I've been listening to the Beyer's for a while now, but recently the Philips Fidelio X1 has caught my eye. They were recommended in another thread, and I'm curious to try an open back headphone, because I never have before.
However, $230 is kind of steep. If the sound signature or sound quality is too similar, then I might not go for the upgrade. I'd love to hear any thoughts about the two.
