Customer Ratings & Reviews

These sound just as good as the ones before but with updated battery life and the link system you can connect multiple speakers to one blue tooth source !

This product performs far beyond expectations. Easy to set up and hold the battery charge quite well. The sound is simply superior as it hits all the highs & lows & the Bass is great & the sound is crystal clear. Makes one feel like their in a movie theater when audio hooked to television. This speaker is truly worth every bit of the money.

Very nice sound, thick and rich!! Not very heavy but I like it because it feels like it is not cheap! Battery life is very good for what it puts out!

What a good speaker! For the price $145 dollars, it is a great deal. I use to buy Bose speakers but I decided to give Harman a chance. I have tried other HK speakers and amplifiers and I know this is a good company with good quality products. My personal opinion, this is a great deal and your best option. Before buy the HK, I got a Amazon Echo plus and the sound quality was really disappointing. So, I had two options: bose revolve or HK Onyx 4. I considered JBL Pulse, MegaBoom, and others but comparing price and functionality I found that HK is the best option. Some people complaint because it is too big and maybe for them it is not portable, but Im not looking for a speaker to go out, I was looking for the best sound at the best price. Additionally, I got portability. This new model has a 8 hour battery, the size is not too big but it is not small like a sonos or other speakers. I found that this model has a multi speaker option, so you can connect up to 4 speakers at the same time. In conclusion, this is a very very good bluetooth speaker, with a good battery (8 hours, enough for a party), quick connect option and multi speaker option. Very complete device!

Purchased this on sale during Xmas for my son, it was very reasonably priced at ~60-70% off. At that price point, it would be very difficult to find anything comparable as it produces very good sound quality (both clarity and bass) for a portable speaker. It is also convenient for him to take along, whether in his car or to go somewhere to hang out with friends.

Fantastic balance of highs and lows. Connects flawlessly, performs perfectly. I'm going to purchase a second unit to add R + L stereo to the mix.

I got this speaker for the quality and sound of Harman/Kardon doesn’t disappoint,I now use it for my tv and listening to music through Bluetooth.

Best for the price! Sound quality is amazing! Had friends over and they couldn't believe all that sound was coming from the one portable speaker!

for the price this is a no- brainier ! great sound at an amazing price. blue tooth connections means my laptop and IPHONE both can play my music.

This speaker is better than my Bose Mini and cheaper. I can't believe the sound quality, battery life, and you can talk on the phone through it.

I originally thought it was going to be a big speaker with the box size but it's pretty compact and the sound quality is amazing. So worth it!

Best Bluetooth speaker ever! Great frequency response and tremendous volume for its size. Dream Bluetooth for any audiophile. Handsome unit.

Absolutely love my Harmon . I had the 3 but the speaker blew out, but I had Geek Squad protection plan and was able to get the Vaule i paid for my old one toward my new one! & bought the protection plan again ! Speaker looks nicer & also sounds amazin ! Perfect for parties!

Sound is very impressive for size of speaker, very good battery life. And during Black Friday sale for 150$ its the best thing on the market

This Harman Onyx Bluetooth Speaker packs a powerful sound! I can hear my music from every room without having to move my speaker from room to room. Its the perfect size for a desk or to place directly on the floor. Paring it to my cellular device was extremely easy. Although I purchased it on sale ( even when it’s not on sale) it is worth every penny

This speaker it’s an excellent speaker that I ever have, So pure and clear sound with great bass. This speaker it will not let you down.

I did look at the online reviews before buying. Got a great discount too! Really good sound and great bass. Good for outdoor use too!

I’ve owned an HK speaker before, not an Onxy, so when that one gave out on my after some years I decided it was time for a new one. This speaker does not disappoint it is just loud enough for me, lightweight, and easy to move around. I plan to purchase at least one or two more to use the party feature.

I had never heard of this brand, so I was skeptical. However, this small speaker packs a lotta punch! I am/was happily surprised.

Great speaker with great sound and the bass is amazing, definitely don't need the volume up high if you live in a townhouse or small space. The battery is a bit of a minus but the sound quality out ways that con. It's pretty light weight and easy to carry. There is one other minus with not being able to see the power button when it signals its dying, since there's no sound to signal it needs charged. Overall I bought this when it went on sale for $99.99, so its definitely been money well spent and haven't had any major issues.
