OontZ Angle 3XL Ultra is the upgraded version of the OontZ Angle 3XL. This is the largest speaker from the very popular and very affordable OontZ Angle series of speakers made by Cambridge SoundWorks.

You have probably heard of the OontZ Angle speakers before and you would be able to recognize one since they all have that unique triangular design. OontZ Angle 3XL Ultra features the same design but it still stands out because of the size and especially because of its features and performance.

This large speaker is, in many ways, better than any other OontZ Angle speaker. The build quality is significantly improved – the edges are made of brushed aluminum and some parts are also reinforced with rubber which makes it suitable for outdoor use. The controls are more intuitive, easier to use, and they look better. OontZ Angle 3XL Ultra features Bluetooth 4.2 and has a Bluetooth range of 100ft, it can be wirelessly paired with another Angle 3XL Ultra for louder or stereo sound, it features large replaceable battery which can deliver more than 8 hours of music playback at 50% volume, it also has a powerbank USB port, and it’s IPX5-certified. In terms of audio performance, this one delivers clear, detailed, and rich mids and highs, and it is incredibly loud.

OontZ Angle 3XL Ultra Review

The OontZ Angle 3XL Ultra is a portable Bluetooth speaker that delivers a powerful, clear sound with deep bass. It has a long battery life and can connect to all Bluetooth devices. It is perfect for outdoor activities, parties, and travel. It is easy to carry around and easy to connect. It can go loud and can play for a long time.

When it comes to things that could discourage you from buying this speaker, it’s important for you to know that OontZ Angle 3XL Ultra doesn’t deliver very deep and powerful bass and it’s not the best choice for a party speaker even though it’s very loud. Also, the size and price could be problematic. In terms of size, it’s comparable to JBL Xtreme and Xtreme 2 (although JBL speakers are much heavier). The price varies from $110 to $130, so it’s not a cheap Bluetooth speaker.

Just like any other OontZ Angle speaker, Angle 3XL Ultra features unique and distinctive triangular design. Due to this specific shape, you will recognize OontZ Angle speaker among a bunch of others. The manufacturer could’ve done a better job when it comes to color choices since there’s only black version available.  

Compared to its predecessors, Angle 3XL Ultra features better build quality. Cambridge SoundWorks used more premium materials (like brushed aluminum) and made it look better, but it’s still doesn’t look as premium as some other speakers within the same price range (up to $150).

Another important thing you should know about this speaker is that, unlike other OontZ Angle speakers, Angle 3XL Ultra can only be placed horizontally.

Front and back side of the Angle 3XL Ultra are covered with a black semitransparent grille. All the drivers (two 2.75-inch woofers, two 0.5-inch tweeters) are located on the front side. On the back side, there’s only one passive bass radiator.

Oontz Angle 3XL Ultra features two additional bass radiators on the left and right sides. So, 3 passive bass radiators in total. They are supposed to enable impressive bass response, but unfortunately, that’s not the case (we will discuss this issue in the Sound Quality section).

Passive bass radiators are located on the left, right, and rear panel

On the rear panel, right at the bottom, you will see a rectangular rubber flap protecting the inputs and one switch. There are 3 inputs – USB powerbank port (for charging your phone or any other device), AUX input, and proprietary charging port. On the left side, next to the USB powerbank port, there’s a small INDOOR/OUTDOOR switch. You can use this switch to choose stereo (INDOOR) mode or dual sound (OUTDOOR) mode when two OontZ Angle 3XL Ultra speakers are paired together.

The control panel is located on the top. There are 7 control buttons – power, Bluetooth/phone, 2 track buttons, play/pause button, and 2 volume buttons. You will also see three LED indicators (charging, Bluetooth, and daisy chain) and a built-in mic (between the Bluetooth button and previous track button).

Oontz Angle 3XL Ultra looks and feels a bit stronger and more durable than other Oontz Angle speakers. They have used brushed aluminum for some parts, which gives the impression that it can survive a few kicks.  

Inside the speaker, there are 4 drivers (2 woofers and 2 tweeters) with a combined peak power output of 24W. The speaker also has 3 passive bass radiators for improved bass response.

As we have already said, the controls are on the top and look really nice. One thing you won’t find on other speakers are dedicated track buttons. Most of today’s Bluetooth speakers (even more expensive ones) don’t have dedicated track buttons. On some speakers, you can use the play/pause button or the volume buttons to change the track (play previous/play next) but only a few have dedicated buttons. It’s not such a huge advantage, but it’s worth mentioning.

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

The speaker supports daisy chaining (dual pairing) and you can wirelessly pair two speakers and get stereo sound or louder sound (INDOOR VS OUTDOOR mode). You cannot pair multiple Angle 3XL Ultra speakers together.

