Bough CAL! 2 locally for a reasonable price. It’s nice looking, solidly build, surprisingly comfortable and lightweight headphone. Pleather pads are comfortable, but not breathable. You will sweat if wearing outside. It comes with detachable cable with microphone, stop/start button and analog volume slider. Nice. The sound. Well, this one’s famous for it’s Foster biodyna drivers. Bass impact is best in class. However, tuning on this model is far from balanced. Think something along the V-Moda M-100 line. Fun, but overwhelming bassy sound. While it can get fatiguing for music in general, for EDM / modern pop the bass performance is fantastic. Really, no other models I heard come near it. It is a big, physical, club-like experience. Higher frequencies are recessed, grainy and somewhat grungy.
When EQ’d it became a solid headphone. Somewhat dark tilt remains, however. Mids stay somewhat recessed. Soundstage gets wider and is solid for a closed back. Solid sound, maybe missing detail a little because of the dark tonal bent. Higher frequencies stay coarse.
It is a specialist headphone, but for its narrow subset it really is incomparable.
