Sennheiser HD 500 : le_kornichon's user review
I had these headphones for a while ... enough to hear that there are bass in there! Trs is beautiful, very comfortable, but apparently for 700 francs (the era ...) I just bought the finish. Sound, it is rotten.
I sold and replaced by an AKG K240m and it's night and day! For 100 euros, it is even more beautiful and more comfortable, and above all it's a TRUE that controls what records and making mix (of course tweak the speakers) and not a "nice" sound that allows just listen to techno or hip-hop.
I'll even when it is 1 / 10 because it's better than the atria.
