A:Answer Hello,
Thank you for your inquiry. The Aura S4T model supports multiple input types: HDMI eARC/ARC, Optical (OPT), AUX, Bluetooth, and USB (USB is for flash drives up to 128GB only and cannot be used to connect other devices via USB cable). Please note that this model does not support microphone input and is primarily designed for home theater and audio listening, connecting to TVs, smartphones, and other audio devices. Only one input source can be active at a time, so it cannot play HDMI and AUX simultaneously.
