OontZ Ultra Bluetooth Speaker 5.4 | IPX7 Waterproof, 14W Enhanced Sound, 20-Hr Battery, 100ft Range, Deep Bass & Clear Audio, Durable Speaker for Pool, Beach, and Shower (Black)

Was looking for a speaker to pair with my recent laptop purchase that only puts out low-volume via its' own speakers, and this fits the bill.Considered a number of other options, but didn't like the lights, nor no-name aspect of the ones under $20, even with the good reviews. Chose the OontZ Ultra since I liked the original OontZ Angle purchased years ago. This is a solid build, great design, and puts out a nice blend of frequencies in non-distorted sound.When I got it, it was semi-charged, and was fully charged within an hour, even though I was playing songs from my laptop. Very satisfying bass when within 5-10 feet. Crisp high-frequency production, and very good mid-range sounds. Listened to a number of 1970s songs over 2 hours and was very happy of the sound quality.No need to crank up the volume control to 100%, the sound for 1970's rock was perfect at about 67-70% for my setup.I chose this over the Angle3 in part due the usb-c charger connection. Price was maybe $5 more, and I think the bass is a bit fuller. I do think the Angle3 is a great option, as it does put out bright mid-range sound. Bluetooth connection was flawless and quick. As with the original Angle, OontZ/Cambridge Soundworks puts out a very high-quality and solid build.At the Prime-Day sale price, this was great value for money!

I love these speakers so much, I currently have 3 and will be buying a 4th when they go on sale again. Great quality sound, durable, easy to carry around, lightweight, Bluetooth set up is super easy for just one speaker. The first time I tried to connect them (surround sound) it was weird but now it's easy. Battery life is incredible. I'm going to buy a few as gifts soon!

My luck with wireless Bluetooth speakers has been hit-or-miss over the years ... but mostly miss. Even some of the more expensive ones I've tried have been woeful. I can live with a shorter battery life if I have to, but I do not want to sacrifice sound quality. And unfortunately, in my experience, most speakers fall short in that respect. HOWEVER, the OontZ Ultra is (for me) the best of all possible worlds and is surprisingly amazing!I was a little wary about ordering these, because I wasn't particularly familiar with the OontZ brand. However, after doing some online research and reading the reviews, I realized that I've apparently living under a rock.What first attracted me was the price. Speakers run the gamut in terms of cost, and while I wanted a solid set of portable speakers for my master bathroom, I didn't want to spend a fortune. The fact that these were an affordable mid-range option put them right in my sweet spot.The sound quality is shockingly good! I'm not an audio geek, so I can't speak to all the technical specs, but I DO know good sound when I hear it. I want crisp, clear treble and a deep, resonant base, without any tinniness or muffling. And these tick all those boxes in spades! Particularly compared to cheap little Bluetooth radio I'd been using, this is a whole new world of sound.The water resistance was another huge plus for me, since I wanted to use these in the bathroom when I was getting ready in the morning. I haven't tried to immerse them in the water or anything, but I do keep it perched on one of the shelves in the shower, so it's being regularly splashed. After a couple of months of daily use in the shower, it's still going strong.The battery life far exceeds anything I'd have expected. I probably should have measured how many hours I get on a single charge, but I generally only have to charge it about once a week. I'd guesttimate that I average at least 10-12 hours of playtime on a single charge? And when I do need to recharge it, it charges fairly quickly.I loved it so much, I bought a second one to pair with it, for a FULL stereo effect! This was the first time I'd ever paired multiple Bluetooth speakers, so it took me a few minutes to figure out the process (it would have taken less time if I'd have read the directions), but it was well worth the effort. After the initial pairing, when both speakers are turned on, they automatically re-pair on their own, which is incredibly handy.I LOVE my OontZ Ultra speakers!

I bought a 2 of these speakers 5 years ago, and they are still working as well as the day I bought them. Most recently, I had to replace a different brand of speakers that pooped out. I shopped through the various brands, but kept coming back to these. I bought 2 of them for stereo sound, and I love them. I use the new set in my bathroom, and the older set is being used as the replacements in my basement work area. Since I had kept the older set plugged in, I was concerned this would wear out the battery, but the batteries on both speakers still hold a charge and connect automatically when I turn them on.My husband also has a set of these speakers that I bought him for Christmas 5 years ago that he uses on an enclosed back porch that is his workshop. Both of us have these speakers connected to Amazon Alexa devices to listen to radio and a couple of music apps. When connected to the Amazon Alexa devices, I turn the volume on the speakers to maximum so the volume can be controlled by the Amazon Alexa device.So, why do I love these speakers?1) The cost for 2 doesn't break the bank.2) The stereo sound is superior. When using 2 speakers in stereo, the sound seems to come between them. For input that is stereo, you get a great separation of sound.3) Once you connect the left speaker as the main speaker, and pair two speakers, they connect automatically when you turn them on. Connecting two speakers in stereo mode is very easy, and they reconnect even if you turn the off.4) Whether kept plugged into power or not, the speakers work equally well. I kept one set plugged into electricity all the time and the other was plugged in only when it needed to be charged. Both work equally well.5) When using 2 speakers, both are controlled by the first speaker connected. If you increase volume of the initial speaker, it also controls the volume of the second speaker. If you shut off the first speaker, it automatically shuts off the second speaker.6) Sound quality, bass, and stereo separation is superb in my opinion.I really do love these speakers, especially if you get two for stereo sound, and would highly recommend them. These speakers are not expensive, and, in my opinion, beat the sound quality of more expensive speakers. In addition, the life span of these speakers makes them more than worth the cost.Update 3/20/23:The speakers pictured and described were bought for me by my husband November, 2021 that I installed in my bathroom, and moved a set I bought April 24, 2018 to my basement work area. I had also bought a set for my husband for Christmas December 11, 2017. All of these were the same and used the same micro USB cable for charging.December 5, 2022, I bought another set just to have an extra set in case I needed it. In March of 2023, I discovered that one of the speakers I bought in 2018 was no longer charging. So, I bought one more of these speakers to replace the one that was failing. This speaker had the same mini USB charging cable, but would not pair with the older speaker that was still working. When I took out the speakers I bought 12/5/22, I discovered the charging cable on both of these was USB-C and neither of them would pair with the older speaker or the one I just bought in March of 2023.I finally did pair the two speakers that had the USB-C charging cables after a lot of frustration and aggravation. I found that every one of the orders is linked to the same sales page on Amazon. The newest speaker I bought uses the same charging cable as the older speakers, and the set I bought just previously to this on uses USB-C.This makes me wonder exactly what you are getting when placing an order on this page. Judging from my experience, I wonder if you get an older version when you buy only one speaker. They all look the same, so how could you possibly know. At any rate, the single speaker I bought would not pair with the older speaker having the mini USB power cord nor would it pair with either of the speakers that had the USB-C power cords. I am returning the most recently purchased speaker since it won't pair with any of the other speakers I have.I hope this review was helpful for you.
