I know some folks will be turned off by the high price of just one foam filter, but there is a big difference in quality between this one and perhaps cheaper brands. First this is actually going to fit on an SM58, unlike the $1.00 filter I bought at.... which tore as I tried putting it on my mic. Second, the cheap windscreen , did not cut the pops as well as a real Shure. Third and most importantly, it is more acoustically transparent, meaning less loss of high end frequencies than the inexpensive brand. Price does matter in this case.
