Best portable speaker I have owned
Color: Black
This is the best quality portable speaker I have ever owned. And I've tried several. I bought two of these. One for me and one for someone else. We have had them for over two years now. Neither has ever failed. The sound isn't Bose but it is still pretty awesome considering it is only 14 watts. Must be due to the superior work inside the speaker. The sound really is very good. I have cranked this speaker up to its maximum volume and there was no distortion. The sound quality remained excellent. I also often use this speaker for watching movies on my laptop. Rarely are speakers, on a laptop, fantastic. So, this portable speaker allows me to have a more immersive experience while I'm streaming a show or movie on my laptop. The sound is amazing for this as well. The battery life is amazingly long. It really is 20 hours of continuous play! What I like about it is that if you stop playing your music, but forget to turn the speaker off, eventually it will turn itself off, which saves on the battery. Additionally, it charges back up pretty fast. It always quickly connects to whatever device I'm pairing it with. This includes my laptop or my phone. And its promise of a 100 foot range has been tested multiple times. This surprised me and I was glad to see that it delivered on this promise. It's triangular design makes it more stable and less likely to be knocked over (better center of gravity). It's weight is lighter than other portable speakers I've owned. To the point where it is light enough to carry, in one hand, while going on a long walk (if you want to take your music with you and listen to it). It really is that light. And, the triangular design makes it easier to carry around. The cover for its connections works very well to keep it waterproof. However, the cover is still easy to open which isn't always true for waterproof devices. Also, this cover is attached to the device. This means when you temporarily take it off to charge it (or connect with wires), you won't lose the cover. It says it can go under 3 feet of water. I haven't tested this out but do bring it into the shower daily. Its waterproof rating means that shower water running over it won't harm the speaker. I'm hoping, in the future, to have an opportunity to test it under water! If nothing else, I'd like to take it to the beach. That's another reason why this is an excellent speaker - you have to be really careful on taking any electronics to the beach, even if you don't plan on taking it into the water. Why? Normally, these things can ruin an electronic: the salty air, the sand, and any unintended splashes with salt water. However, this speaker would be perfect for the beach because it's built to withstand all of this! Another great feature about this speaker is you can connect multiple ones together to give yourself surround sound. Considering the incredibly reasonable price of these speakers, it makes it more reasonable (cost-wise) to do this. The controls, on the side, or easy to read and very easy to use. I highly recommend this speaker. It will last for a long time and will deliver everything it promises. ... show more

Great things come in surprisingly small packages!
Color: Black
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! ... show more

FANTASTIC sounding speaker with great volume and bass response.
Color: Black
I purchased this Angle 3 Ultra (Gen. 4) to replace an older Angle 3 Plus that served faithfully for 5 or 6 years - which I consider a pretty impressive workhorse lifespan. This Ultra is louder, features dedicated buttons (instead of having to press/hold to access stacked functions) , and upgrades to a modern USB-C port. It sounds fantastic, and the sound is huge for such a small footprint (approx. 6.5" x 2.75"). Not just in terms of volume, but the quality of the clean audio. There's no digital distortion/artifact stuff. Bass response is EXCELLENT; one could be forgiven for thinking it has an active subwoofer in addition to the 2 stereo speakers. It's balanced well. I use this both wired-in through the AUX for watching YouTube and movies on my laptop (basically as a soundbar to get increased/improved audio), and with Bluetooth for playing music from my phone. Both sound great. Bluetooth pairing is super easy. Probably goes without saying, when you're using the speaker to watch movies, just use the included cable and plug it in. There's ALWAYS a tiny time lag/latency when connected via ANY Bluetooth speaker. It's just milliseconds, but it's noticeable to the human eye, and you'll get the "lip-sync" effect. There are other solutions, but simply plugging in the speaker is the easiest way to circumvent the issue entirely. I looked at a couple different brands (Sony, Anker) in this price range, but I was really impressed with the previous Oontz model I had, so I went with this one. It's a GREAT little speaker. ... show more

Just as good as they were 5 years ago. Superior sound, stereo, and bass, but confused.

