I received mine today and have been listening with them all day. Wow, the sound stage is the best I've heard with my limited knowledge and collection of headphones. The balance between highs, mids, and bass are better than I thought. They are very lightweight and comfortable to wear for at least six hours. Yes, I've been listening to them for six hours, plugged into my SoundBlaster E5 portable amp and my iPhone 6. The amp helps tremendously.
