Klipsch S4 (II) headphones are great sounding and have ample bass for my taste. What I really enjoy is the earpiece. The earpiece sensation is truly great. I can leave these in my ears for hours, not like other ear-phones that I have used in the past.
Naturally sound is subjective to every user, but the earphones I have used in the past did not have the deeper bass that these provide. Nice fit in ear...
I did see that the connector to your device needs to be taken care of, as the cord probably needs more protection in that area of care, so I do plan to reinforce that flexible area.
There is a sound of the cord, especially if you are walking fast and if the cords are moving with a lot of motion, but I normally use mine while relaxing or computer work. Docked a star for this. Otherwise for iPhone 5 these work great with its features. Gotta luv the sound these have. !!
