You need an app to listen to radio D-TWO on your mobile device, because the player on a webpage like this one, will stop playing as soon as your device is in stand-by. You can use the Online Radio Box app (android or ios), or the radio.net app (available for ALL devices).
Install the app, search for D-TWO and press play. Or use one of the standard Media Players listed below.
If you have one of these Media Players installed on your device (mobile or not)
you can simple listen to D-TWO by clicking on the according link below.
VLC MediaPlayer - iTunes - Windows Media Player - Winamp - Open format
On PC: choose open with and select your player by clicking 'other' if it's not the default player that shows up.
If you have trouble getting D-ONE on Sonos, maybe this guideline may help
