Bluetooth is a short-range wireless technology that allows you to connect headphones or portable speakers, a stereo system or a soundbar to your smartphone or laptop. For a certain version to work, both devices must support it. The versions differ in data transfer speed, power consumption, securing data transfer, anti-interference ability and range of connection.
The length should allow you to lay the cable with a small margin. The longer the cable, the more impact it can have on the sound.
