They were comfortable, 20x as comfortable as the Momentum, and about as comfortable as the ES FC300. Build was expectedly fantastic
Sound wise... well, there was nothing to complain about. They were good, about as good as the momentum. They weren't very enjoyable. At least the momentum is intimate, so it sounded different.
The ES FC300 is definitely what I prefer. Best bass, and a wonderful soundstage. Please someone buy them!
