So, I got mugged and long story short I got no headphones, I listen to music quite often so I'm in need of some new headphones, the thing is I only got a budget of $100 no more, I've heard quite a lot of the ATH-M40x and they seem pretty good. I'm a personal Sennheiser fan (already got a headset from them), but I wanna know if any of you got any recommendations, and also I've noticed with my Sennheiser that they rely on an AMP to get some really good sounds, since I'd carry these headphones everywhere I'd like it to not be the case. pls help <3
