Yeah np. Need to remember again im not professional and i have probably some hear damage(not 100% like when i was young). I listen a lot of music, so this was definitely leaved some consequences. I'm also not basshead.
To me default fostex provide good smooth sound, but something was not right to me as mids were way back for me and not involving, to shy. Highs were prevealed although great. Also lows had that bump around 100hz. To my ears and perception it was like lows "eating" lower half of mids spectrum and highs "eating" upper half
In whole, the sound was, although laid back, to dense to me with everything but no mids. Like sound was compressed and had not enough room to "breath" to full potential. I'm bit exaggerating here, but phone on default had that tendency to leave that impression to me. It was time for modding.
- I was ordered Hybrids and puting in on. It was just a few seconds i was know, this will no go for me, as the low and high end preveale even more
- Then i open the cups and first remove that black tape from vent(first picture). Consequence was, LF were lose some energy, but sound become somehow more light and a bit more open which i like.
- Next, i'm thinking about reducing that bouncing sound waves in plastic cups, so i put in that low dense, grey piece of foam and with that, cover the vents. Also in inner side around cup(this is where is bad lows building up, when the cup and cover are sealed) i placed sealing strips that is normally using for windows(1.,2.,3. picture).This all obviously clean the sound of some muddines.
I was listening then so a few days but still, i was not quite pleased. Then i was start to thinking about that quite dense foam with rectangle cut in front of driver. I was somehow sure this have great impact on sounda as the foam is quite dense and leave qiute a small room for sound to evolve, This sure must have hurt mids the most i was thinking.
- So i was take down original one and replaced it with round pice(withou rectangle cut), cuted from the same foam(5.,6.,7. picture), i use in back of cups. I was right, the sound become more calm down and even in spectrum, more airy because of new foam which were not so dense, so sound is not building up and "pumping" in that area, Sound spikes were reduced also. There is one negative impact. Ofcourse, because we cover the driver with foam, sound become a bit muffled, wich cause that highs lose some details, but nothing drastic and i can happily live with that as cans are so or so very detailed sounding.
With all easy mods i've done, the cans are more pleasant to listen, at least to me. But i'm sure there are people, which will say, "what are you thinking?" on a bad way
That's perfectly fine.
