What a beautiful set! Very rich but warm tones. The black nylon strings are super jazzy. Took a few days to fully settle in, a few months in they stay in tune better than any strings I've ever had! The golden bass strings feel amazing to play, very smooth and they sound full. Length of ringing out I'd say is about average compared to all the strings I've tried. However so far they've worn out slower than the rest. All in all I love them! I am definitely buying them again
