Purchased from e-earphone in late 2023, this is a domestic genuine product. I am selling it due to a system change. The outer box, inner box, instruction manual, and all included accessories are present, and I believe it is in excellent condition with almost no scratches. As the USB C to USB B cable, which is essential for smartphone connection, is not included with the K7, I will include a like-new UGREEN cable as a bonus.
