Purely subjectively, a metal Pop Filter is better than a nylon one. However, the AUNA microphone, also purchased at MUZIKER.CZ, has a similar metal grille protecting the sensor. So I am not able to assess to what extent it is beneficial for this type of microphone. I also tried it on a desktop noname pole microphone, there the filter's effect was noticeable. + Sufficient filter diameter, neck stiffness - the clamp is only suitable for a standard stand, for other mounting options, e.g. the edge of the table, it does not hold firmly enough.
