The device needs to be within a reasonable range in order to connect.

  • In general, to pair and use a Bluetooth device (like a speaker, headset or smartwatch), the device needs to be within 10 feet of your computer or other device.
  • Some medium and higher-power devices can be farther, up to about 30 feet, but this tends to be for larger devices that plug in or have very large batteries, such as another computer, media streaming device, or a plug-in speaker system.
