I've been looking into buying new closed cans now, but apparently the signature I'm looking for only comes from open cans. Only things I found that can compete is a Mad Dog or Shure SRH1540. Mad Dog needing a powerful amp and dac, both are ~600. My budget is ~300, I can increase the price to ~400 but would prefer not to (unless the upgrade really is worth it). So how does a mic work with open cans? Is it a possible concept? I currently have the V-Moda's cable mic that I can attach to any headphones with a detachable cable.
