I am very positively surprised by the good absorption properties of the Walimex Pro Lavalier microphone for Smartphone. The very slight micro is attached with the two enclosed brackets fixed to the shirt or jacket or on the tie, the staples hold very well. The cable is about 1 m long. Then there is the small windscreen on the mic and go recording (there is also a spare clip and a replacement windscreen). So far, I have put the smartphone still before me, partly - has led to really high insufficient recordings - depending on the background noise. By Walimex the micro is close to the mouth, I have an absolutely clean recording. It is certainly no professional equipment for professional audio and film recordings at concerts, but who keeps itself regularly gives lectures, will be very pleased with the Walimex microphone, I recommend it to the full score.
