As the others have said, the bar can be used via Bluetooth, WiFi and HDMI. It's perfectly possible to play music from a mobile phone via Bluetooth. With Wi-Fi, the advantage is that you can use the speaker in Spotify without a permanent connection between the mobile phone and the speaker (remote play). On the other hand, I wouldn't recommend a Wi-Fi connection between the television and the speaker, as I often get a discrepancy between the picture and the sound.
