Beoplay M5 (right) would be my recommendation even against two pieces of M3's (left) - because the M3's doesn't support stereo pairing support anyway!
#Note: Find full B&O review list at the bottom.
Both Beoplay M3 and M5 are multi-room, stand-alone Wi-Fi speakers designed for home (stationary) use.
- If you're looking for a portable speaker, then stop reading this post right here and go check out my Beoplay M5 vs Beolit 20 article.
The main differences between Beoplay M3 vs M5 are related to design, sound quality and sound propagation.
I also contacted the Bang & Olufsen Customer Service about this (find mail history at the bottom) and put together all my findings here in this post.
Quick Summary
- Does M5 justify the extra price when compared to M3?
Depends on the positioning of the speaker.
If it's placed towards the center of the room, then the answer is clearly yes. I'd recommend the M5 my eyes closed.
If, however, it's going to be placed closer to the walls, then it might not worth the added price. I'm sure you'll still appreciate the better low frequency response - but does it worth the increase? Only you can decide that. To me (I'd define myself as an audiophile. Hello.), it does.
M5 is equipped not only with larger drivers & amplifiers, but also with MORE of them. On top of that, it propagates the sound on a 360 degree range.
As a result, although Beoplay M3 is still more than capable for most of us; Beoplay M5 delivers noticeably better sound quality - especially in the bass department (low frequency response).
Make sure to check out Beoplay M3 vs M5 chart on bang-olufsen.com.
M5 also offers wider sound propagation and more useful & slick speaker control options. Unlike M3, it's also compatible with Spotify Connect as well.
...then I'd strongly recommend you to check out their different color Kvadrat covers as well before buying - both for the M5 and for the M3.
Don't forget to check out B&O's very own AR app to see how both M3 and M5 would look like in your own home.
Sound quality & propagation
Let me tell you something right off the bat.
Room acoustics, particularly room dimensions and speaker positioning, will have an immense effect on sound quality.
The impact of the combination of these two is actually so strong that in most cases, it doesn't even make sense to utter a single word on sound quality without speaking of them.
This is why I'd hiiiiiiighly recommend you to check out this simple, 2D, online speaker placement calculator.
It's GOOOOLLLDDDDD. I've had an Acoustics & Audio PhD build this tool specifically for this purpose:
Default values:
- Ceiling height: 106 inches or 8 feet 10 inches or 2.70 meters
- Most standard ceiling height
- Listener's height: 32 inches or 2 feet 8 inches or 0.80 meters
- Average height of a sitting person
Central heights of speakers (measured from the ground) and examples to them:
- Soundbars: 30 inches or 2 feet 6 inches or 0.75 meters
- 8", 10" or 12" Subwoofers: 8 inches or 0.20 meters
- 360 degree speakers: 32 inches or 2 feet 8 inches or 0.80 meters
- Horizontal speakers: 32 inches or 2 feet 8 inches or 0.80 meters
- Floor standing speakers: 20 inches or 1 feet 8 inches or 0.50 meters
- Bookshelf speakers: 32 inches or 2 feet 8 inches or 0.80 meters
- Center speakers: 32 inches or 2 feet 8 inches or 0.80 meters
Side note: This tool can and will return inaccurate results for small, portable Bluetooth speakers such as JBL's Go Series. It will, however, deliver just fine for more powerful, packed bluetooth speakers such as this one.
ASAP Science made a video on the loudest and quietest rooms in the world. A mind blowing example of the importance of acoustics (time adjusted video).
Other parameters such as the age/materials of the building, the furniture & carpets in place, etc can and will, of course, have an effect on room acoustics, too. But much less.
Also...
Did you know you could also virtually hear any speaker online?
Crutchfield had recently created a tool that virtually simulates the sounds of many different speakers; such as those of SVS, Klipsch, KEF and B&W. Nothing will, of course, beat hearing the speakers in reality. But I'd still recommend you to give it a shot.
While you're at it, blast my Hidden Electronic Gems list to test them:
Anyways...
Both M3 and M5 are equipped with a unique software, which gets the speakers radiate the sound according to their positioning inside the room:
- Placed at the corner,
- Against a wall,
- Or right in the middle of the room (freestanding).
The speakers can't identify their positioning by themselves, though. You must be the one to introduce it to them manually.
M5.
However, designed to propagate the sound evenly on a 360 deg range (and hence the tower-like shape), M5 performs much better in this regard - especially in the middle of the room.
B&O seems to claim M5 does a good job in delivering stereo sound even when M5 is used as a single speaker.
They claim that M5 "leverages a proprietary Ambient Technology solution to create a true stereo sound experience from a single speaker".
Now in all honesty... I think that this is just a fancy sales language so I don't have any idea what that means.
Having said that, compared to multi-speaker systems, M5 indeed does seem to deliver almost equal stereo pairing and sound quality.
In the end, I think you might even find out that one piece of M5 sounds better than two pieces of M3's!
M5.
Speaking of which, unlike M5's 360 deg propagation, M3 only acts on a <180 deg range.
Depending on the distance and its location inside the room, there are times I find it as narrow as 120-150 deg.

Control & Ease of Use
The M5 speaker top is an aluminium disc that incorporates volume and connection controls that respond with a viscous dampened movement.
- Simply turn it to adjust the volume,
- Tap it once to have it play the last source,
- Double tap it to let Beoplay M5 join other speakers playing in your home,
- Press and hold to turn it on/off,
- Press and turn it to change the song.
You can also do it all with your phone as well.
*Video is time adjusted. Play it to see how the M5 shuffles through songs.
M3, on the other hand, has a simpler system for the same features where it uses buttons (one button for pause and two buttons for volume up/down) for said capabilities.
It isn't any less effective in this regard though - its capabilities remain the same.
Also, both lack a built-in Google assistant or Alexa.
Other shared features
M3 and M5 are multi-room Wi-Fi speakers. So they need power all the time.
It takes them about 1 minute to be completely set up. You can see this in M5 Manual [First-time setup] and M3 Manual [First-time setup] as well.
The reason they're advertised as multi-room speakers is because you can easily have them connect to other speakers in your home through the app in your smartphone.
Beoplay M3 still delivers quality sound but considering other alternatives out in the market, I don't think I can really recommend it unless you have a long, narrow home or love its stylish design.
Here's how the process works:
- Open the music app you prefer {Spotify, Deezer or Tune-in QQ Music (China Specific)}
- Choose the streaming service you prefer {Apple AirPlay, Chromecast, Bluetooth, Beolink, Spotify Connect [M5 only] or QPlay 2.0 (China specific) [M5 only]}
- Select the speakers from the list and tap play
Unlike other speakers like Beoplay A9, Beosound 2, Beosound Edge, etc; M5 and M3 are intended to fill smaller size rooms with their sound.
They can fill the bill for any room smaller than, say, 40 square meters. You can also connect both of them to a non-B&O TV or a sound system.
