I'm getting a pair of free Beats Solo HD. I am selling them even before I'm getting them, and I'll probably get around 180 € for them. Instead, I want to buy a pair of audiophile headphones, something the range of Grado SR125i's, I was looking at Alessandro MS-1i. Are there any other headphones I should consider? I want a nice, realistic sound with a good soundstage, pricing up to 150 €.
I listen to mostly rock music, but also other genres. I am a semi-professional musician, so SQ is crucial to me. So my need is something in the sense of UE Triple.fi 10 Pro in-ears, but the headphone version. So as flat EQ as possible.
