As the title implies, they sound great. I have been practicing Layla (unplugged) for a while on strings from D'addario, but I was missing that Clapton tone. After switching to these bad boys, I kind of got it! 
 
Pro's: 
- Clapton tone 
- Nice strings for fingerpicking 
 
Con's 
- Not so nice for strumming, at least, I prefer the D'addarios; those are a bit brighter.
