Pros: Indestructible build, good "musical" sound quality, good soundstage
Cons: Huge bass boost, cable could be more flexible, no neck cable adjuster, wide nozzle, shallow fit only, weird over-the-ear fit
These are budget-minded basshead's dream come true. Others might not be satisfied by the bottom-slanted sound, which can be hugely improved with equalization, otherwise they sound dark and laid back. The sound is precise, with engaging musical quality to it. Bass is very well controlled despite the amount. Mids are neither forward nor laid back, perhaps slightly boosted in upper registers. Highs are actually well extended, but overshadowed by the huge bass.
Brainwavz M2 are very efficient and despite it, don't hiss at all. However, they will pick all stray mains hum.
