What is AUX?

AUX, also known as auxiliary input or an auxiliary jack (headphone jack), is a point of connection that’s commonly used in audio devices such as MP3 players, microphones, speakers, headphones, and soundbars. You can connect two devices using an AUX cable in an asynchronous way. This means that it transmits or receives data one bit at a time.

As many devices have AUX ports, you should have no issue connecting your soundbar to a wide range of devices, including your TV. All you need to have is an AUX cable. And this is one of the advantages of using AUX.

Another good thing about AUX is that it has a simple and easy playback with minimal compatibility problems that may plague digital connections. And if you don’t want to do all those complicated procedures in connecting your soundbar to a TV, AUX is definitely a good choice. You can easily and quickly set it up in less than 5 minutes.

However, there are also some drawbacks to using the AUX input. One, these cords are typically flimsier compared to other types of cords. They also wear faster because of the small surface area on the metal jacks.

An AUX cable is a common option among old-school soundbar owners. The quality of sound is definitely better than when you are listening directly to your TV audio. However, it’s important to remember that with AUX cable, it offers an analog connection so the quality of sound might not be as clean as when you use optical cable or HDMI.
