Why does not the microphone to a camcorder or Dictaphone?
If you look closely, discovered the jack (with the name TRRS) a fourth pole, which is responsible for the AUX function on a mobile phone or smartphone.

Why overrides the Lavalier microphone?
A microphone can not actually override, it is always on the recording software and how the input signal is processed. Here either let the automatic free running, which can result in various changes in volume, or to adjust manually, which can cause overloads when the microphone is subjected to a sudden very loud input signals.
How does the microphone on your smartphone?
I have allowed myself the APP Easy Voice Recorder Pro for a few euros in the full version without ads. Here you can a lot of settings to improve the sound. For example, there Codec selection (here one should choose PCM) PCM settings, here you should select at least CD quality, then there is level adjustments, noise reduction and echo cancellation, which can also improve the sound. With the given values I could achieve a very good sound quality.
But Beware:
If the smartphone or tablet is not hardware technically able to absorb as stereo or CD quality, then that is not attributable to the microphone and not the APP. In addition, the microphone can record only a mono signal that can be reproduced on both sides but headphones.
Why not hear the recording?
If you play during recording, you can hear anything, if you do not pull the Lavalie microphone out of the socket. Here said the smartphone or tablet that headphones are connected, and then the sound is not from the speakers.
Sound quality: Because I so own a TRRS TRS adapter plug, I was able to test the microphone on two devices. Zoom H2 and Olympus DM-650th It then shows his quality and I'm very surprised at what comes out of this little microphone. Come on approach almost to the microphones of the DM-650.
Wind noise: The unfortunately there already, even with these small foam pads. Here you should specify a correct Fellwindschutz. The is expensive but really effective. It also eliminates abrasive sounds of clothes.
Contents: One small bag (a little after Nivea Ball smells) two terminals and two foam windscreen.
Conclusion: Those who use the Lavaliermirofon correctly and with the appropriate hardware and software, get really great quality. Those looking for a Lavaliemikrofon for camcorder or other devices that should grab the same to a TRS phone version, which are roughly in the same price range or have even better deals. From King there is this already for a few euros.
