Insert the plug for any wired headphones or ear buds directly into the port on the side of the Thinklabs One, as shown in the image to the left, and then turn on the device. Before you insert the ear buds into your ears, adjust the volume (if required) on the One to a medium level to avoid hearing damage or loss.

For users with Bluetooth headphones, Thinklabs One does not offer built-in Bluetooth but does use a Bluetooth transmitter to connect to Bluetooth headphones. For more information on connecting the Bluetooth transmitter to your favorite Bluetooth headphones, click here.
