It really depends, klipsch s4 has it's own good point, but adagios offers better dimension effect =)
I have never heard the s4 but from what i have read this will be superior, it is a great IEM in the price range if you looking for an airy sound with good strong bass!
totally agree with you! i am really satisfied with this earpiece! i would give thumb up for the final audio for created such a good looking earpiece with great sound quality!
