Onyx Studio 4 Wireless Bluetooth Speaker Black (New Model, 100

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.

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!

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. 👍🏽

I went on a trip aboard a small cruise ship last year and they had the Onyx 3 onboard for us to use... was impressed with it then whether on the ship or on any of the small islands we visited. Again, recently I stayed in a nice hotel in Singapore whose suites had the Onyx 3 in them, and that did it for me. It just sounded so good. So I bought the successor, the Onyx 4. Though I had some minor concerns about this being a knock-off, given the good price, it sure seems to be the genuine article in every way, from packaging to documentation to (most importantly) performance. Sounds terrific, syncs up effortlessly, and even came with several different plugs to use, which is great for me since I live overseas. The adapter itself is universal voltage, which I knew, but didn't expect the bonus of four different plugs being included, which precludes the need to use a plug adapter. The plugs included were North American, European 2-pin, UK 3-pin, and Australian angled 2-pin. I've been very pleased with the sound quality and battery life. With two woofers and two tweeters, plus good porting, the Onyx 4 delivers nice bass and excellent room-filling sound overall, in a portable unit (weighs about 2kg/4.5 lbs). There are so many Bluetooth speakers out there, it's hard to know which is the 'best', but the HK Onyx 4 sure does a fine job for my needs.

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.

Over the years, I have had multiple Bluetooth (and non-Bluetooth) portable speakers foisted on me for various reasons, so while I'm not exactly an audiophile, I have a fairly decent range of experience with these things for the average person. This is definitely one of the better ones ESPECIALLY at this price point. If you're willing to drop whatever cash you need to to have the best sound possible, you can certainly get better. But for the cost of a sit-down restaurant meal for one person? Not likely. Sound quality is GOOD but not GREAT. Sound carries really well. Sitting in my living room, I can hear it clearly even at low volume from the bedroom. In my office at work, I can hear it from down the hall. The specs say it can stay connected to its Bluetooth source for 33 feet, but I had it connected at nearly 50, and it was still working (although it started to get spotty before I realized my phone was in my pocket). When I used it at a tabletop game store, it drowned out everybody else's speakers even at low volume. Battery life seems to be about 4 hours at low volume before it starts complaining. It charges fairly quickly. It FEELS very cheap when you hold it, so I'm not sure how much of a beating it can take. Not that it's expensive enough that you have to buy it a carrying case (the case would likely cost more than the item), but you should probably be gentle with it. I have not tested its supposed waterproof capabilities (and don't intend to, because why on earth would I?). Assuming it doesn't break in the near future, I'd be willing to buy this again, and would be comfortable recommending it to others as a good casual speaker.

My girlfriends brother bought this same speaker a couple years ago and when i first heard it by the fire i was blown away. I've heard all the beats pills and plenty of Sony wireless charging bluetooth speakers but this one takes the cake in terms of “clarity” from what Ive heard. It's not going to boom a room down with bass but the sound is so balanced it needs nothing else. I listen to a very wide range of music and it does amazing with all of it. If you want to bump bass and only listen to clubby party stuff i don't really recommend it simply because i think there are speakers better designed for bassy shit but have less quality And you can get those possibly cheaper. I do think though if you want an amazing balanced sound / Crisp and clear audio this is your speaker. I listened to some Mars Volta to break it in and it says a lot to me if i can hear their layers through a bluetooth speaker. Sounds better than my jbl’s in my car. And its only $150 that is mind boggling to me. Enjoy your sound 🎉

This is my third Onyx studio 4 Bluetooth speaker I own. Well in my opinion I think the sound is fantastic with three of them going it actually sounds like I have a subwoofer in the room. Now the thing I really don’t care for on this speaker is the bluetooth I think it is at 4.2 Bluetooth and with that they keep dropping out on one another and that is so annoying. So I’ve reset all the speakers more times than I can count along with my devices I have connected to them, and it still didn’t help. So now I have them hard wired now and I don’t have to worry about the Bluetooth kicking out on me anymore. One other small complaint I have is I wish you could play them plugged in all the time when your using them, because when they are in Bluetooth mode they lose around 20 watts each and that is quite a bit of power to lose. Other then my two complaints I have no other problems so all in all I give them a two thumbs up 👍👍

Ho istallato due nella camera e uno nel bagno e ci metterò un terzo nella seconda camera. Il pairing col'iphone funziona perfettamente. Bisogna collegare solo uno al telefono, l-altro si collega tramite un tasto sul speaker al altro speaker. Facile. Il suono é davvero impressionante, un pò bass heavy. Comunque ottimo acquisto.

The speaker has an amazing sound quality. Connectivity to Bluetooth is great.

Quando você recebe o produto já fica impressionado com o design. Depois você liga e se apaixona. Moro em um apartamento de 60m2, mantenho-o na sala e escuto música perfeitamente em todos os cômodos. Ótima qualidade de som, graves e agudos. Bateria dura bastante, o que me ajuda a movimentá-lo quando quero sem me preocupar em levar o cabo ou estar perto de alguma tomada. Comparado com outros aparelhos é caro, mas digo que se você tem o dinheiro para comprar, vale à pena. Já tenho há alguns meses, qualidade de som e bateria permanecem os mesmos.

I love the shape and speakers performance

Für draußen und laute Partys eher nicht geeignet. Wenn man jedoch auf der Suche nach einem edel verarbeiteten und wirklich gut klingenden Lautsprecher für die Wohnung ist, in fast jedem Fall die richtige Wahl.Wenn man den Speaker frei aufstellen kann und der Raum nicht zu klein ist, wird man mit ausgesprochen erwachsenem Sound belohnt.
