What is Audi A4's Option Code 6NQ?

I'm looking to purchase an Audi A4 and noticed the option code 6NQ. What does it stand for and is it worth getting?

Option Code 6NQ is the Audi Phone box. It is a wireless charging and signal booster feature for your phone. While it can come in handy for long drives or if you constantly need to use your phone, it is not a necessary feature. Instead, just invest in a good phone charger and hands-free device for a more cost-effective option.

The code 6NQ stands for the Bang & Olufsen Premium 3D Sound System, which includes 19 speakers and a 16-channel amplifier. This top-of-the-line audio system provides an immersive sound experience for both driver and passengers. If you are an audiophile or value high-quality sound, then this option is definitely worth considering.
