see the specs on the M50x are actually better, and it is cheaper.
Until headphone manufacturers actually advertise what drivers they are using and who makes them... i have a hard time paying too much for them.
I think the m50x at $150 is a good buy. More than that though and idk, i just have a hard time. The read was very anecdotal, but nice and something people should consider.
I'd like to see them do some pink noise attenuation and various physical, repeatable tests on some of these high end sets.
I just don't believe that one 40mm driver made in a factory in china is amazing in a high end set, but that same 40mm driver could be found in dozens of other no name brand sets.
I just don't trust it. we need more breakdowns of these things to see what the consumer is actually getting.