Angle 3XL Ultra features large battery which can deliver more than 8 hours (even up to 10h) at 50% volume. The recharge takes approx. 4 hours.

Unlike many other Bluetooth speakers on the market, and unlike other OontZ Angle speakers, this one has a replaceable battery. You can buy the battery for less than $20 from the manufacturer. The replacement procedure is quite simple – you just have to open the battery compartment, take out the old battery, insert the new one, and close the battery compartment.

Angle 3XL Ultra features a powebank port for charging. You can charge your phones or tablet while listening to music which is pretty convenient and makes this speaker more competitive.

Built in USB Power Bank

Thanks to its build quality, OontZ Angle 3XL Ultra is IPX5-certified which means that it is water resistant. It’s not submersible in water and it cannot float, but it can survive a few splashes of water. The manufacturer also claims that it is dustproof but there’s no dustproof rating (if it was tested and certified as dustproof it would be IP65-certified and not IPX5-certified).

Built-in mic has become a standard feature for portable Bluetooth speakers and you can find it on Oontz Angle 3XL Ultra, too.


We’ve had no major complaints regarding the performance, but there are a few things we would like to mention.

The control buttons are very simple and very intuitive. You don’t even need the manual to figure out how to pair the speaker with your phone and play the music but you should definitely read it if you want to pair two speakers together for stereo/louder sound. In short, in order to pair 2 speakers together, you have to pair your phone with one speaker first (that speaker becomes the main speaker). After you turn on the other speaker, the speaker will go to pairing mode. You are not supposed to pair that speaker with your phone. You just have to press the play/pause button on the main speaker for 5 sec and, in a few seconds, the speakers will be paired. Depending on the position of the INDOOR/OUTDOOR switch, you will get either stereo sound (the main speaker is the left and the other speaker is the right channel), or dual stereo sound (both speakers play the same audio). For stereo (INDOOR) mode, you should select the left position, and for dual stereo (OUTDOOR) mode, you should select the right position.

Bluetooth works exactly as advertised. Pairing is simple and takes a few seconds and the Bluetooth range is quite impressive. You can get even more than 100ft without obstacles (it depends on the phone you use). One thing this speaker doesn’t support is the multi-host feature so you cannot pair two or more devices with the speaker simultaneously. Angle 3XL Ultra is compatible with all kinds of Bluetooth-enabled devices (Android, Apple, Windows) and it’s also compatible with Amazon Echo and Echo Dot.  

The battery is great. One thing we really like about this manufacturer is that they state the circumstances under which the playtime was measured. The advertised playtime is 8hours at 60-70% volume. In reality, you can get more than 8 hours (up to 10 hours) at 50% volume.

The built-in mic delivers an average performance. It’s neither better nor worse than the mic on some other similarly priced speakers. It does muffle your voice a little bit, but it’s far from unusable.  

Another great thing about this speaker is that Cambridge SoundWorks allows you to perform the firmware update and eliminate some glitches. One of the most important updates is supposed to eliminate/reduce the audio delay when watching movies. Unfortunately, the delay is noticeable even after the update. It’s not as distracting as with other Bluetooth speakers but it’s definitely noticeable. After all, this speaker doesn’t feature aptX support which is the most important thing for eliminating audio delay.

Sound Quality

There are some good and some bad things about this speaker’s audio performance, but it’s mostly good.

The only noticeable issue is the lack of bass. It’s not like it doesn’t exist, but it’s weak and lacks impact.

On the other hand, mids and highs are perfectly clear and detailed. They are nicely balanced and sound quite natural. Vocals are slightly elevated.

The clarity is one of the greatest qualities when it comes to sonic performance. This speaker really keeps it together, even at high volumes. There’s a barely noticeable distortion at full volume, but it’s not distracting, and it doesn’t ruin the listening experience.

The volume is another highlight. OontZ Angle 3XL can get really loud, louder than JBL Extreme.

Stereo separation is almost nonexistent, but luckily, you can always pair two speakers, and get much better separation.

The Competition

The number of possible choices when it comes to portable Bluetooth speakers under $150 is huge and you should definitely do your own research and compare Angle 3XL Ultra with other speakers. The following three speakers are our choice.

Fugoo Style SFugoo Style S

Fugoo Style S has a similar shape and it’s basically priced the same as Angle 3XL Ultra, but it’s much smaller. There are a few versions of Fugoo speaker, but Fugoo Style S is by far the most elegant one (thanks to its wrapping) and it looks better than Angle 3XL Ultra.

Angle 3XL Ultra offers more control, has more buttons, and it’s easier to use. Fugoo Style S has only three control buttons.

