I've read on solderdude reviews that thin or thicker felt or even toilet paper fixes some FR problems on some headphones which have a spike on FR. If this could be fixed so easily, why do the manufacturers prefer not to fix it? A good example is AKG k612 pro.
Or a simple filter can fix a lot in frequency response but manufacturer doesn't to that.
Why do you think that manufacturer aims to make frequency response which is not flat and not better sounding for many people?

I've read on solderdude reviews that thin or thicker felt or even toilet paper fixes some FR problems on some headphones which have a spike on FR. If this could be fixed so easily, why do the manufacturers prefer not to fix it? A good example is AKG k612 pro. Some do and have damping materials in front of the driver. It kind of kills 'sparkle' too which many people like. Look at the efforts Beyerdynamic makes with the DT900 and DT700, Amiron Wireless and some new models that don't have the typical Beyer peak because they now have a thick layer of damping materials in front of it. Look at the HD681EVO which got a thick piece of woolfelt on it removing the piercing treble of the HD681. Or a simple filter can fix a lot in frequency response but manufacturer doesn't to that. It is expensive... Hifiman used my filter (I designed for the HE350) in their successor the HE35X. The Audeze sine has a filter circuit. The K1000 has a filter circuit in it as well. Why do you think that manufacturer aims to make frequency response which is not flat and not better sounding for many people? A: It is nearly impossible to make a flat headphone. B: Completely flat (as in equal SPL at each frequency) is not liked universally. Research has shown elevated bass, subdued upper mids and elevated treble (to add sparkle) is preferred by the majority of people. That's who they have to sell their merchandise to.
