Good sound, especially for its size. Easy to set up and works well as part of a multiroom system

I bought two of these to provide stereo in a study as part of moving towards a multi-room audio system. Already had a Sony SRS-HG1 speaker in the kitchen which I liked and the 2 x ZR5s integrated seamlessly into my Google Cast system. A deeper sound than the HG1, smart minimalist look, linked easily to produce stereo, and have a decent range of connections to link in different ways. SongPal app that configures the speakers is problematic, and needs the Google Home app to group the speakers together for multi-room functionality, but so far I'm impressed. Sony back on form again

I bought my Sony SRS-ZR5 as a standalone bluetooth speaker to use with my Echo Dot. I wanted a speaker that would sound better than the Echo but, since I already own a Bose Soundlink Mini, portability was not something I needed. I looked at several speakers but none had such a wide range of features and connectivity. The speaker is always on, although if I switch it to 'Network Standby' mode a voice command to the Echo Dot will turn it on and reconnect it. The sound is excellent; It is clear, sharp and warm. Having read several reviews I was not disappointed. I use the speaker to listen to voice and music radio, Amazon Prime Music, and to cast my own music with Google Chromecast - it has replaced an ageing DAB/CD stereo. Set up was clunky with the SongPal app and I actually used the WPS function on the router in the end (the app could not complete set up and I gave up "trying again"). I have had cause to set it up again (router problem, not speaker) and used the NFC function with my Android smartphone, which worked flawlessly. The app is probably the weakest link in the system at the moment. I am delighted with the Sony SRS-ZR5. It fulfills the role for which it was purchased perfectly, and in combination with the Echo Dot has replaced the audio equpment I was using. It has a wealth of connectivity options, sounds fantastic and appears to be fairly future-proof. I intend to purchase another ZR5 in the near future for the stereo pairing capability, and may at that point connect the system to my television also via the HDMI.
