Strandberg Boden Optimized Strings 8

Something is wrong with these strings. Whenever I order these strings, I get they sound like they have been used before, muddy and bad. I must change these after one or two weeks. I don't know what is the problem, but obvious they don't sound well...In some rare cases I get fresh and good sounding string and for my second Strandberg I get dog s...t

Maybe a problem with humidity and packaging
