It's still very early and I need to do a lot more listening to different things. I've only sampled 20 songs or so and nothing else. I still have no idea how they compare to the X1's in gaming, movies, etc. However, I will say that I am impressed so far by the detail of the AKG and the balanced sound signature. I will post a full-blown review with a detailed comparison of the X1, AKG Annies and DT 880s in combination with the ASUS Xonar Essence ST, Creative X-Fi Titanium HD and Schiit Magni in a few days. I will test music, games, movies, and youtube videos.
looking forward to the final review. helpful that you have the same amp, i enjoy my akg 702-65s but have always had my eye on the x1. should be interesting.