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. ... show more

GREAT sound for the shower, beautiful to look at, good battery life, super bluetooth connectivity
Color: SUP-Blue
REVIEW OF: OONTZ ANGLE 3 ULTRA SUP BLUE COLOR: If you buy ONE speaker for your shower, THIS IS THE ONE!. I listen to mostly rock and pop at max volume and I am a true audiophile. These will NOT disappoint you. I suggest you buy 2 for optimal enjoyment as this allows better stereo separation. PROS: 1) excellent battery life - more than 12 hours at MAX volume 2) superb sound given its tiny footprint. it is SMALL so the bass will not be palpable, but it is quite adequate in a small enclosed space such as a shower. 3) yes it IS waterproof enough to survive the shower. 4) AWESOME control buttons, all the functions separate as they should be. Not one button you have to press some magical tough to remember number of times for each task. 5) beauty in its design - love the blue one. 6) best bluetooth connectivity i have ever seen. it connects fast and STAYS connected. 7) easy pairing and you can control both speakers from the master one 8) superb value. CONS: 1) the bass is a bit lacking, but only if you REALLY like bass:) not even worth losing a half a star over. The sound is so good overall it more than compensates for this inherent shortcoming due to its tiny stature. You simply cannot get earthshaking bass without a large behemoth:) This speaker is a thing of beauty for both eyes and ears. Buy it you will love it. One CAUTION: If you stand this speaker up the long way, it will move around at max volume. Jump off shelves and stuff like that. Lay it down the LONG WAY on its rubber footed side so it stays in one place and will not fall down. SUGGESTIONS FOR IMPROVEMENT: 1) make this in more colors and designs - I'd like to see RED and PINK a design similar to the blue /light blue swirl, but with pink swirl on red and red swirl on pink. 2) add some cool LED lights that pulse and change color with the music beat. Comparison to the SONY SRSXB33: The Sony has a bit more bass feel to it, but bear in mind that the SONY is about 4 times the size and weight of the OONTZ and more than double the price. Unless you care about the gimmicky lights (yes they are cool) in the SONY, the OONTZ is far superior simply because of the song control buttons which are 3 separate buttons on the OONTZ, rather than one button and a song and dance about how many times to press it on the SONY. The OONTZ also pairs more reliably and easily to the bluetooth host than does the SONY. Overall max volume and music quality is almost identical on the 2 except the bass is fuller on the SONY due to its greater heft. Battery life is FAR SUPERIOR on the OONTZ - lasting at least 12 hours at MAX vs. 4 on the SONY. ... show more

Durable portable speaker with great sound
Color: Black
I’ve owned the OontZ Angle since the first generation, then upgraded to the second generation, and now the OontZ Angle 3 Ultra. Over the years, the improvements have been easy to notice. Pros ● Much better durability: My first- and second-generation speakers both developed charging port issues after about a year, but I’ve had the OontZ Angle 3 Ultra since 2020 with no charging problems at all. The build feels noticeably sturdier. ● Impressive sound for its size: It delivers clear vocals, balanced mids and highs, and enough bass to keep music enjoyable without sounding muddy. ● Compact and portable: It’s easy to carry, yet still produces a surprisingly full sound. ● Good value for money: You get a durable, portable Bluetooth speaker with reliable performance and sound that punches above its size. Mine has held up well for several years, which makes it a worthwhile investment. Cons ● Earlier generations had charging port issues after about a year. ● If you’re comparing it to newer, larger speakers, the compact size naturally limits how much bass and volume it can produce. Overall, if you’ve used earlier OontZ Angle models, the Angle 3 Ultra is a clear step up in build quality, reliability, and long-term value. ... show more

