Don’t know if I’m late for this but remember to clean your cable terminals (2 pins and plugs). I was asking dunu about rewiring or resoldering a cable I own from them (lyre 2 pins) since it’s my favorite cable, the sound wasn’t crisp anymore and I was super annoyed cause I could tell by switching cables that the sound was muffled. Today while taking out my cable i thought about cleaning the terminals... maaaaaaaaan, sound is back and present, the aten cable is amazing but I love to just switch terminations and keep with my headphones on while on home (I use 2.5 for my hilidac to walk out the dogs, 3.5 for my ps4, 4.4 for my wm1a or hiby r6pro and so on) just clean the terminals with rubbing alcohol and let them spark again, as well I did a through cleaning to my r1z, the piezo piece was full of dust, they are my everyday headphones so i was expecting some grim, no ear wax, just dust, I clean em up with a qtip and some rubbing alcohol; for a couple of days they were a bit harsh on the treble (I actually mailed bob, he asked me to burn them in for a couple of days) they are back to normal and well, it’s just something I think I should schedule to do. Out of all
My collection, my imr’s are my most used iems, it sound signature is my preferred and the ability to switch filters just makes the whole experience better for me since I love tweaking stuff. Just my 2cents
