With the popularity of wireless music playback, it's no surprise that many soundbars now offer this feature. With the built-in Bluetooth feature, you can easily stream music from your smartphone, tablet or Bluetooth-enabled computer. Almost all soundbars today work flawlessly with your favorite music streaming apps (Spotify, Apple Music, etc.) as well as music stored on your phone.
Some soundbars also come with Wi-Fi capability for quick access to online streaming services as well as your personal digital music library. Soundbars with this feature include Wi-Fi-based wireless sound systems such as Play-Fi, which lets you set up a multi-room audio system for seamless music playback.
Many soundbars also have a USB port. So you can load your favorite songs onto a flash drive, leave them plugged in above your soundbar and listen to them whenever you want.