Fugoo Style S is completely waterproof, dustproof, and shockproof, and it can float (IP67-certified). Fugoo Style S definitely wins when it comes to build quality.

Fugoo Style S has a smaller battery but delivers longer playtime than Angle 3XL Ultra (15 hours compared to 8-10 hours).

Both speakers feature Bluetooth 4.2 and can be paired wirelessly with another speaker.

Angle 3XL Ultra features USB powerbank port and Fugoo Style S doesn’t.

Angle 3XL Ultra delivers much fuller, more detailed, and louder sound than Fugoo Style S.

JBL Charge 3JBL Charge 3

JBL Charge 3 is cheaper than OontZ Angle 3XL Ultra and, in our opinion, it looks better.

JBL Charge 3 is also more rugged and it features IPX7 rating (completely waterproof) while Angle 3XL Ultra is water resistant (IPX5 rating).

Charge 3 features 6,000mAh battery and delivers longer playtime compared to Angle 3XL Ultra (20 hours compared to 8-10 hours).

They both feature Bluetooth 4.2, but Angle 3XL Ultra has a slightly larger Bluetooth range. Angle 3XL Ultra can be paired wirelessly with only one speaker, while you can pair up to 100 JBL Charge 3 speakers together.

Both speakers have USB powerbank ports. Also, they both have built-in mics.

Angle 3XL Ultra delivers louder, cleaner, less distorted sound, but JBL Charge 3 delivers stronger and punchier bass.

Altec Lansing OMNIJACKETAltec Lansing OMNIJACKET

Altec Lansing OMNIJACKET also has a specific and recognizable design but we really can’t decide which one looks better. OMNIJACKET definitely comes in more interesting colors and it’s much smaller. It’s also significantly pricier.

Altec Lansing OMNIJACKET is much more rugged than OontZ Angle 3XL Ultra. It’s IP67 certified (waterproof, dustproof, shockproof, and it floats).

Altec Lansing OMNIJACKET delivers much longer playtime (50 hours compared to 8-10 hours).

Both speakers can be paired with another speaker of the same kind but Angle 3XL Ultra has two modes (stereo and dual sound) while Altec Lansing OMNIJACKET allows only dual sound.

Both speakers have built-in mics.

Angle 3XL Ultra delivers much punchier, louder, and more detailed sound than Altec Lansing OMNIJACKET.

Frequently Asked Questions

Does OontZ angle 3 Ultra have a microphone?

Yes, the OontZ Angle 3 Ultra has a built-in microphone. The mic is located between the Bluetooth button and the previous track button. It can muffle your voice a little but is not completely unreliable. It is of average quality, like most built-in mics in other speakers.

How long does the OontZ angle 3 last?

The OontZ Angle 3 Ultra delivers between 8 to 10 hours of listening at 50% volume and a battery life of up to 20 hours. Recharging takes a little time, though, as it takes approximately 4 hours to reach full charge. Unlike most other Bluetooth speakers, it features a replaceable battery.

How loud is the OontZ angle 3 Ultra?

The OontZ Angle 3 Ultra has a frequency range of 150 Hz to 140 kHz. It has a relatively low bass reproduction, so your audio might lack the thump and rumble you’re looking for. Because of this, the OontZ Angle 3 Ultra is not considered to be very loud.

Final Thoughts

Oontz Angle 3XL Ultra is an awesome portable outdoor Bluetooth speaker. It’s very loud, it features Bluetooth 4.2 with 100ft range, it can be paired with another Angle 3XL Ultra for stereo/louder sound, it’s IPX5-certified, it has a large replaceable battery, it delivers 8-10 hours of playtime, and it has a built-in powerbank port. It also has its flaws (size, price, lack of bass) but it’s still very competitive and it’s one of the best choices under $150. The only real flaw is the lack of bass and if you don’t mind this, you should certainly try this amazing speaker.

    I own this speaker and it’s smaller “brother/sister”.
    If a user has a problem with the “bass response” of any Bluetooth speaker, the simple fix is to put the speaker on a floor/counter/shelf close to a wall or in a corner.
    Any Audio Engineer or Musician will tell you this.
    It enhances the loudness of the speaker as audio waves will be reflected and enhanced by the walls.
    It’s worked great for Bose for over 40 years.
    The most overrated and mid-range sounding speakers ever made.

    I have many other speakers in my collection from Bose, Sony, UE, Anker…..

    Here is my quick review for 3xl ultra:

    For this price of money sound quality is fine. I connect him very easy to my devices. Battery life is also good, I did not measure how much I needed to completely fully charged. Maybe 2 hours, what do you think? My next target is OontZ Angle 3 Ultra 🙂

    Nice review James!
