Customer Ratings & Reviews

Compact,good,space saving,transportable speaker with great sound.

once the battery is getting low it turns off, the old model will lower the volume at that point. its not as loud as the old model the sinc has little glitches i don't think the batteries last long on this speakers, i don't use this speaker much and they don't hold the charge for a long time any more.

They told me it’s 8 hours of run time but it barely lasts me 4 hours. It was a waste of my money and honestly would like a refund or exchange but I don’t have the box anymore. Don’t promote something that’s not what it is

Sound of speakers is not loud at all. Will not recommend

Nice & cool speaker , but not the best or what we expect !

The jbl flip 3 is louder than this speaker. Was expecting a lot more but was disappointed.

Read the 5-star ratings which I concur with wholeheartedly. The app is very poor but does work. I do not know how HK can put out such a shoddy app. I Have a pair of OontZ 3XL Angle Ultras and they pair no problem, and they do not use an app. That said, the HKs are superior to ANY other BT speaker I have heard. They are lowering the price to compete which is a good thing for the consumer, but these are better than ANY BT speaker I have bought or listened to that cost under $300. There may be louder ones, but they do not sound as clear as the HKs. I bought a power bank that can output 12v, 13v, 15v, 19v. I use it to power the HK when I use it outdoors at family gatherings. The battery is older but still stores 20,000 mAh, with an effective output of 4,000 mAh when connected to the speaker. That gives me almost 5 hours of 75% volume without having it plugged into a wall outlet! When the power bank runs out of energy, the internal battery gives me another 3 hours of 75% volume (at a lesser wattage output but still plenty loud). The HKs use 19v input if you go the power bank route.

Bought this speaker for $170 on sale and I am blown away with the quality of the sound and the ease of set up. The sound, high, miss and lows are amazing, so clear, so brilliant, the bass is amazing. This speaker literally fills the room with the sound. Music and movies sound incredible, hard to believe it all comes from this one speaker. By far blows away it's competitors and I've tried numerous speakers.

My husband really wanted this speaker and I got got it or his birthday. I wasn’t really loud for the price I paid. We returned it and bought the jbs boom box.

The battery does not last for long time it say 3-4 hr but it will only work 1 and 1/2 hr or so ...

It’s terrible and made cheaply the sound wouldn’t stay on Bluetooth connection very poor

I was debating a long time to buy a new Bluetooth speaker. There has been such an expolsion of new Bluetooth speakers recently it will make your head spin. My brother had heard this speaker and recommended it so I bought it and wow is it impressive! Sounds so clear and loud without distortion I love It! Although its not that small to carry around as a portable speaker , I would gladly carry this thing anywhere. Great buy at Best Buy! Get it you won't be disappointed!

It's been 4 years since I've purchased this speaker. After 4 years of experience, I can tell you it's fabulous. You probably can't buy this generation so check whatever Harman offers as the last gen nowadays.

The speaker is the best I have used the sound is super heavy.

The most amazing speaker in the world. I'm not joking. You don't own this speaker you are depriving yourself of something AMAZING! 3 years ago we were at a car dealership and the music playing was AMAZING. I asked the salesman what stereo system they were using and he simply pointed to the floor. There sat the ONYX by H/K! The next day I bought one for $300.00. I would now pay $500 to $600 to own this amazing speaker! I don't know how H/K does it!

Speaker will not charge. Comes on for less than 30 seconds and shuts off

Is not good no good item I’m Buy I’m no recommend

3 years ago a group of my friends got together for what has turned into an annual event. At this gathering I was keenly aware of music coming from somewhere that sounded great and filled this large, high ceiling family room. Looking around I spied a speaker that turned out to be a Bluetooth Harmon Kardon. I've drooled over this speaker for 3 years until I was able to get it at a great price. This thing is just amazing. Crystal clear sound, great bass and good options such as being powered by battery or AC. Like the phone link. I know some people seem to think it's not portable enough, but if that's a complaint then they are either way too picky or don't appreciate the quality of this speaker. If you're looking for an awesome Bluetooth speaker, this is it!

This is a great speaker! Great sound, quality, and overall value!

Awesome speakers!!! Still doing a great job!! Thinking about adding more!
