Video at Amazon.com view I have the Lavalier microphone, as I received it, immediately connected to my OnePlus One and done at home even in our house a few shots. In addition I have taken the simple sound recorder of the phone and no special software. And I must say positively surprised, it really worked immediately. The microphone has responded to a good way to sounds and record them. Voices were audible without having had to shout. However, the further you removed the microphone from your mouth, the more distant and muffled sound, the voice of those admitted. Since you can attach the microphone but with 1.2m cable close enough to the head and the clip really holds very well, you should always find a proper position for the microphone. Of course, other sounds are recorded, including the Walimex is a simple microphone that works without any additional software. Who would not have noise here, have to go in a silent environment.
What only a little has puzzled me and what I am first stumbled, was the lack of sound output when plugged microphone. Because my phone recognize the microphone as headphones and so turns off the speaker. So if you want to play the recorded, must pull off the microphone.
Otherwise, I think the time is no point to complain, because with proper positioning you get good shots and the price is fine. If I come in the vicinity of a dictating machine in the near future, I will test the microphone even at this. Until then, the Walimex but gets 5 stars from me *****.
