A:Answer I had same issue when using with my Samsung Galaxy S3.
Did you see the tips in the manual?
• Clip mic upside down (prevent breathing noises)
• Put as close to audio source as possible
Even when I did this...I still had static/ambient cracking noise
• There was a comment in manual on Page 7 about taping wire to inside of shirt: "Tape a loose loop of the microphone cord to inside of your clothing. This provides additional strain relief for the microphone cord AND ISOLATION FROM UNWANTED NOISE."
After about 20m+ of testing...turning off fans in the room, etc. Holding mic to mouth, clipping it etc...I finally just ran wire under my shirt and clipped it. It removed a ridiculous amount of the ambient/cracking/static I was previously experiencing. I was about to return this thing. Didn't think that would make that much difference...but I guess it makes sense...that entire wire is transmitting the audio signal.
