    One of the best sounding bluetooth speakers

    Bass, volume, and fullness of sounds at higher volumes. Most bluetooth speakers automatically equalize the audio to have less and less bass as audio volume is tuned up in order to provide louder audio, less distortion, and generally a more pleasant experience. These speakers keep the bass and fullness going till almost at the top volume. Additionally, the bass extension is much deeper. This thing probably is clean and loud down to about 60hz or so, making most kick drums and bass really audible and not locking. Most bluetooth speakers roll off at moderate volumes well before 100hz-150hz or so. Audio isn't perfect, and there are a couple of holes in the frequency response in what sounds like the 100hz region, but a very pleasant audio experience. Note that this unit is somewhat large, and not easy to transport due to it's shape. Weighs quite a bit as well. When it is plugged into a power source to charge/play, audio output is MUCH better, as power to the 4 drivers inside is 15watts x 4 driver instead 7.5 watts x 4 drivers (as listed by HK). Negatives: The stereo pairing of two units for true stereo audio requires the HK Connect App, and requires a lot of fidgeting to work each time. It is not consistent and can be frustrating to use the app as it sometimes requires several power off/on cycles of the speaker to get it to recognize properly with the app (have found you'll know it's properly recognized when the power level of each speaker is displayed in the app). The Sony XB series is definitely much more intuitive here and can do it all with the buttons, making it more future-proof. When paired as a stereo pairs, where one unit is the left a speaker and one unit is the right, the audio and stereo separation are quite good. Couple other notes, there is a power adapter that charges and/or provides power while playing. It is a separate power brick and power cord that plugs into a standard 110v household outlet, and then plugs into the speaker via a barrel plug at 19v DC. There is also a 3.5mm line input jack and another jack and that I haven't used. The speaker grill/cloth material doesn't seem like it'd be the most durable. Audio occasionally stutters when changing or skipping tracks/songs manually, though if you pay a whole playlist it's hardly noticeable.

    I went to my local Best Buy a couple weeks ago looking for a clean sounding wireless speaker to use when I'm not in the mood to wear headphones. I listened to every speaker they had at my local store and wasn't really thrilled with any of the choices. Disappointed, I went back home and pulled up the Best Buy website to see if there were any other speakers offered online. That's when I found the Harman Kardon Onyx Studio 4, and it was even on sale for $150! The reviews here on Best Buy were very positive and I thought it was definitely worth a look. I raced back down to my local Best Buy wondering why I did not remember seeing that speaker only to find that none were out on display, although there was an entire pallet of them on the end of the aisle. I rolled the dice and took a chance buying the speaker without ever listening to it, hoping it was really as nice as the reviews stated. While in the checkout line, the Best Buy agent helping me started raving about what an amazing speaker I was about to buy and how everyone at that store LOVES that speaker! He wasn't kidding - this speaker is the best sounding wireless speaker I have ever listened to. I loved it so much that I went and bought a second one the next morning to pair them together in a stereo arrangement using the HK app. I can't even begin to express how much I love these speakers!! Great sound, beautiful contemporary look, super easy to use and a fantastic bargain when on sale.

    This speaker is powerful. We saw that it was on a great couldn't pass up deal, and after reading reviews and watching videos we decided to take a chance on this in Lieu of the Home Pod. Although it's not a smart speaker like the Home Pod (we were never interested in its "smart" ability.), we just wanted it for the sound. Well my goodness we were instantly blown away because this does the job, and we spent wayyyyyyy less than if we had pre-ordered Apples new "first" generation toy, not knowing anything about it. If you are looking for a portable speaker I suggest looking at this one. Once charged it holds charge for a long time. I have not timed it but I spent several days using it unplugged for hours and it's still going. However, you can keep it plugged in and it will play until your hearts content. Once again it's not a smart speaker so if thats what you are looking for, this isn't it but if you want a portable clear sound and deep bass, this is for you. If you can get it on SALE (like we did), get one or two for less than the price of one! but if not and you have the $450 it's worth a try.

