OontZ Angle Solo Review

By TechGuru Review Source

Being the smallest and most portable of the series, the Angle Solo is intended to be something you can shove in your pocket. Or a speaker you can wear around your wrist and barely notice it’s there. Though every smaller speaker faces unique design challenges, the Cambridge Soundworks OontZ Angle Solo can provide equally unique solutions.

Build & Design

Measuring 2.8 x 3.9 x 2.75-inches, the OontZ Angle Solo is nothing if not portable. Made with a triangular design, the Angle Solo is both resistant to being knocked over and resistant to rolling. Its lightweight body weighs about half a pound. On its outer edges, the OontZ Angle Solo has two mounting loops that can also be used with a carrying strap.

Portable audio equipment isn’t tucked-away inside a dusty cabinet, it’s something you carry around with you. That being the case, your Bluetooth speaker might border on becoming a fashion accessory. The Cambridge Soundworks OontZ Angle Solo is available in black, red, blue, and white. And the entire OontZ series uses a similar color scheme.

The exterior chassis of the Angle Solo is mostly composed of ABS plastic. That allows the OontZ Angle Solo to be impact resistant, but it’s not certified as shockproof. It’s most likely going to survive from hands-distance or table-distance falls, plus or minus some minor scratching. The exterior feels smooth in your hands, but isn’t intended to hold up against abuse.

Waterproof Protection

Toughened plastic casing allows for the Cambridge Soundworks OontZ Angle Solo to provide an IPX5 certification. That indicates a design which is protected against splashes, rain, sweat, dirt, dust, grit, and similar minor agitations. You could even take the OontZ Angle Solo into the shower with you.

But IPX5 does not indicate protection against submersion. If you dropped the speaker in a deep puddle and picked it up promptly, it would most likely survive. You just don’t want to tempt fate by intentionally submerging it. Nevertheless, the IPX5 protection allows the OontZ Angle Solo to be a fairly good choice for taking to the beach, and a reliable companion for unpredictable weather.

Analogue Control Buttons

On its left side, you’ll find some easily identifiable analogue buttons. Buttons labeled as +/- can be used to adjust volume levels and skip around through tracks. The play button, power button, and Bluetooth button are just as easily identified. Though none of these buttons are particularly special, they do provide all the control you need for a Bluetooth speaker.

Microphone Quality

Adjacent to the control buttons, Cambridge Soundworks OontZ Angle Solo has smartly positioned its onboard microphone. Unfortunately, the OontZ Angle Solo uses a microphone that’s somewhat underwhelming, or terrifically average. It brings absolutely zero special features to the table. There’s no adjustable mic gain, no built-in support for additional services, no special noise cancellation abilities.

There’s really nothing special about the microphone at all. With all that said, when you’re inside the kind of environment where you could take a phone call, you’ll find the included microphone is perfectly adequate. With respect to call clarity, Bluetooth and the Angle Solo speakers can do most of the heavy lifting. It’s only when you begin to expect more from the microphone that you’ll face disappointment.


The OontZ Angle Solo makes a wireless connection through Bluetooth 4.2, allowing it to quickly connect to your smartphone, tablet, and similar Bluetooth enabled devices. Most Bluetooth speakers in this price range will restrict your connection distance to about 30 feet. That doesn’t sound so bad, until you realize that the distance drops in half when you place an object between the speaker and transmitter.

The OontZ Angle Solo provides connectivity up to 100-feet. While you need line of sight to really achieve 100ft connections, this wider connection distances also translates into much more consistent connectivity at with modest distances.

Sound Techniques

People have rightfully come to have low expectations from small speakers. Nobody has ever opened a singing birthday card and felt as though they were experiencing movie-theater audio quality. When you’re dealing with smaller equipment, a smaller power source, and a lower budget, there’s only so much that can be done with audio quality. But there are things that can be done.

The Bose brand may serve as a good example. People who criticize Bose often make the same point. What Bose does is take inexpensive audio components, which are really nothing special, and try to make them sound great. Instead of fine-tuning the hardware itself, they do this with software enhancement. Or they use psychoacoustics to develop audio tricks.

Cambridge Soundworks takes a somewhat similar approach with the OontZ Angle Solo. The underlying neodymium drivers within this speaker are unremarkable. But the so
