This is the fist time I upgraded a headphone, I did some repair work on some cheap headphones which I burned the driver, so cutting the wires on a perfectly working headphones with barely a hunded hours on them was a bit scary. I kept saying to myself its only 3700 pesos, its only 3700 pesos as I cut the wires from the driver, after that there was no turning back as I go to the bathroom to change my underwear.
I can not comment on the sound as I use the HP at the office and brought it home for the upgrade. I tested the HP on my kids player and the HP is easier to use as its no longer has 4 feet of extra cabling and the cable is a wee bit stiffer than the older one so its less likely to get tangled, that in itself is worth the cost/risk of the upgrade and if the SQ improves thats just icing on the cake.

I added this info October 12
Listening Impression after three hours.
What I noticed immediately was the mid bass response, the sound was thicker. I reckon the resolution was a bit higher as I could hear some high frequency detail that I could not hear before. Not sure if this frequency band was enhanced or that the mid bass was cleaner allowing these details to be heard.
