Excellent video. I myself am closet diyer. I had stumbled on the combination of the red nozzle with a #500 filter and a medium density foam did the trick for my EA500. I can actually enjoy them for hours now with no treble fatigue.
I have some iems with interchangeable nozzles but i frankly don´t give to much faith i'm going to notice much of a difference if any, after tinkering with so many and tiny factors to be tested. The time to take them out of ears, pop tips, untwist nozzles, take out inserts, filters grab next nozzles put inserts, filters, tips an finaly plug them to my ear canals must be something in the region of 2 and a half, maybe 3 mintues? And thats for dexterous hands. In that time I don't think my auditory memory will have retained and be able to contrast the details, so don´t think i'll be able to notice much. Good thing we count with reviewers as Mr Tone Deaf Monk to bring some light to it.
Thank you! Wouldn't mind though a vid where you do the process itself, I don't want to damage anything and I'm not sure how exactly take out the metal filter and put it back.
finally got the conch for 13 dollars, thank you for the review, kind of impressive that the conch with the red nozzle graph is as smoth as the ea500 with this mods(with the 8k peak). question: do you think within a year or two base on how the budget market is evolving we will see 1+4 iem for around 50 dollars(decent build quality and tuning)?
