I bought 1 Sonos S5 and 3 Sonos 3 a few years ago.
it cost me some amount of money thinking that I had a system that could last for a certain time.
then Sonos developed S2 which is not compatible with the previous generation. This forces the customer to let down their previous equipment and change the whole system.
This is and stupid scheme
of planned obsolescence which not acceptable with current sustainable policies and for this reason, I DO NOT RECOMMEND TO ANYONE TO BUY SONOS EQUIPMENT ANYMORE UNLESS THEY CHANGE THEIR POLICY AND FIND A WAY TO MAKE THEIR 1st gen system compatible with the S2 App.
Next time I buy a music equipment I’ll avoid SONOS.
What a disappointment !!!
