You guys talk so much aobut the Koss Porta Pro that I'm trying to hold myself on not buy them. I near a low tax area of Paraguay and they are about $40 to $46, maybe I'll buy one...
Anyway tomorrow if I'm lucky I'll visit one of the few hi-fi stores in South America, they have stuff like Audeze's LCD, a Focal Clear and more, will be the first time hearing those big boys, if I'm sucesful I'll give some feedback and try to compare them with the 58X.
Edit:
My uncle tested the 58X, he loves and knows a lot about music so he had some great albums to test the headphone, he really likes the 58X, tried both with EQ and without, he tought the 58X with EQ was better as well except in some songs like Take Five where cymbals were a tad too metallic.
I like how he doesn't know much about the headphone world but described the sound as having some slight "velvet" feeling.
This is one of the songs he used to test, from the co-found of the Beach Boys, it's interesting.
