Because maybe it's a cheaper solution than just buying an entirely new headphone.
I bought the T50rp's in hopes to mod it and get a frequency response chart like the M100's.
I finished my modding, didn't like the results and just pulled the trigger on a new pair of headphones.
I mean more like the fact that the M100s have a pretty well known sound signature. Buying them and then trying to tone the bass down makes me wonder what it was about them that inspired a person to purchase them in the first place, y'know? If I wasn't looking for substantial bass I'm not sure these would have even been on my radar.
