With the Bang & Olufsen Beoplay M3 you listen to your favorite music in high quality. This multiroom speaker contains 1 woofer and 1 tweeter. Because of this, both the high and low tones sound powerful and you hear every sound detail. You connect the first with mains power and then via Bluetooth or with your wifi network with your smartphone or tablet. So you stream music from your phone or tablet to the speaker. You can access streaming services like Spotify and Deezer thanks to the built-in Chromecast. This also connects other Chromecast speakers wirelessly, so that you create a multiroom system. You operate the speaker easily with the physical buttons on the device. These are neatly concealed in the sleekly designed housing.
