The Sony SRS-ZR7 lets you enjoy Hi-Res audio at home, so you won't have to miss a single detail. Use Bluetooth to stream songs from your smartphone in high quality or connect a USB flash drive. If your phone supports NFC, all you have to do is hold it against the speaker to set up a connection. The speaker doesn't stream Spotify from your smartphone, but straight from the Internet. This means you don't have to stay near the speaker, but can roam through your home playing Spotify songs. If the millions of tracks on Spotify aren't enough, you can use WiFi to listen to internet radio. Link several Sony speakers together and control them with the SongPal app.
