I was very disappointed by these strings. After hearing so many good things about them, I decided to try them out. Expensive mistake. They sounded cold, scratchy, metallic, and shallow, yet mellow at the same time. There was some resonance, but not as much as many other cheaper strings I've used. Another big issue I faced is that they squeak and screech very easily. While playing, the slightest accidental bump of a second string lets out a loud squeak. I have not had this problem with other strings unless they're really old.Overall, they are not worth the money. I'd value these at about 1/3 the price of what they sell for. They're not the worst viola strings I've ever used, but not even close to the best either. They're definitely the most expensive I've ever bought though.
