I got two of these to replace previous wireless audio speakers. The sound quality is superb, they sound excellent. But after a number of years I'm giving up and replacing these, the wireless streaming is too unreliable.
Support from Bowers & Wilkins has been poor. My units suffer from two problems... 1. They constantly lose their names and revert to a cryptic default. Their support blamed the Apple network protocols, which seems bizarre for a device aimed at the Apple music market. 2. The audio streaming is flawed, and suffers drop outs. Again, their support blamed the Apple protocols, and additionally my network. But other Apple devices work flawlessly with no drop outs.
I'm going to look at other solutions, possibly Sonos.
