OontZ Angle 3 Ultra Bluetooth speaker , $49.99

Sound Advice Speakers review By Don Lindich

Manufacturer website: theoontz.com

The OontZ Angle 3 Ultra ($49.95) replaces the OontZ Angle 3 Plus in the OontZ line of Bluetooth speakers. It is the mid-sized model, with the OontZ Angle 3 ($24.95) below it and the OontZ Angle 3XL and OontZ Angle 3XL Ultra models ($119.99) above it. (Please note if you want a bigger speaker, I recommend you wait for the Angle 3XL Ultra as it is much better than the Angle 3XL.)

OontZ has been the best-selling Bluetooth speaker line on Amazon for years, and the new Ultra models are touted to raise the bar dramatically for OontZ sound quality.  Given the affordable prices, I was anxious to find out for myself if it was true or just a marketing pitch.

Two front-facing drivers provide stereo sound. A passive bass radiator on the back of the speaker enhances bass response, making the speaker sound much bigger than it really is.

The OontZ Angle 3 Ultra is IPX6-rated water resistant and can play up to 20 hours at 2/3 volume with a fully charged battery.  The OontZ Angle 3 Ultra  comes packaged in a plain black and white box with a MicroUSB USB cable, miniplug cable and well-written, directions that are easy to understand. As most Bluetooth speakers do these days, it works as a speakerphone and Bluetooth range is an amazing 100 feet.

Soft touch controls are on the side, and the on-off button on the back along with the charging and input ports.

Sound Quality

Now for the important part, the sound quality. Do the promises of upgraded sound quality live up to the manufacturer’s claims?

In a word, yes.  The OontZ Angle 3 Ultra speaker has the best sound quality available under $50 by a wide margin, and probably the best sound quality under $100. The OontZ Angle 3 Plus was always a very good speaker, but it had my mild sonic flaws (a little uneven with some kinds of music, and some occasional brightness)  that kept it from being compared with the very best small speakers. For only $49 it was a great value, but if you spent more you could get better sound.

With the OontZ Angle 3 Ultra,  you sound quality is competitive with any small speaker of the same size, regardless of price. You can spend more, but unless you go bigger you’re not going to get sound quality that rates as a dramatic  improvement.  It really is that good. Here’s what I had to say about it in my weekly newspaper column:

“OontZ speakers achieved market dominance by offering good sound at very affordable prices. The new Ultras go far beyond good, with high-end, top-shelf sound at the same very affordable prices. It is almost too cheap for what you get, and they sound fantastic with every genre of music from rock to classical, 1970s instrumental pop to R&B. As I listened, I kept thinking you could write Bang & Olufsen or Bose on the Ultras and double or triple the price, and people hearing them would say, “Wow, those high-end speakers are expensive, but it sure is worth it!”

The OontZ Angle 3 Ultra has ample, tight and satisfying bass, a nuanced, natural midrange, clear, clean treble, surprising spaciousness, near-perfect tonal balance and an extremely satisfying musical character that made it hard for me to turn it off and stop listening.”

OontZ Dual Stereo

You can also pair two OontZ Angle 3 Ultra to each other to play wirelessly from your device to two speakers. There are two dual modes:

Left Channel-Right Channel: The speakers serve separate left-right channels, providing  spacious stereo sound in your room.

Dual Stereo: Each speaker plays full-range stereo up to 100 feet apart. This is great for multiroom sound as well as playing music inside and outside from the same device.

Using the speakers in left-right mode not only provided decent soundstaging and palpable spaciousness,  the sound quality was enhanced as well. I was told that the speakers’ frequency response is adjusted for better performance in this mode, and it definitely takes the sound to a new level. Given a pair of OontZ Angle 3 Ultra speakers are under $100, it makes the value even more remarkable.


With sound that rates among the best speakers in its size class despite the $49.99 price, the OontZ Angle 3 Ultra rates as one of the best values in the audio world. The manufacturer’s claims of a big step up in sound quality are not mere puffery, and my hat is off to them for choosing to maintain a $50 price point when they could easily charge more.

Overall: 5/5

Performance: 5/5

Value: 5/5
