Mohannad13Yes, better by far. They are musical and totally engaging. First listen reminded me of my first time with the Etymotics ER4s - realism, inner detail, recording space, and tonal quality are amazing. I don’t use equalization per se, but I do make use of a response correction curve via a plugin called Morphit. The plugin does’t have the Koss info, so the correction curve I use is for the Stax SR207. The Stax has a very similar frequency response curve.
Funny thing with me is that I use the Koss (and Ety’s too) only when I want that musical immersion using the highest definition music I can find. For lively listening, it’s usually the Grados. For detailed closed-back, it’s the AT MH50x. I occasionally use the HE4XX’s, but not much. Also, I’m trying to like the 6xx. They seem a bit less musical (restrained?) but I may just need a more appropriate amp for their load.
aleph0Sidenote: update - tried the 6xx with a BlasterX G5 dac/amp. Opened up the sound significantly. They're maybe still not quite at the musical level of the Koss or Ety's, but then again, maybe they are. At any event, now I will add the 6xx's to my listening set. I will get more time with them on different types of music. It was definitely the lack of sufficient amp to drive the 6xx's (had been using a Dragonfly Red).
