Brane X
The bottom line
With its built-in subwoofer, the Brane X delivers a whopping bass response. If you're searching for a Bluetooth speaker to rattle your living room, this is the one to do it, although it comes at a premium. While it also offers decent clarity and instrument separation thanks to its stereo playback, at the end of the day, the Brane X is still a portable Bluetooth speaker with limitations unless you buy two.

The Brane X, the singular flagship product available from sound technology company Brane Audio, has caught the attention of bass lovers abroad. As the first portable Bluetooth speaker to feature a built-in subwoofer and boast “industry-disrupting tech,” is Brane Audio changing the game? We couldn’t resist putting this fancy speaker through its paces in this Brane X review.

Editor’s note: this is the first version of the article. Updates will follow as the market changes.

About this Brane X review: We tested the Brane X over a period of 1 week. It was running firmware version 2.0.1723693359, and the Brane X app ran version 1.0.7 (Build 35). SoundGuys purchased the unit for this review.

With its built-in subwoofer, the Brane X is for those after a beefy Bluetooth speaker that offers a substantial amount of low-end bass response in a small (but heavy) package. While it’s fairly portable and protected from the elements, its Wi-Fi capability makes it a great speaker for the living room or basement.

What’s it like to use the Brane X?

The Brane X features a built-in sub-woofer.

There’s no way around it; the Brane X is a beast of a Bluetooth speaker. Weighing 3.5kg or 7.7 lbs, it’s not a toss-it-in-your-backpack speaker, although it’s still pretty portable thanks to the rubberized handle attachment. Inside, you’ll find Brane’s “Repel-Attract-Driver” (RAD) subwoofer, which measures 6.5″ x 9″ and is accompanied by two mid-range drivers and two dome tweeters. The Brane X gets decently loud considering its toaster-shaped size and provides enough bass to help you meet your nearest neighbors if you haven’t already.

The touch controls are quite sensitive.

There are touch controls are on the top of the unit, which are extremely sensitive. The lightest tap or even an accidental swipe will register a command, one more reason I prefer tactile buttons. I was also disappointed to discover that your playback controls are limited to only volume adjustments. There are no physical controls to play, pause, or skip forward or backward.

The subwoofer is downward-firing and protected by a flexible piece of plastic on the underside of the enclosure. The front and sides are wrapped in durable fabric, similar to what you find on a JBL Charge 5 speaker. Around the back, you’ll find your AC power port, 3.5mm aux-in, and power button. In terms of protection from the elements, the Brane X is IP57-rated, meaning it’s protected from dust and submersible in water up to a meter for 30 minutes; although you better snag it quickly, it will for sure sink to the bottom of whatever body of water it falls into.

The Brane X operates via touch controls. As mentioned, it offers no physical play, pause, or skip forward/backward control. Below is a breakdown of how they operate:

Should you use the app for the Brane X?

I recommend downloading and installing the Brane app to use with the speaker. You’ll need it to set up your Wi-Fi connection and “Hey Alexa” if you choose, but it also gives you access to a 5-band customizable EQ so you can personalize the sound of the Brane X speaker a little further. Here, you’ll also be able to access any firmware updates and modify some of the speaker’s default settings, like adjusting LED brightness or turning off the unit’s start-up phrases.

How does the Brane X connect?

The Brane X is three for three when it comes to connection options. You can connect your device to the Brane X via Bluetooth 5.1, Wi-Fi, or 3.5mm audio cable. Unfortunately, the Brane X does not offer multipoint connection and is SBC only. There are no higher bitrate listening options.

Connecting the Brane X to your device over Bluetooth is easy and follows the usual steps:

  1. Once powered on, single-tap the Bluetooth button.
  2. Open Bluetooth settings on your phone and select “Brane-XXXXX”
  3. Download and install the Brane app to control the Brane X speaker further.

As mentioned, you will need the Brane X app to connect your speaker over Wi-Fi.

How long does the Brane X’s battery last?

Brane states that you can achieve 12 hours of playback at “moderate volumes” off a single charge, and the unit takes 3 hours to full charge. Keep in mind that if you’re cranking your tunes and running your bass levels at “High,” you might not quite make it to 12 hours, and you’ll need to find an AC outlet to charge the speaker back up. The Brane X does not charge via USB.

How does the Brane X sound?

The Brane X sounds full and clear at reasonable volumes, with a low-end response you can feel.

Multi-Dimensional Audio Quality Scores (MDAQS)

The chart below shows how the sound of the Brane X was assessed by the Multi-Dimensional Audio Quality Score (MDAQS) algorithm from HEAD acoustics.

This chart shows the MDAQS results for the Brane X in High Bass mode. The Timbre score is 3.8, The Distortion score is 2.5, the Immersiveness score is 2.6, and the Overall Score is 3.3).
The Brane X pulls above-average results for its category.

When it comes to MDAQS, the Brane X receives an overall score of 3.3 with the high bass setting engaged. This is just slightly above average for portable Bluetooth speakers, but nothing to worry too much about. For reference, the Sony ULT Field 1, a less powerful and more packable speaker, obtained an overall score of 3.1.

Our simulated panel of listeners generally prefers a good amount of low-end. When comparing the MDAQS results of the other bass settings, we see a gradual decrease in their respective timbre, immersiveness, and overall scores. However, we see an improvement in Distortion scores as the bass level decreases.

Timbre (MOS-T) represents how faithfully the speaker reproduces the frequency spectrum and temporal resolution (timing information).

Distortion (MOS-D) represents non-linearities and added noise: higher scores mean cleaner reproduction.

Immersiveness (MOS-I) represents perceived source width and positioning: how well virtual sound sources are defined in three-dimensional space.

See here for an explanation of MDAQS, how it works, and how it was developed.

Can you use the Brane X for phone calls?

While the Brane X offers voice assistant, it does not contain a speakerphone function for taking phone calls.

Should you buy the Brane X?

It’s expensive, but you can’t beat the bass response, considering its size.

If you’re bass-hungry, okay with the weight, and can afford the hefty price tag of this speaker, the Brane X will deliver a consistent low-end rumble for your next gathering, indoors and outdoors. Just keep in mind that, at the end of the day, as overdesigned and overbuilt as this speaker is, it’s still a portable Bluetooth speaker.

While it can pump up the jams with a quality bass response for a living room or basement party without issue, for any gathering larger than that, you’d most likely want a second Brane X speaker for proper stereo performance.

What should you get instead of the Brane X?

It’s officially a party once BassUP is engaged.

If you want some boom but are on a budget, check out the less expensive Anker Soundcore Boom 2 Plus. ($249.99 at Amazon) This party speaker is much more affordable, not to mention it has built-in LED lights on its passive radiators that pulse and change color in sync with your music. While it doesn’t quite match the bass response of the Brane X, it’ll get you close for a fraction of the price.

The JBL Xtreme 4 retains its IP67 protection rating.

The JBL Xtreme 4 (on the product's website) is also worth a look. This rugged speaker features an IP67 protection rating, companion app support, and decent bass for your next gathering, indoors or out. Thanks to the JBL Portable app and its 5-band EQ, you can personalize the sound of the Xtreme 4. Lastly, the Xtreme 4 offers 24 hours of battery life and features swappable battery packs. You can purchase a second battery pack from JBL to ensure you never run out of juice.
