NXG Professional 4-Channel Mixing Console This is a mixer for connecting microphones and instruments. It can directly play songs stored on a USB memory stick, and also play music via Bluetooth. I have used it about 5 times, but I am selling it because I have no plans to use it in the future. I performed a usage test on January 10, 2026, and found no issues. (Please understand that I am not using it for work, so I only found no issues at a novice level.) During the test, I connected a microphone, a computer, and an iPhone (Bluetooth) and outputted the sound to speakers. As shown in the third image, the base of the cable is slightly visible, but I contacted the seller, and it seems to be a specification of this product.
