If durability is your number one priority look no further. I've washed these by accident twice and they were in the drier once and work perfectly. The first time I washed these without drying, I used them when they were wet, the sound was messed up from the water in the driver, but when they dried they were 100 percent back to normal. The cabling is really, really sturdy, they don't tangle much and they are metal.
When I first got these I felt the high end was harsh and over emphasized. I've gotten used to these over time. I love them now. Its not that I am trying to love them, but I actually love them. I got used to the high end. The mids are super super smooth and clear and organic sounding. The bass is powerful and present without sounding bloated. Its really well controlled and its smooth but not punchy or fast. Yet I think it will satisfy most people. These manage to be somewhere between fun and nuetral. The high end once your adjusted to it, actually makes music more insatiable and more fun. Its not super super over emphasized or siblant, but when you first get these if your used to a darker sound, everything sounds kind of veiled by the high end. Everything sparkles. I would describe these as bright, but the mids and the low end is equally there. Its just the sparkle of the high end sticks out most on first impression. Over time, the sound seems to make sense. I mean I really do like these and after comparing them to some full sized cans, IMO these sound better. In fact, I am currently looking for full-sized cans that have a similar sound.
I just think these are hard to go wrong with if your someone who leans more towards a balanced sound but want something with great soundstage.
I first started using these with an iphone 5 and then switched to an iphone 7 and I definitely noticed a difference in quality. I don't amp them...but source does matter with these. They sounded much smoother on the iphone 7 and a bit more "tame".
