I always buy these strings and decided to buy this bundle because you get three packs of strings in this bundle, so you save a bit.
I don't think that this is a good idea to explain their sound. You can find a lot of comparisons on Youtube
In general, they aren't bad, but aren't Elixir, which cost twice the price of 1 pack of those strings.
They are good and stay much longer than other brands (Dunlop, Ernie Ball, etc.), I recommend them
