I'd like some help from the experts please
Music: Dubstep, bass heavy. Drum and bass sometimes.
Use: Outdoors commuting, hooked up to my iphone 5 (guess I need low impedance). I do not want a portable AMP.
Design: Prefer industrial design sort of like the Custom One Pro's
Essentially I love the look of the Custom One Pro's and reviews seem decent enough. Are there any alternatives for quality bass so powerful it may induce the defecation of one's liver?
