As a company with a high reputation in the production of multiroom speakers, B&O did not compromise with the features in their Beoplay M3, except the unalterable mono output attribute and the overwhelming bass line at high volume. Beoplay M3 price ($299.00) is considered cheap by most users summing up the features. And as the cheapest so far from B&O, most Beoplay M3 reviews agree that the audio quality, full-packed features which includes Google Assistant, and portability are impressive in the range of wireless speakers.
Design and functionality
The Beoplay M3 is available in black or grey (referred to as natural) color. It’s a 3.2 pounds weight device with rounded sides and measures 4.4×5.5×5.9 inches (WDH). Two 40 watts Class D amplification powers the device; a 3.75 inches woofer and a 0.75 inches tweeter. This makes the device to have a mono output. This is slightly unappealing considering the Beoplay M3 price. Well, we have seen more devices at a similar price with the same mono feature, but there should have been a provision to extend the sound quality to stereo by combining two M3 devices – this is not available.
Behind the device are three buttons; up/down volume controls and a multifunction button. Aside from the buttons, M3 can be controlled using audio commands. Also, there’s a flip at the base of the device, a power button, a micro USB port for charging mobile devices and a 3.5 mm auxiliary input are all available there.

Performance and sound quality
A great feature in the M3 is the provision for many sound profiles aimed at maintaining the quality of sound from the speakers irrespective of where you have places the M3 device. There’s a profile to enhance the quality if you have placed the device on your shelf or hollowed corners. You can also tweak the balance between treble and bass using its touchstone feature – the feature allows you to adjust the balance until you’re satisfied. However, you should always expect the bass in M3 to be more. At least not just one Beoplay M3 review attests that the bass overshadows the treble line no matter how you have adjusted them – mostly when the volume is beyond the middle. The tweeter functions better at the mid and low volumes.
Audio from the device is completely directional. You have to turn the M3 for a perfect sound from the speaker. And you may experience a better sound in a direction different from someone else; this makes it a personal device.
As a device with mono output, Boeplay M3 doesn’t have a great balance to pick sounds from the two channels in stereo outputs. Some tracks like Foo Fighter’s Enough Space sounded empty and localized; the surrounding swirls and whips from the track in a stereo system is completely a miss.
Final verdict
The Beoplay M3 is a portable but powerful speaker with multiple directional supports. M3 has a better sound at mid and low volumes, making it preferable for small rooms. Beoplay M3 price ($299.00) is not bad, being a Google Assistant-enabled device with other great functionalities. It’s a good buy provided you are cool with the mono output.
