It works with the supplied plug only on iPhone or Android smartphones. For a few euros but you can buy an adapter and then you can it to laptops, cameras etc. use.
Best the right app for Smartphone you will download itself, then the application is easy.
If you have securely fastened it with the clip you get a clear recording, but you move too much and it slips a little on clothes you can hear these sounds also.
It is relatively small and thus not conspicuous. One can therefore important conversations well record, so you can listen to it again later in order for example to take notes.
The recording quality is good, there is hardly any noise. Outdoors and in windy conditions one notices but a nuisance. I think it's more designed for indoor use.
All in all you get with the Walimex Pro Lavalier Microphone a small practical helper for little money. Those looking for a little and everything good microphone for his iPhone or Smartphone is served here well. Who needs more professionalism must buy a more expensive mic.
There is nothing to complain about, the price and performance vote.
