What i mean by pops is that if you listen really closely while you are talking to someone you can kinda hear a little poping sounds, its kinda like when you turn off your car and you can hear a little small popping sounds. Do not let that discourage you from buying this product. I bought this for my Nex. i870 and it works great. I have yet to have a poblem with it and i have had this for a month. Thank you amazon.
