All speakers needs a source to play from. None of Senitrus computers, nor handhelds has an audio port. With that said, the speakers must connect via USB-C. This will be simple enough to support the entertainment or productivity of the user. The goal of using USB-C only is to eliminate legacy ports, and devices by only support for proper standards. USB4 does not support USB-A, or USB-B as connection options. Since USB-C is the proper standard, only USB-C will be used. And since USB-C can Carry digital audio, it just makes to use USB-C instead of 3.5mm audio. This means one less port to confuse a new user with.
