Good device, but only partially for mobile use

I have mixed feelings on the device, and it can Tascam nothing pure.
The part is solid and works implemented both hardware and software side without any problems. One need not even the Tascam software once it is infected you can use app with the previous favorite Recording. Only listening through headphones requires after connecting the Tascam iM2 re-plugging in the headphones damits works.

My concerns do not refer to the device itself - is the quality of the recordings quite well (naturally much better than the standard iPhone microphone) - but on the question of whether so makes a Ansteckmikro se sense. Any movement on the iPhone, each tap anyway, recording bothers immensely. What has surprised me: also moving (winds) leads to violent background noise (crackling). Therefore, you can not really use the mobile part, but only to hold discussions / concerts / JamSessions / meetings, if you can lie down somewhere untouched. There is certainly great.
