V-MODA Vibe duo
I have an iphone 4 and I just purchased the v-moda vibe duo ear buds. They are fine listening to music, but I found that when I tried to answer a phone call, I had crackling in my ear and I could not talk. I pressed down on the mic button and held it and I could talk and hear, I released the mic button and it worked correctly, I could place and answer calls with out pressing the mic button until I unplugged the v-moda from the iphone. The next time I plugged the v-moda back into the iphone, I again had to press the mic button down until I could talk. I don't know if this is a solution or if it just works on my iphone.
