Customer Ratings & Reviews

There are three of these speakers existing in my family at this point. Everyone raves about the clear highs and mid sounds you get along side of booming base. We use it in every room throughout the day. Not to mention the ability to answer phone calls and use it as your speaker phone.

This speaker is perfect for the audiophile in the family. Great sound and great battery life!

Fantastic sound quality and very easy to setup. Love it.

I purchased this speaker and was immediately impressed by the quality, and awesome sound. It was a lot more than I expected. It is easy to operate and very convenient. It is perfect for indoor or outdoor use. I am very pleased with this speaker and I highly recommend it to anyone.

this is the 3rd one I have bought. One for my wife, my son, and now myself. Awesome sound !

I love my speaker. It has the best sound quality than any of the other speakers I’ve used.

This speaker is a work of art I had to buy two and they sound amazing welll designed the sound is out of this world. Excellent buy and would recommend to everyone. If you are looking for speakers . Look at these first and they speak for them selfs they are in my apinion the best .

Okay the clarity of this thing easily rivals Bose. In fact way surpasses Bose dollar for dollar. At 1/3 volume the bass is felt in my stomach and the melody is making my brain tingle. More than enough power to flood my 20'x15' bedroom with super-quality sound. What a treat.

I bought 2 of these to pair them and use it for my daughter's birthday party. The room is about 800sqft and it filled the room nicely. The bass is awesome even if you increase the volume full blast. I use it now for my living room with Echo dot connected to it and play my music.

This is the second one I bought, as the sound is impeccable at any volume I play it at.

This is the second Harmon Kardon speaker I have purchased. Sound quality is very good.

Onyx 3. Very good sound for the size and price. I bought two speakers so that they could be paired together for television use. Connecting one speaker to the tv audio out via cable and everything is fine. However, I was disappointed that after pairing the speakers, there becomes a noticeable delay (guessing 3 seconds) of the audio output of the speakers with synchronization of the tv picture. I purchased the Onyx 3 model since the Onyx 2 did not allow two speaker pairing.

For those who enjoy quality sound via Bluetooth, this speaker is for you. It has dynanmic range,clear sound with a nice bass-kick. The price point is very good with a name and reputation that stands behind their products. You will not be disappointed, what are you waiting for?

Got a great deal on this for my son on Black Friday. He asked for the Bose Soundlink, but when I compared the sound with this speaker at the Best Buy store, the Harmon Kardon had way better sound, especially if you want to be able to hear the bass. Great speaker for its size.

Sounds great. Got it on sale at $159. Good speaker for the price and easy to set up.

None of the good quality bluetooth speakers are inexpensive, so I thought I would like one from a company with a good reputation. What really sold me on the product was the ability to network another Harman bluetooth speaker to this one for multi room audio. That's the feature that sold me on it, as I can connect this to another Onyx 3 speaker in another room, and I keep this one in my office on my desk to hear the music, and for handsfree phone calls. So far, it works great.

I use with my echo dot and the sound is great. I bought 2 and pair them together.

Got this when the price was very cheap, and amazing product. Highly recommended.
