I know there are several posts about these.. but I have a few questions for those who have had them for a while. 1-How long have you used them? 2-How do they hold up over time? Do they still sound as good as they did when you first got them. 3-How often do you use them? Once a week, several times a week? Daily? 4-How do they handle the low B on a 5? Is it clean? Does it fart at all if your volume is at a reasonable level? 5-How does the cable hold up over time when exposed to sweat and body oils etc? 5-If yours were lost or stolen today wold you get another pair or would you get something else... and if so what would that be? We are on Avioms and I have been using headphones. I really like my ATHM50s .. but I feel kind of silly standing up there with these red headphones on so I am considering getting a set. I have read several reviews and I am trying to make up my mind. I am looking at the 215s and the 315s but I see the low end response is the same.. the 315s just offer a bit more in the upper registers.. The 215s fit my budget more.. So what say you all?
