Endura ESM-20-HY1L Speaker Mic for HYT Hytera PD502 562 TC700 BD502 and Titan TR Series Two Way Radios (See Description for Complete Radio Compatibility List)

I've had this for a few weeks now and I just can't stand to use it anymore. The speaker makes a loud pop every time it makes a sound(receiving a transmission, or pushing a button on the key pad). It doesn't matter if you turn the volume down, the pop stays just as loud. And since it sits closer to your ear than the radio, it's very annoying.

Performs as expected, clear and crisp
