    • Best option, great price, amazing sound quality.
Color: B074P79X9C
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! ... show more

    • Amazing speaker, it sells itself!
Color: B074P79X9C
I previously had a Studio 3 speaker, heard it playing in the Sprint store and was blown away, I had never heard a small bluetooth speaker so clear and full with a nice bit of bass to back it up. I had that speaker for about 6 years, had it playing at work all day long on top of my tool box in a shop environment, toted it home to use wherever I was working around the house. I estimated by the amount of hours it played at work every day during a normal work week, not counting all the time it played here at home, well over 10,000 hours of play time, before one of the woofers finally failed. The battery life was never impressive but it pretty much always stayed plugged in where I was using it, as it was directly stated it's more of a static speaker, it was never touted as a long play battery power bluetooth speaker. I know of almost a dozen people who have bought one after hearing mine at work and were blown away with the sound quality, and they all love theirs as well. So, naturally, when mine finally wore out, I replaced it with an Onyx 4. About the only thing different between the two, is the power up sound, and the passive radiator button color on the back. Otherwise they look identical. And my Onyx 4 sounds exactly like my Onyx 3. The added bonus is that with this new speaker, the battery life is good. There have been a few days I've set it on top of my box at 7AM and forgot to plug it in, and it was still playing when I went to put it back in my cabinet at the end of the day. For the price, this thing is amazing. I'm sure there are louder, harder hitting bass speakers out there, but not in this price range. ... show more

    • The best speaker for the money
Color: B074P79X9C
Everything about this speaker is just about perfect. It’s large and powerful enough to fill a decent-sized room with sound, yet small enough to bring in a backpack, the highs, lows, and midranges are all crystal clear, and the bass is honestly some of the clearest and most clean I’ve heard on a speaker. My only issue is its battery life is a little lacking, but I’ve been able to get a good 7 hours out of it wirelessly which is more than I really need, and is actually more than Harman/Kardon advertises I’m pretty sure so no real complaints there, plus you can just plug it in and leave it if you were you were going use it as a permanent speaker for your TV or something like that. I might even buy 3 more just to have around the house. The Bluetooth is great, it came a day early so no issues with the shipment whatsoever you can use Google Assistant, and Siri, and I’m fairly certain Bixby and Alexa work as well on it. Overall I’d definitely recommend it. 👍🏽 ... show more

    • Great! Can’t Go Wrong! Buy It!
Color: B074P79X9C
This thing is fantastic and the price is ridiculously reasonable. I’m a Bose fanatic. I have 4 pairs of high end Bose headphones, two portable Bose speakers, Bose home theatre system, and Bose stereo in my car. I appreciate crisp, clear audio with sufficient bass that does not distort with elevated volume. I started using Echo devices as a network for whole-home audio - which works great by the way, as long as your willing to put an echo device in every room right next to the larger speaker since they do have to be plugged in using an aux cable in order to sync the playback - but the Bose portable speaker we were using in our bedroom was never quite in sync with all the other speakers. There was a slight delay from it which I attribute to a hardware issue with the speaker. Bought this to replace it on a whim since it was so cheap (especially compared with the $400 Bose speaker it would be potentially be taking the place of). So glad I gave it a chance. It is not quite as crisp as the Bose speakers, but it has good depth with plenty of midrange and more than enough bass to fill a bedroom with as much sound as you can take with zero distortion. ALSO - there is no lag from aux and the Bluetooth connection is seemless. ... show more

    • Amazing Sound.
Color: B074P79X9C
Hello, I thought I would help anyone interested in a superb Bluetooth speaker. The Harmon Kardon Onyx is one of my fav. Speakers. This model is their 4th generation. The speaker has amazing full range sound being from low to mid to high. The speaker does retail for a lot and is well worth it. I use to have the second gen and just recently had to upgrade to the new model. The battery life is not too bad. About 9 hours of play back. You can leave it plugged in charging and use it at the same time. Also their is a HK App. Someone gave it terrible reviews, not sure what their prob is. The speaker does have the option to do stereo sound with another one or even do multi room audio with a bunch connected together. The app is where you can set it up those features. Also in the app has battery status in. You can also tell when your power button light starts blinking your speaker is low on juice. set up your speaker to use Siri with the hi app with the press of a button or just say hey Siri. Works fine too. You can’t go wrong with this speaker. For the price and quality and the sound. You will be amazed. Also one thing Harmon gets right is bass, it’s just right and works. ... show more
