On the inside of the iem, there are “TFZ-IEM” and model number printed in gold. The nozzle is slightly angled with metal mesh. The Secret Garden HD utilizes 0.78mm 2 pins connectors.

The connectors have a transparent housing. There is a memory wire area and the cable is enclosed in a transparent heat-shrink tube which is very flexible.

On the housing of the jack, there is the brand logo printed. There is a smooth surface to the jack housing. Overall, the cable is flexible with little microphonics.
