I just purchased this mic and am using it with my iPhone 4 with the adapter. Trying to shoot a video with iPhone. I inserted the battery according to diagram, but volume on mike is very low. I do have the switch to on. How do I increase the volume?
I am having the same issue, and my experience is exactly the same as the responder who could blow across the microphone and hear the wind noise, but there was very low voice output. I am connecting the ATR3350 to a Behringer amplified speaker, and the 3350 should have many times the needed drive, because a dynamic microphone connected to the Behringer has tons of output.
The best part: connecting to the Behringer's "CD Input" RCA jacks from a 3.5mm TRS-to-2xRCA splitter, the voice output sounds normal, although the level is down (the CD input sensitivity is 30 dB worse than the Mic input in the Behringer), so the CD input seems to be working properly. Not sure what to think of these inconsistent results.