Solidly made with terrific performace for it's price range, plus it's splash proof with a option for stereo pairing.
Color: Black
I originally bought the original Oontz Angle 3 a year ago so I could play music in the shower or in the kitchen from my phone or tablet without worry. I wasn't expecting much from a (at the time) $30 blue tooth speaker but the sound quality was really nice for the price. Better yet, after a year it still performs like the day I first got it even after a few drops. So when I saw that Cambridge came out with the Oontz Angle 3 ULTRA and that it was going on sale for the same price as the original Angle 3, I just had to get one. There been some significant improvements over the original Angle 3. - Better design, closer resembling the Oontz Angle 3 XL. - Added track selection buttons on the speakers. - Splash proof. While I don't necessarily feel it any better than the original's, it always nice knowing I can put these in a bathroom or kitchen without having to freak out if they happen to get a little wet. - Better base. While the original Angle 3 had good sound quality and decent base, the ULTRA pumps up the base to the next level, all the while never at the cost of becoming distorted at max volumes. The ULTRA lives up to the "Oontz" brand name as it can actually produce base you can FEEL. I have a set in my bedroom about 3 feet from the foot of my bed and I can feel every beat in my foot board easily. Surprised the hell out of me the first time, I'm a little amazed how much they improved the base in a unit that's only slightly bigger than the original. - Speaker Pairing. A main reason I gave the ULTRA a shot was due to the fact it has the option to pair with another ULTRA speaker, something that was only available from the $80-$130 Angel 3 XL. While I had a little trouble initially pairing two ULTRAs together, they were never a problem once they were. You're given the option of having a dedicated Left and Right speaker for a stereo set up or you can do a duel stereo on each speaker which is ideal if you moving back and forth between two rooms and want to enjoy music or an audio book uninterrupted. - Better Bluetooth range. On the original Angle 3, if I were to leave my phone or tablet in my bedroom and then move my speaker to the kitchen which was about 40ft away through two thick walls the speaker would start to lose connection and break up. Not a problem for the ULTRA, and the same goes for paring between two speakers. I can now leave a speaker in my bed room and bring one into the kitchen and have no problem playing audio on both no matter what room my device is in. That all said, there still could be some improvements. When paired, turning off the main speaker (the "left" speaker) will turn both off, but turning it back on won't turn them both back on. That's is a significant oversight in my book. Also I occasionally have issue with my devices recognizing the speakers, especially if I have more than one device paired to them and I want to switch between them, but that might have more to do with my devices than the speakers themselves. Worse comes to worse, you'll have to repair but it doesn't happen very often. Finally and this is more of a tongue in cheek criticism but they kind of make the original Angle 3 obsolete. As I write this the Ultra is $33 and the original is $25. At those price ranges, the $7 you save by getting an original Angle 3 just isn't worth it because the ULTRA provides so much for only several dollars more. Honestly, If the ULTRA is going to be $30-$33 depending on sales, I wouldn't pay more than $15 for the original Angle 3 and considering how often they go on sale I sure you'll see one for about $20, but that still seems high... Then we have the other end of the spectrum. Up to now I was really debating on getting a $130 Oontz Angle XL, mainly for the increase performance and pairing feature. And while knowing it often goes on sale for around $75, I still probably won't get one now that there's the ULTRA at less than half the price. Granted, I'm sure the XL even crazier in performance, loudness, etc.. but the ULTRA does such a good job as is that unless I start hosting huge outdoor parties regularly, I don't have have a need or desire for it anymore. Two ULTRAs do a hell of a job already providing loud high audio quality music in any of my home's rooms so unless the XL starts going on sale in the $60 range, I'm good. But who knows, that might happen when Cambridge comes out with a Angle 3 XXL or XL ULTRA or roll out with an Angle 4 line of speakers. Overall the Oontz Angle 3 is a solid choice for a Bluetooth speaker. It's built well, sounds terrific, will hold up to test of time, can be paired and is water resistant, all at a fair price (if bought for it often sale price of $30). ... show more

IMO worth the buy, so I bought again

Bought one of these years ago (2017) and misplaced it in a move a few years back, so I bought another one. Basic black appearance...I considered the blue one, but I plan to use it on my desk with my computer when I'm not using a bluetooth headset for sound, so the black matches my decor. Fits nicely underneath my monitors without blocking my view or getting in the way of anything. Buttons are large and really easy to press and use. I haven't charged the new one yet to be able to say how long the battery life lasts, or how well it sounds, but I know with my old one it was a pretty long time before I had to recharge, and the sound was better than I'd expected. All around great product, IMO, and the price is ideal. ... show more
