I just stumbled upon something surprising i thought i should share. I bought a set of L shape foam from the link below for my MS1's and they transformed the sound, low end was much nicer giving bass drums and bass guitars real power and presence.
Today i received a set of 2nd hand 225i's which came have the L pads as stock, however they sound completely different in that they are lacking in the low end bass i am used to with the MS1's. I was really disappointed in them, and rather confused as i've read from people who have owned both sets of cans that the difference is subtle.
On closer examination i noticed the real Grado L pads from the 225's are constructed of three layers of foam, the middle layer of which being softer than the backing and front section. The ebay versions are a single piece of form, and much firmer. Therefore the real Grado versions are more comfortable to wear.
So out of interest and fairness i took the pads off the MS1's and put them onto the 225i's and repeated the listening test to find they transformed the sound to what i am used to, nice smooth bass notes are back with a sonic signature that is just lovely. ....to me anyway.
I'm very surprised that two similar looking sets of pads can make such a dramatic difference to the sound. I would be very interested to hear somebody else's opinion, if you have €20 to spare please try a set and share your findings..
