The bass does get toned down a bit compared to M15, however it doesn't bother me much since I think M15 still has too much bass boost. (M20/M15 is fun at first when all the bass region is emphasized but for me it...- Lerrens

Thanks for trying this out and sharing the process, I assume I would also be do the same thing when mine arrives.

Drop + Ultrasone Signature X Headphones Discussion

Mathematically speaking, the 'ideal' anti-aliasing filter (a filter that removes all frequency components above a certain frequency, without affecting lower frequencies at all) would in fact be a...- Lerrens
