While I've been mostly impressed with Sonos over the years the response from CS to my recent enquiry with them REALLY beggars belief!
I recently noticed that my Bridge has died and found on testing that it was the power supply unit (a problem which seems to be more common than you'd expect). So, needing to replace it, and not being in a country from which it's easy to order direct from Sonos, I asked CS to tell me the size of the connecter that gets inserted into the bridge. 2.5mm, 3.5mm or what?
The response from Sonos CS "I believe that is is 2.5mm but I cannot say for sure. However, you can also purchase a replacement BRIDGE cable at https://www.sonos.com/shop."
Can't say for sure? Seriously? Didn't Sonos design, and doesn't it sell them? Gotta be one of the poorest CS responses I've ever had!
