Okay so my initial impression of this mod is that it sounds good. I love the 'open' sound they produce now. Also, I still have to turn down the bass frequencies, or it's very boomy, not thight. I've mostly only listened to classical music so far with them, so I don't know how they sound in other categories. They might be unstable for all I know. I wished that I could describe the sound more in detail, but I'm not really qualified for that. Note: This is just my personal opinion (so far), You may, or may not, like the difference in sound produced if you did this risky mod yourself. If anyone wants to try this mod, I might be able to help you out. I sure did some quite nasty mistakes along the way, haha. Waning!! This mod cannot be undone, and is risky, overall(you might ruin your headset).
