new stanton n 500 needles are collecting dust

I've  bought   the staton n500's needles for my turntables.
Ive had always the stanton d5100al-II but the seller told that they didn't make them. Now I like this n500 needle  its sounds a  lot "warmer" but they just collect so many dust. Its not normal.
has anybody the same problem ? I ve never had that problem with the "old" d5100 al-II needles.

this is the n500's

this is the stanton d5100al-II
