I think planar magnetic headphones and the more common dynamic-type driver headphones have advantages and disadvantages over each other. There really is no winner, in my opinion, they are just different from one an other. However, personally i've always preferred dynamic-type driver headphones because I find they sound more natural than planar magnetic headphones, I put it down to the shape and function of dynamic type drivers ie the way the sound is dispersed/projected in an circular motion, in comparison, planar magnetic drivers are a square/rectangular shape, which is an unnatural shape, and the sound is dispersed/projected uniformly, which does explain why planar magnetic headphones tend to sound very flat. I haven't owned a planar magnetic headphone in 5 years but recently decided to give planar magnetics another chance to impress me, and i'm hoping the Acoustic Research AR-H1 will do just that.
