Question for those who already have this headphone. I just received mine about an hour ago and while I realize they need to be broken in for up to 200 hours, they sound very bright and somewhat weak on bass. How much change can I expect once broken in? I have yet to try any of the dampening pads and figure I'll wait till the stock headphones are fully broken in. My other headphones are Sennheiser HD 660 S which sound completely different and definitely warmer.

I have the original AFC and the HD 58x so probably a similar basis for comparison. The Aeons were brighter out of the box although I wouldn't say in a bad way. I ran them with the standard one-notch white filter for several months until I thought they started to sound slightly veiled and then moved down to the black foam. Try the filters and tune it to your ear. That's why they're included.
