    • A Beast in the Speaker Game.
Color: B074P79X9C Style: SKZZF137
There will never be another speaker better this one, absolutely hands down this original speaker will crush you heart if it ever to lose life. I know it a cousin to this speaker it just nothing like the original, if you can replace anything like the cords to save your speaker it’s worth it, I’ve had my a few years now. I’ve broken a leg and replace the cords but the speaker still jams like it brand new. ... show more

I carry this speaker everywhere. The sound quality is so amazing. Even if I’m not close to an outlet, I can play music with the battery in it.

    • Amazing speaker, it sells itself!
Color: B074P79X9C Style: SKZZF137
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

    • Great speakers for the price.
Color: B074P79X9C Style: SKZZF137
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. ... show more

    • The best speaker for the money
Color: B074P79X9C Style: SKZZF137
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

    • Very good speaker for the money it didn’t break the bank!
Color: B074P79X9C Style: SKZZF137
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 👍👍 ... show more
