Before my MP 8320 died from that terrible tangled cord, I felt they sounded very similar to the SHE 3580, altho' I didn't think either had a V shaped sound. Both have very good mids to me, in good balance with bass & highs. But I do think the MP gets a slight nod in the details level. I would order another MP if I knew they had a better cable, and a smaller housing -- it was kind of ridiculous! But with the SHE 3580, I haven't missed the MP 8320.
