depending on the pop filter and what its made from, it can also round off the highs nicely. 

I've used one on a dynamic.... and now that I use a condenser.....I use the pop filter most of the time.... on occasion I have actually recorded without one.... you got to be very aware of the coming words and be ready to compensate with vocal technique to pull that off successfully. 

the metal ones really work well.

Lol, good point! I have a dual fabric one. I'd like to get a metal one in the future, but my mesh does the job for now.

yeah, but these are usually amateurs 

I have one of those styled pop filters for a SDC mic. I've never tried it on vocals before. What is an incredibly sibilancy/popy sentence I can use to test it with and without the pop filter?

So what is that sentence?

Sentence?... Nah!! For best results use about three words for example; Sh#T + Puffy + Shoes  --- repeated fairly abruptly over and over with about one second intervals  

@ OP

   I think Dave summed it up quite eloquently:  
 
It's much more critical on condensers just because they are so much more sensitive. Dynamics are inherently more immune to pops and sibilance, and they usually have some kind of integrated pop filter built in to them. People often use dynamic mics because they can be hand-held, which many singers are more comfortable with. Obviously, a pop filter is impractical if the singer is dancing around. 


   Especially in this last part; 

But that doesn't mean a pop filter wouldn't be beneficial if it's on a stand, especially for a singer that works the mic as if he were inflating a balloon. 


    

Pop filters should always be used for singers. Unless they are singing "Pop music?" In which case, you might not hear anything...

(I'm sorry for that right there Lord.)
