The Riva Arena is a great-sounding alternative to Sonos for Android users who want to roll their own multi-room speaker setup.
iOS users have little reason to get the Riva over the comparable Sonos, however, since AirPlay currently doesn’t support multi-room audio.
However, for those who don’t like how Sonos speakers sound or simply don’t want to buy into the Sonos ecosystem, there hasn't always been a ton of stellar alternatives.
Samsung and LG have their own multi-room speakers, sure, but they can be quite expensive and some don’t sound particularly great.
For those who want the convenience of a multi-room setup, the $249 (£225, AU$369) Riva Arena is an excellent Google Cast-enabled alternative to the Sonos Play:1.
The RIVA Arena looks strikingly similar to the Sonos Play:1 with its rectangular shape that will blend in well with the rest of your audio equipment.
