The quality of the strings is something you'd expect from D'Addario. No flaws, whatsoever. As the specs promises, there is really reduced finger noise occurring from position change. What comes to timbre, to my ear there is too much rustle coming from wrapped EADG strings causing some imbalance with trebles B and E. I can imagine that this kind of effect can be used for something on purpose or go well with some specific types of playing or guitar models. Just not my cup of tea.
