The battery should last up to 10 hours, and the particularly robust shell should even withstand drops and rain. Thanks to Trueplay, Move automatically adapts the sound to its surroundings. Voice control via Google Assistant and Amazon Alexa is also integrated, but only via WLAN. Also new from Sonos is the "One SL" speaker (200 euros): it replaces the "Play:1" and corresponds to the "One" model, but has no integrated microphones. Another Sonos innovation is the pure electronic component "Port" (450 Euro) for connecting the Sonos system to the hi-fi system. Port replaces the "Sonos Connect", contains no power amplifiers and can be connected to the hi-fi system via analog or S/PDIF coax. Local sources can be integrated into the Sonos radio system via the line input. All 3 Sonos innovations will be launched in September.
