My head is going now wild. I have been waiting this headphone to mod. I see already it has some flaws on construction side but I don't mind really. It may be ugly duckling that just need some care. I love only cheap headphones that can produce bretty good sound after modding and equalizing. I'm only owning one planar magnetic hp, that is echo tds-16 and I must its very difficult to mod. Dynamic drivers are much easier to work with it.
