With the Sony SRS-ZR5 speaker you play music in a variety of ways. Connect a USB stick, stream wireless numbers from your smartphone via Bluetooth or switch on Spotify and Google Cast. Thanks to Spotify Connect you have access to a range of songs that you stream directly from the servers. So you have no limited range like with Bluetooth. Through Google Cast you listen to podcasts, thousands of online radio stations and music from your laptop. Connect multiple Sony speakers and create a multiroom system. Place the speakers in multiple rooms and operate them with the SongPal app. You can control the speaker wirelessly, but you do need to be connected wired to the mains power.
