OontZ Cylinder- Portable Bluetooth Speaker, 14 Watts, Deep Bass, Hi-Quality Sound, 100 Ft Wireless Range, IPX7 Waterproof, Shower, Home, Outdoor, Pool (Black)

I got one of these in 2018 and it’s still going strong. Great sound, stellar battery life, good connection. Durable, waterproof, I seriously can’t say enough nice things about this speaker. Granted it’s been seven years so something might have changed (hopefully it’s a USB-C power connection now), but seriously it’s a great unit that holds up well over time, great value for the money.

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.

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!

These speakers are quite impressive for the price. I purchased these to be used in a large room for a holiday party and they performed well. Filled the room with pretty good sound, clear with no distortion even turned up high. The battery life seems to be good. I ran them 6 straight hours with no isuues. They were super easy to connect to my Fire Tablet and to pair to each other. The bass is not bad but don't expect them to be as good as higher end wireless speakers like Bose. But for the price, they fit the bill.

• Exceptional and richer sound quality in its range. • Bass is incredible and lets you enjoy the entire low to mid to high range without damaging your experience. • Surprisingly clear at max volume. • It comes in basic packing for well protection along with a standard micro-USB cable and 3.5mm male-to-male cable. • When handled the feel is premium with solid and rubberized sides. • Controls are good with raised symbols that can be felt when lighting is low. • It dances its way around while on a hard surface at high volumes with high bass ;-) • Simple to pair. Speaker and microphone during phone calls are also of good quality • The battery easily lasts more than 20 hours when played under 50% of its peak volume  By IPX6 rating, it is nice to know that it is water resistant and it can be splashed on while by a pool or a beach or more likely water spill on it. I did not test it after getting addicted to its sound quality. o A battery level indicator would have been a nice addition o Sometimes the Bluetooth audio has continuous interruptions in playback when it resumes music playback after a phone call. Maybe a firmware upgrade can fix it.

Sounds great for size and price and is great that it has the aux input so I can DJ with it

No soy un audiofilo, asi que tomen con reserva mi comentario, pero el sonido me parece bastante claro y no aprecio ninguna distorsión. Creo que las frecuencias bajas son débiles, pero es entendible. Buena duración de la batería y simplicidad de los controles.

Great sound quality, no distortion even at max volume, very good fidelity and frequency response, full and reach sound, with enough bass, clear mids and highs. Battery life is great, no connectivity issues. Surprisingly loud for it's size, though it's more adequate for interior than for outdoor. It has a short delay between sound and image on video, but software update solves that. Nice design, sturdy enough for everyday use (mine has been fall from the table cause of vibrations from the bass and it still works). I own the first speaker for about a year and bought the second a month ago. Two of these paired in left-right mode is a very good job, they sounds a lot better, with even more clear sound, volume and true stereo separation. I think you can't get anything better for the money.

Ascolto molta musica ma non sono un esperto di casse/acustica. Questa cassa (la prima che ho acquistato del genere) è fantastica: il suono è ottimo, anche a volume alto, e la potenza è sorprendente. Ne ho acquistato una seconda per un familiare.
