Hi guys. So I am heavily considering getting these headphones. There's a very nice hi-end audio store downtown here that has them on sale for the same price you can find them for on Amazon and such. I have a few concerns though. I've noticed in many reveiws that people have issues with one or the other of the drivers on these failing after some time, or in some cases after almost no time at all. I myself have had this issue with some supposedly "nice" headphones before. . .even a pair of Momentum On-Ears which have a power-rating of 200mW, but in which the right driver blew out after only two hours using them new out of the box! So, I am very very concerned about all the reports of this ocurring, as well as the fact that the M4U1 apparently have a power-rating of only 30 measly milliwatts! Why were these headphoens made with such an incredibly low power-handling rating, and should I be concerned about getting them for that reason? Keep in mind that in the stoer where I tried them out I had the chance to listen to: The Sony MDR-1A, the M4U1, and Sennheiser Momentum Over-Ears. I thought that the Sony MDR-1A sound about as good (a bit warmer though) than my current headphones, a pair of V-Moda M-80s, but with better isolation and a bit better detail, or so I thought I could hear, and a better soundstage overall. The Momentums sounded super-duper unremarkable, I was disappointed with them. But then, the M4U1 BLEW ME AWAY, those things sound SUBLIME. I really want to be able to get them! But I am concerned. . .their power-rating is only 30mW, while the Sony MDR-1A are rated for 1500mW! Am I likely to blow out the drivers if I am driving them from a Fiio X3 2nd Gen DAP, and if so, would they not be worth getting?
