I bought this with the intent of using it to listen to car noises. The construction is flimsy, the volume knob is very noisy on both units (turn it and sound will go out, nonlinear volume control, sensitive to just touching it), the headphones are very VERY poor quality and even when working the mic and amp is marginal at best. I disassembled one unit, and the amp is just 3 transistors versus an IC amp in other units.
These are very very poor units - spend more on a different brand.
