Cambridge Soundworks Oontz Angle 3xl Characteristics

The Oontz Angle 3XL looks ultra and feels a bit louder and more durable than other Oontz Angle speakers. They have used brushed aluminum for some parts, which suggests it will need some kicks.

There are 4 drivers (2 woofers and 2 tweeters) inside the speaker with a maximum combined output power of 24W. The speaker also has 3 passive bass radiators for better bass response.

The controls are over the top and they look really cool. One thing you didn’t find on other speakers is the dedicated track button. Most Bluetooth speakers (even the most expensive ones) today don’t have dedicated track buttons. On some speakers, you can use the play/pause button or the volume button to change the track (play/rewind), but there are only a few dedicated buttons. This is not a great benefit, but it is worth noting.

The Angle 3XL Ultra has Bluetooth 4.2 and has a Bluetooth range of up to 100 feet (without interruption) which is quite impressive. NFC instant coupling is not supported. The speaker will always try to reconnect the last paired device. The Angle 3XL Ultra also has an AUX port for connecting non-Bluetooth devices.

The speaker supports a daisy chain connection (double pair) and can connect two speakers wirelessly and receive stereo sound or loud sound (INDOOR VS OUTDOOR mode). You cannot pair multiple Angle 3XL Ultra speakers simultaneously.

The Angle 3 XL Ultra has a large battery that can deliver 8% (up to 10 hours) at 50% volume. A recharge is approx. for hours.

This is a replaceable battery. You can buy batteries for less than $ 20 from the manufacturer. The replacement process is quite simple: all you have to do is open the battery compartment, take out the old battery, insert the new one, and close the battery compartment.

Angle 3XL Ultra has a power bank port for charging. You can charge your phone or tablet while listening to music, which is very convenient and makes this speaker more competitive.

The OontZ Angle 3XL Ultra is IPX5 certified, which means it is waterproof. It cannot flourish in water and it cannot swim, but it can survive some splashes of water. The manufacturer also claims that it is dust-proof, but it does not have a dust-proof rating.

The built-in microphone has become a standard feature for portable Bluetooth speakers and you can also find it on the Oontz Angle 3 XL Ultra.

Construction and design

The 3XL Ultra Angle measures approximately 11.5 x 4 x 4 inches. It uses a triangular design typical of the OontZ series. Each edge of the triangle is easily rounded. And the 3XL weighs around 2.4 pounds. It’s a bit heavy for a Bluetooth speaker, but it’s not heavy enough to want to carry one around. However, each end of the 3XL has been slightly removed, giving you a firmer grip for carrying.

The chassis is largely made of ABS plastic, which helps make the OontZ Angle 3XL slightly im

pact resistant. However, the relative heaviness of this speaker is not good for his chances of survival, but he must face a serious fall.

Additionally, the chassis is serially sealed, providing IPX5 certification. This allows the 3XL to resist dirt, dust, rain, and sweat. You can also take Cambridge SoundWorks Oontz Angle 3XL Ultra in the shower or spray it with a hose if you’re careless. But it’s not going to handle the presentation, so you’ll want to keep it out of the pool.


This is a loud 100 dBa volume that surprises you because you normally need a large set of internal components to produce such a loud sound. Even better, at high volumes, slight distortion is barely noticeable and the sound quality is high.

The combination of two woofers and two tweeters adds clear and detailed mids and highs. The highs are crisp and the tones are light; Overall a well-balanced, natural sound.

You may be disappointed in the richness of the bass. The really deep bass sound comes with a separate subwoofer housed in a chassis. The three passive bass radiators produce some bass, but it is not as rich as you would find with a subwoofer and lacks punch.

When the speaker is switched to outdoor mode, the bass loss is more noticeable. The sound is focused on projecting outward with bass radiation which is mostly unused. Wide, open spaces do not need to be filled indoors, so when you enter indoor mode, the bass tones are strong.

Device compatibility

Going back to the OontZ Angle 3xl, it goes without saying that this Bluetooth speaker is compatible with iOS and many smart devices using Amazon’s operating system that are Bluetooth enabled.

Coupling problems can occur when you connect multiple existing phones, this is also a recurring problem with other Bluetooth speakers, where building a new device can become a tricky business at first.

As Bluetooth technology changes frequently, I think there may be additional problems due to the use of digital devices. Most iPhone or Android connected to this speaker instantly without any problems.

Battery duration

Although Cambridge SoundWorks OontZ Angle 3XL Ultra actually carries a much larger battery, it also uses several larger audio drivers. Expecting battery life depends on a number of factors, especially how much you use.

But Cambridge SoundWorks OontZ Angle 3XL Ultra is capable of lasting around 8 hours on a single charge. The 8 hour estimate can be reduced to 6 hours in inhumane conditions. But it is certainly sufficient for most excursions. It takes approximately 4 hours to recharge the battery from an empty state. The top battery LED will turn red during charging and a steady light will appear when this happens.

Plus, unlike most portable Bluetooth devices, you can play music while the 3XL Ultra is charging.

Is best suited to use

The Ultra is a speaker found both indoors and outdoors.

Ultra-high-quality audio will fill any size room with sound. And there will be no problem in listening to music in chat and in the party bubble.

Getting it out is not a problem. After all, it is portable and has an outdoor mode to eject sound to cover a beach, pool, or block area. Turning on the volume will produce a strong but quality sound with little noticeable distortion, although the bass may not be as powerful and vibrant as you want it to be.

If you want to increase the sound, you can connect the 3XL Ultra to each other. You may want to invite neighbors to your party to avoid complaints.

Other things

Since it was first released, Cambridge Soundworks Oontz Angle 3xl has been remade. The first thing is to update the speaker online. The process is quite simple and detailed installation instructions are included. But you really want to download the update asap.

Once you update the 3XL firmware, a lot of things improve immediately. You get better playback performance with its 3.5mm connection, better equalizer capability for bass output and better overall volume stability. The update also fixes an issue with audio playback delays that may occur while watching a video.

The Cambridge Soundworks Oontz Angle 3xl includes a dual voltage power adapter and a 3.5 mm audio cable. The included audio cable is about 5 feet long, and using it you can easily add a few more hours to your battery life.

Based on tests and information collected to review this OontZ Angle 3 portable Bluetooth speaker, it is capable of delivering crisp and clear sound with decent bass. I would gladly put this product in the top 10 best portable Bluetooth speakers in the world.

It is difficult to argue against prices below thirty dollars. I think it is a very high priced speaker at this price. I intend to keep this Bluetooth speaker because I like it. Don’t be fooled by its small size, as it is designed to produce excellent sound from most digital devices.
