The Lavalier lapel microphone will be well packaged with a small practical storage bag, and shipped a replacement clothing clip and a reserve Foam Pad (small parts that can easily be lost). I like that in itself very good, as you can take in every super pocket the microphone in it and it has thus always part if you need it once. Since I'm not a technical expert, I can not say much about the technical background and not even compare it with other devices. I can therefore tell only my subjective impression as technically bekloppter user as I am with it came clear. Of course I've read me by other reviews and I want at this point necessarily refer to the review of "bill", entitled "Test and application tips", which was very helpful to me and whose advice I would like to try again, to the micro to give a second chance under optimum conditions. Because I was not particularly enthusiastic about the sound quality, have so far always been a Olypus Dictaphone for my purposes, the significantly better results than leiferte my iPhone in conjunction with the Walimex Pro lavalier microphone. The advice he gives are in my opinion in a manual, which should be accompanied by the microphone so you can use it optimally and achieve good results. Thus, I can not guarantee proper recommendation for the microphone at this point, since I will now give it another try with the advice of other reviewers (eg load the appropriate App - I use the iPhone 5s) but I can recommend the right to inform the purchase based on the good advice of "bill" and then decide what you need. This was not a classic now review and just not necessarily imply a recommendation of the product but rather an indication of review with useful tips, but hope this Notice hift one or the other still somehow in order to gather information.
