Of course they sound better, thats what the marketing said. (honestly not sure it is a difference..), however the cable is very thin, light and flexible compared to the stock cable so i'll gain in comfort and sound will not be worse. I would not like to do an blindtest, (no one really wants to do that with their expensive cables)..
But hey it's actually a silver copper hybrid and we all know silver let's out the details in the music and copper makes the bass have more impact :-)
Seriously, equal or possibly little better sound and increased comfort is enough for me and it looks good also!
