The selection of multiroom Bluetooth speakers is enormous. The B&O Beoplay M3 stands out from the crowd with its design. But, is the sound outstanding too?

At first glance, the B&O Beoplay M3 Wireless Speaker isn’t as big or impressive as some of its predecessors, like the Beoplay M5. However, depending on the size of your living space, the smaller, minimalist design could also be suitable for medium-sized rooms.

B&O Beoplay M3 is available in two colors, black with an aluminum grille cover or, of course, with a light gray fabric. In addition, the front cover is interchangeable, so you can customize the M3 to suit the mood of any room.

The case itself is made of sturdy, anodized aluminum for improved acoustics. In addition, the speaker weighs only 1.46 kg, so it is not difficult to transport it. There is a Wi-Fi signal LED, power indicator, power button, volume buttons on the back, and a play/pause button. The speaker also has a standby button, but I find it difficult to reach.

The lower area is the power input, the setup buttons, a micro USB port, and a 3.5mm jack input. The M3 can also be wall-mounted using a small screw connector on the bottom of the unit. The only downside is the power cord, which is located on the back of the speaker. At first glance, the design is minimalistic and modern for me.

It doesn’t take up much space for its size (5.5″ x 4.5″ x 6.2″), has a sturdy, cylindrical body, and looks more like a piece of decorative art than a multi-room speaker from certain angles. For the design and aesthetics, the M3 gets a big thumbs up.


  • Great sound despite the small size
  • Quick and easy pairing via Bluetooth
  • B&O app with additional features
  • Speakerphone


  • No wall mount included

What is included?

The scope of delivery includes the Beoplay M3 itself, the removable fabric aluminum grill cover, a power cable, and the user manual. One addition I would have liked to see included a wall mount. So, if you want to mount the M3 on a wall, you have to buy an original Bang and Olufsen bracket.

The app

Beoplay M3 is packed with various features that are very user-friendly and surprisingly customizable. First and foremost, the M3 is wireless and can be operated via Wi-Fi via a fully integrated Bang & Olufsen app.

The Bang and Olufsen app allows the M3 to be connected to other Bang and Olufsen devices such as the A6, A9, or M5 to create a ‘multi-room’ experience. The M3 is also compatible with Apple Airplay and Bluetooth and even has Google Chromecast built-in.

This makes it possible to use your preferred streaming service and play your favorite music. However, one of the most impressive parts of the M3 is the surround sound. The speaker can be set to play the optimal music in a corner, against a wall, or in the middle of the room directly from the Bang & Olufsen app.

Through various settings in the app, the sound is modified for the best results. At first glance, the list of features might seem overwhelming for those just looking for a speaker with great sound quality.

But once you took the time to learn how this little powerhouse works and what it can do, it was easy for me to see how valuable some of those hidden extras are.


The M3 can be overwhelming for someone who wants to sync their smartphone and start playing right away. The app offers most of the functionality and is relatively easy to use. However, you should read the enclosed manual to know what the speaker can do.

The connection is via Bluetooth with a smartphone, and then use the app. Sometimes apps like this can be tedious and create a barrier to efficiency with electronics, but Bang and Olufsen’s interface is relatively easy as long as you have the patience. The initial installation was easy and worked flawlessly.

For those who aren’t impressed with all the bells and whistles and might even think the price is too high for a speaker of this size, the M3 might not be the best choice. However, after reading the manual, I felt it became easier and easier to use. Before long, both the app and the speaker itself became fairly intuitive. Once I set the M3 up, I could easily play a few pieces of music.

How is the sound quality?

Beoplay M3 scores with its size when it comes to sound quality. There is a full auditorium sound with a 3.75″ woofer, a ¾” tweeter, and two 40W amplifiers.

In my opinion, the sound volume is more than enough for small to medium-sized rooms. However, the bass was a bit too noticeable and overwhelming for me. Still, by selecting one of the room optimization settings via the Bang & Olufsen app, I was able to find a setting that was a bit mellower.

There are three ‘Sound Profile’ settings, Free, Wall, and Corner. Alternating between them mainly affects bass performance, with Free being the strongest and Corner being the weakest.

Via a separate EQ setting in the Beoplay app (tap the speaker image; it’s not obvious it’s there) called ‘Tonetouch.’

I find it necessary to toggle between the Tonetouch presets or turn them off depending on what I listen to (different types of music, podcasts).

Sound test of B&O Beoplay M3

After some tweaking, I found that setting the M3 in Corner mode delivered the best, sharpest sound, cutting out some of the excessive basses that were present when first turned on. Again, this will ultimately depend on your listening habits, but it’s certainly good to know what options are available to tweak the sound the way you like it.

I also found that the clarity was extremely good at higher volumes, with minimal clipping or vibration from the speaker itself. The most important thing about the M3 is that it’s not intended to be the main audio source. Instead, it is offered as an entry-level multi-room speaker paired with multiple other devices to provide an immersive experience.
