These are great sounding strings with a sweet tone that's leaning towards the warmer side of the spectrum. I particularly like the trebles but the basses are very nice too. The intonation is acceptable, which was a nice surprise after a very poor experience with the medium tension (black) strings from the same series.
Personally I prefer slightly higher tension strings but I knew what I was getting so I can't really complain. These are excellent strings if you like low tension. Of course, "low" is a relative term and Hannabach strings are usually slightly harder tension than you might expect from the description. In fact, these "low" tension strings are actually harder tension that D'Addarios "hard" tension strings so that's something to be aware of.
Highly recommended (but check out the tension figures on the packaging so you know what you're getting)!
