Bluetooth Speakers With Power Cords

1. Best Overall: Yamaha MusicCast 50 Wireless Speaker

The Yamaha MusicCast 50 is designed as a high-tech multi-room speaker and a great alternative to the superb Sonos Play 5. It’s similar to the smaller MusicCast 20, but it sounds significantly better while offering more flexibility.

Additionally, its low-profile design makes it better-suited for small rooms than most of its rivals. It’s no wonder it’s ranking as the best speaker on our list.

Design & Features

While taking a different approach than most of the newest wireless speakers, the MusicCast 50 is a traditional speaker that supports Amazon Alexa.

However, it’s not a speaker that you can fully control with your voice. That means it will appeal to anyone who isn’t ready for devices without any form of finger operation besides changing the volume.

Unlike most multiroom speakers which tend to be bulbous, the Yamaha MusicCast 50 sits between a soundbar and these large boxes (12cm tall).  As such, you can use it as an oddly shaped soundbar below your TV set.


Sound-wise, the MusicCast 50 tackles most of the audio issues present with the Yamaha MusicCast 20. It offers a slightly richer tone than its predecessor, with smooth and well-textured mids.

The speaker is also a real room-filler thanks to its two large subwoofers sitting at the center and two tweeters angled on the outer side.

The MusicCast 50 struggles a little with bass-led musical genres, but it still delivers natural and crystal clear audio. Additionally, it uses Yamaha’s Music enhancer to boost the sound of poor quality audio recordings, pumping out 70Watts RMS power.

  • Smart, compact design
  • Smooth, well-textured mid-tones
  • Natural, dynamic and crystal-clear sound
  • Dual wired inputs
  • Relatively shallow bass

Verdict: Sporting a modern, oval design, the Yamaha MusicCast 50 is a large speaker that offers sweet-sounding audio in a compact package. You may need to add a MusicCast SUB 100 for improved bass performance, though it can still deliver a room-filling sound on its own. Additionally, you can combine up to 10 MusicCast speakers for multi-room audio listening.
