Thanks for your input Craigster75! I am leaning towards the Signature Pros at this point as I think they may offer the more neutral (and "tamer bass") sound that is suitable for applications in radio production, while still being able to satisfy me musically.
However, I do love my EDM and I hear that type of music works extremely well on the Signature DJ. Tough choice ahead.
So true. As a content Sig DJ owner, I will go as far as to say there isn't another headphone made at any price that sounds as good with EDM as the Sig DJ.
