of mine has a Bose Bluetooth speaker that costs 3 times as much and it is close but still nowhere near as crisp and clear as the speaker. If you can pick this up for around a $100 or so it is more than worth it. It sounds as good as an entire stereo system and if you want to you can pair up to a 100 of these speakers together and give you the most incredible sound quality you will ever have in your home. Now I can't attest to the longevity of the battery because I've only been listening to it for about an hour but I find it hard to believe that Harman kardon with as much prestige behind their name would invent something that doesn't live up to its claim. As I mentioned earlier it is way cheaper then a Bose speaker and always will be because Bose never puts any of their speakers on sale ever. If you don't have the speaker already you need to go buy one you will not be sorry wherever you live it comes with an adapter to fit your specific region of the worldRead full review

Good brand speaker

I owned the second generation which was a great speaker. The 4th generation has more functions and gives out crystal clear sounds. I'm loving it.
