Customer Review

I got myself the KHV because I'm looking for a small and practical amplifier was on. Unfortunately, there are a few problems with the device:

-lautes noise
-schwache gain
-no Improve Audio Quality

Not change the strengths of KHV nothing:

+ Well finished
+ Thick cable

The microphone does what it should and the authority of the iPhone from my 4S in every way.

Unfortunately, the noise floor, along with squeaking loud and annoying, so the device is just an unnecessary extension of the signal chain without more noticeable improvement as "louder than without."
