Customer Ratings & Reviews

Bought 2. Great for parties. Light and portable. Excellent sound. Batteries last a long time. Speakers not good for phone use.

The speaker sounds amazing. Build quality is excellent. Ive had it for over a year and had no problems with it. Sometimes I have it to max volume for hours at a time and it don't distort or cut out. Connects to my phone just by turning it on. I would recommend this speaker.

This speaker is amazing especially since it was 65% off for the holiday specials. Whole house sound in such a small package.

This speaker is everything it says it is. I use this on my back deck and or in my house and surrounding areas. The sound is amazing it connect with your device without any problem. Pick your tunes and play. It does so much more as well. Did I mention the weight is light weight. A plus in my book.

Purchased this Harmon Kardon speaker from Best Buy on sale, outstanding sound, amazing discounted price for such a high quality brand and speaker. Play my TV, music, and Bluetooth through it everyday and it just sounds so crisp with enough bass to fill the room but not overwhelming. Very happy with my purchase.

Loud clear quality sound. Very compact. Easy to use

I love my speakers. I purchased two speakers and the sound quality is terrific. The bass is so powerful. I have to sit them somewhere with plenty of room, so they do not fall, from the strong vibration. The battery does not last as long, as stated in the owners manual. I usually keep them plugged up after 3 hours of use.

This blu tooth speaker has a assume sound. I really enjoy it everyone really enjoy listening to music with this speaker.

Bought it Christmas of 2018 and using it almost daily at home and at work. I love the sound quality specially the bass. Battery life is above average, and connectivity is good. It is quite bulky compared to other brands but well compensated with its sound superiority.

This speaker really sounds great. It is a little larger than many others but the bass clarity is worth the extra size.

We love our new speaker! It sounds great and looks super stylish with our decor!! I would recommend this to everyone!!

At first, I bought one just to see how it sounded. It sounded so good I bought a second one to pair in Stereo Mode. It's amazing. Reminds me of the times I was a child at my great aunt's house who had a whole stereo system set up in her living room. With these, you get that same amount of sound without all the bulky equipment. The sound is crystal clear with the treble and the bass is deep and rich. The only flaw is the Harman Kardon App. Which has nothing to do with the speaker's performance. The app is slow to load and it does not keep your speakers in stereo mode. Other than that, great speaker at a great value! You will not be disappointed.

This speaker is one of the best on the market for quality sound. I have bought several for friends and have 3 myself.

Awasome speaker love the bass and the way it looks from the back You could seetheair thumping the speaker in the rear

Excellent bass and sound quality. I was confused between Onyx Studio 4 and Onyx studio 5 but decided to go with this one as the balance between treble and bass was better in this one as compared to 5. Happy with my purchase, will totally recommend it.

This speaker has amazing sound with built in bass. I got it while on sale for $149.99 and would not pay more than $199.99. I brought three within a two week time frame: two for XMAS presents. Love it!!!

The sound is loud and clear And it’s easy to connect on the phone and it’s good for parties but the best is the sound

This speaker sounds great! It has far exceeded my expectations. Because it is portable, I can move easily around the house. It sounds better than my Sony Soundbar HT-CT390. Bluetooth signal remains connected... when listening to music from the computer in the basement and speaker is upstairs.... easy to setup...

Unbelievable sound!!! Fills the room with punchy bass and clear highs! Harmon Kardon hit it out of the park with this one! Fantastic Bluetooth speaker. You have to have at least one in your home! Great for outdoor use too. Sound carries well!

I’m so glad I grabbed this when it was on sale. I’m just mad that I did not get another one for a gift. Great sound
