it's time for a new iem and i have limit circa 130$. I read many of reviews and i'm choosing between sennheiser ie60 and hifiman re-400 but i can't find any comparison between them (maybe it's obvious). Or vsonic gr06 seems to be great considering it's price, but is it comparable with ie60 and re400?
I listen to rock-metal, but also classical and accoustic, mostly while traveling (train, bus).
What would you suggest?
