What customers say about "Key Specs"
Sonos One Voice Controlled Smart Speaker with Amazon Alexa Built In (Black)
  • Small footprint but powerful sound and so easy to use.
  • Sound is warm and powerful so music follows me. I can't imagine to change this. My friends reaction was: wow!
  • I love the sound. I've read reviews that the bass isn't very powerful - not the case. In my kitchen (in loud mode - the default) the bass is fantastic.
  • The sound quality is amazing for a speaker of its size, this is the second SONOS One we have in the house and we have a PLAY:5 in the lounge.
  • Unfortunately, the speakers only have Wireless connectivity - which means the only services you can use are the ones listed in the Sonos app or on their website.
Yamaha MusicCast 20 Alexa compatible Bluetooth speaker with MusicCast
  • It is certainly powerful enough to fill a living room with very good quality sound.
  • Originally had planned to put this in a small loft study but it is powerful. The music quality is better than WX10.
  • Sound quality and power is perfect for a medium sized living room.
  • A powerful, compact speaker with support for audio streaming over both Bluetooth and wi-fi.
  • If you want a simple, compact, powerful Bluetooth speaker, the Yamaha MusicCast 20 is a fine choice.

What customers say about "Size & Weight"
Sonos One Voice Controlled Smart Speaker with Amazon Alexa Built In (Black)
  • The Sonos speakers are very very constructed and would look great in any room. This is the right size and weight.
  • This speaker is great, for a small to medium sized room. They have a surprisingly deep and clear sound, considering they are quite compact.
  • Great sound for such a small body - obviously not Naim level but great! Alexa works all straight forward.
  • The sound puts to shame other devices 3 or 4 times the size. A Small but powerful, weighty product.
  • I don’t like its size because you cannot hide it in a bag and it is small enough to carry it comfortably in your hands.
Yamaha MusicCast 20 Alexa compatible Bluetooth speaker with MusicCast
  • Sound quality is OK for their size, and certainly loud enough for a bedroom.
  • Although the speaker isn't small and is pretty solid in construction, it remains nice & portable and would be suitable if you need to move it from room to room on a regular basis.
  • This Yamaha MusicCast 20 Speaker is a vertical cylinder shape which has a compact footprint making it ideal for the kitchen or bedroom, it looks/feels well made.
  • Beautifully built, heavy and solid it feels and looks exceptionally well built. But the weight is frustrating.
  • The Yamaha MusicCast 20 Wireless speaker is a heavy speaker for its size, weighing in at 4.8 pounds.

What customers say about "Audio"
Sonos One Voice Controlled Smart Speaker with Amazon Alexa Built In (Black)
  • The sound from this is outstanding-once you’ve used Trutuning it fits to the room perfectly, bass is perfect, has way more power than something this size has any right to.
  • Speaker sounds fantastic and Alexa is responsive without having to shout out too loud.
  • It is for me wonderful , easy , responsive , sounds really great and I’m telling all my friends to get one , your worth it.
  • The sound quality from the speaker itself is pretty impressive, although in line with what I would expect for the price. The bass is particularly strong.
  • The only one small issue I have had is that sometimes the voice recognition doesn't work as it should.
Yamaha MusicCast 20 Alexa compatible Bluetooth speaker with MusicCast
  • The audio quality is very good for the size of this unit and proportionately better than some of the bigger wireless speakers in the range.
  • You can tweak Upper, mid and bass frequencies which improve on the default settings delivering a clear, open sound with taut bass.
  • The MusicCast 20 offers rich harmonic output across the frequency spectrum without significant distortion in the upper ranges or loss of sound clarity at the other end.
  • The audio is clean with a particularly impressive bass response given the size of the speaker.
  • The app isn't the most intuitive I've used and I already own Yamaha MusicCast kit - some of the setup routines for logging into streaming services etc. are confusing.
