I personally find these to be pretty amazing. But im not to sure who they are made for. These are definitely sit back and relax headphones. They benefit greatly by being connected to an amp. But these falter hard in portability.
So first the sound. It has amazing sound. The highs are pretty strong with a decent bass. You can feel the separation of the 2 drivers and their size is definitely to your benefit. But the mids feel a bit lacking. Because of this, you will often find yourself bumping up the volume and then being assaulted by what is honestly crisp if maybe a bit harsh highs. However, you simply are never going to find and IEM, if you can call it that, that is this open with a decently wide sound stage.
Then we come back to whats not really good about the headphones. They lack any real semblance of portability. While the case that comes with it is pretty amazing, its a bit bulky, as are the headphones themselves. There is absolutely no isolation with these headphones so wearing them on a plane or train is not going to be a fun time. And because you have to have the headphones on just right to get the good sound, wearing these while exercising or even doing chores is pretty bad as they will move or fall out. And if you are constantly adjusting them, the hard plastic can really rub your ears the wrong way.
In short, these are meant to be something you keep at your desk. That you pull out and have a relaxing listen to in a quiet room. They can also be good in an office environment since they leak very little noise despite being very open, and otherwise dont stand out to sharply. And they arent to bad for gaming either.
