Unique Melody MEST MKII Review

For the MEST MKII, UM decided to implement upgraded metal vents for the dynamic driver and the MKII now has an improved sensitivity and response range. “How did UM do that?” you ask?

The UM MEST MKII uses a double sided piezoelectric bone conduction driver. This driver is placed in between 2 supporting plates. At the center of the driver you have the vibration board which is covered by a ceramic coating on both the front and the back. The bone conduction driver now has a larger contacting area with the shells (double sided contact) and as such you feel more of the bine conduction effect.

UM hasn’t touched the rest of the driver configuration compared to the original MEST. There’s a slight change in efficiency and sensitivity, but nothing spectacular.