    I purchased two of these speakers for Christmas Gift to myself. I paired both of these speakers together and cant believe the sound quality that came from these speakers! I own a pair of Old School Cerwin Vega"s with the BIG 15" woofer and two mid range, and a Super Tweeter. I get into trouble with these Cerwin Vega"s, so decided to get something smaller. I had these Harmon Kardon speakers only @ half volume and could not believe he Bass these speakers put out! AWESOME! I went upstairs to grab something, and when I came back down the song {All About The Bass} started to play, and it got so loud, I forgot that I had the Harmon Kardon speakers playing, thought that I had my Cerwin Vegs'a playing and tried to turn the volume don, until I realized that I was playing the Harmon Kardon speakers! I don't think though that the battery life is 8 hrs. I got about 4-5 hrs of music out of these. I have no problem with that though, because these speakers ROCK! If you can afford it, buy TWO of these and pair them for some OUTSTANDING sound..

    Amazingly Small for the Amount of Bass Produced

    Best portable blue tooth speaker that can punch out as much as 60 watts RMS. Much more volume, louder than those other more expensive competing blue tooth portable speakers. The low bass produced is amazingly body thumping and yet the mid and highs are clear and audible. Blue tooth 4.1 connectivity is fast and compatible with all my bluetooth equipment. No problem with synching. Works fine with connecting to your phone for hands free communication. If you play this speaker in your car or truck, the base resonates like a true active subwoofer. Keep power plugged in for even louder output. Able to connect 2 blue tooth devices and alternate between device to share audio output. You can also connect with traditional stereo audio plug, for audio devices that don't have blue tooth connectivity. Awesome speaker, you can pair it up to another onyx 4 speakers to extend the sound coverage. A speaker that you will not be disappointed with, for it's size, weight, connectivity, and overall performance.

    Outstanding Sound -- Very Portable

    I bought three of these on sale from BB. I gave one to my son for his birthday. We compared the HK speaker side-by-side with my Sonos Play 5 (gen 2), using both Bluetooth and a line-in to each speaker with a Dragonfly Red DAC. HK has more native bass and a slightly better sound for pop and jazz music. Sonos P5 has more clarity that is great for audiophile listening but wasted on normal music. Bluetooth connection (without DAC) sounds just as good for the HK speaker. Took the other two HK speakers to my company holiday party and used Bluetooth from my iPhone7 as the music source. Speakers would only work one at a time from my phone (need another HK component to link the speakers) but each speaker on its own blasted a large room (75'x75') with 50 people. Bluetooth connection is easy to make and speaker is very intuitive in operation. Do I prefer it to my Sonos P5? HK is way more portable (smaller/lighter) and has built-in BT. Sonos has more clarity for audiophile and hi-def music.

    Surprisingly Great Sound Quality

    This is easily one of the most well balanced battery powered bluetooth speakers on the market. Crisp highs and strong bass. This is the next best thing to having a high powered component system. It doesn't produce a room rumble like a home theater system would, but it still sounds great. I am using mine like computer speakers to sit in front of my laptop. It sounds much better than laptop speakers. It would also be great to take outdoors for background music at a party or pool where there might not be power. I especially like how they left the speaker magnet is exposed on the back like a bass port. When songs start pumping you can see the magnet bounce.

    We purchased the original Onyx speaker 3+ years ago and were impressed by the sound quality compared to other portable speakers. The original still works well ( except for the battery) and we decided to jump on the recent sale price for the most recent version. The size is about the same but the appearance is a little more subtle. The sound is rich, powerful and true, making listening of classical to rock music and everything in between very enjoyable. Turning on and off or disconnecting no longer has that annoying beep. There is a soft musical tone when it is turned on and I have not appreciated any noise when disconnecting my music source. I have not used it yet to talk on my phone. The intriguing bonus is being able to potentially connect it to other Onyxs ( new versions only) and enhance the listening treat. I just have to decide whether to get another. I recommend this without reservation. You will not be disappointed.
