Query: It works sound isn't very clear

a friend of mine has this exact same mic, his sounds crystal clear, the one I just received tends to pop when saying any words with a P or a B, if I use this for voice calls I'm sure the person on the other end would be extremey annoyed with the loud popping on certain words, seeing as my friend's mic works perfect leads me to believe mine is just defective,, I purchased a used item to save a few dollars, turns out that was a bad move on my part, I'm not gonna bother returning it since it was inexpensive and it would cost me 2/3rds the price of the microphone to send it back, sending it back wouldnt be worth the trouble, lesson learned no more used items from amazon
