A selfie stick has a button on the handle that serves as a remote control to snap the photo with a single click. The stick needs to be connected to your device in order for this to function in real life. There are two options for accomplishing it: Bluetooth or a small cable with a 3.5mm socket. The cost is that, if necessary, the sound cannot be captured. In contrast, the Bluetooth option connects the two for you automatically, with no manual effort on your part. The disadvantage of this function is that it occasionally runs out of battery life, necessitating more frequent charging.
