OontZ is a sub-brand of parent company Cambridge SoundWorks. Cambridge SoundWorks was founded in 1988 with a mission to design well-priced high quality audio products. In 1997, they were purchased by Creative Labs, but still sell OontZ products under the Cambridge SoundWorks trademark.

Bluetooth speakers have been gaining traction among many eager to reap their benefits. They typically are wireless, portable and sound great! This is a recipe for success when it comes to making a good Bluetooth speaker.

Today, I’ll be taking a look at the OontZ Angle 3XL PRO edition speaker. This speaker has many premium features while still maintaining a very good price. Cambridge SoundWorks works to keep a value oriented price-point that does not compromise on quality.

Final Thoughts


If you couldn’t tell already, the OontZ Angle 3XL Ultra Portable Bluetooth Speaker is a great option for a Bluetooth speaker.

It is quite larger than the original Angle 3 Ultra, however the 3XL and PRO add a significant amount of speaker power. The sound is awesome. Using two speakers together creates a really good stereo effect.

You can download the OontZ App to help adjust bass and treble to your liking. I prefer a bit heavier bass and treble, but not where it is overpowering (about 60-70% of max). There isn’t a lot of speakers that allow customization in the more budget friendly price range so this feature is very useful.

While the Ultra PRO is more expensive than the regular Ultra, it is 100% worth the extra price. You can more than double the speaker for the money and you won’t be disappointed.
