Yes! I bought the clear a month before getting the HD660S. I ended up selling the clear and keeping the 660S. The main problem I had with the clear was a shouty, fatiguing midrange. Also even though the bass was more extended with the clear, it was not as present as with the 660S. The 660S has way better imaging as well and a very slightly wider soundstage. In the end, the 660S is fun to listen to and the clear was not.
