That's it, my second (third, actually) pair died, they just give a horrible sound and the warranty is now expired... That made almost exactly one year.

That's really pissing me off! I even bought two sets of replacement ear cushions. Seems like the S4 just can't last too long...Will I have to buy one new pair every two years, and send that pair for replacement once a year?

WOW  I guess I really got lucky. My S4 are a year old now and no problems..............Yet.   Do you run/jog every day and really use them a lot every day??

I use mine several times a week when I walk my German Shepard in the morning but I have my Ipod in my shirt pocket and I am very carefull

removeing them from my ears.

Some news for you, guys!

After my second Image S4 pair of earphones died last June, I had bought some to replace them. They died last November.

What's more to say about this product? This is getting really annoying. If at least Klipsch upper ranges of  earphones guaranteed better durability, but I have no clue about that..!

 As usual, one on the channels ceased working definitely. This is usually announced by a dark and buzzing messanger called M. Hiss, that shows up a couple of weeks before.

Don't really know what to do after having the pair replaced : keep it or resell it and buy high-end x10 earphones? or just going on that stupid cycle of buying 60€ earphones per year..

 I am a very big fan of Klipsch products and have owned a number of their Heritage speakers designed by Paul W Klipsch, but this company that calls themselves Klipsch now is a whole different animal.

I bought a pair of Custom 3's a few years ago and within 3 months one of the channels went out. After being told I wasn't putting them away properly in the metal case I got another pair. After 2 - 3 months that pair did the exact same thing. I still have that pair and they are sitting in a drawer at home. I'm not sure why, but I went ahead and ordered a pair of S4's after reading the reviews, and literally on the 2nd day the right channel started going in and out on me. So after 3 pairs of Klipsch ear buds, and none of them working at the present time, I decided to look elsewhere for my earphone needs.

Can't blame you a bit.  0 for 3 isn't good odds.

 I have had a pair of S4 for about 4 years.  I like them a lot and they have held up well.  They aren't my "go to" IEM's but they are fun and do a great job with rock.  I use them at the gym and working in the yard.  I pretty much abuse them but they keep hanging in there.  I just recently purchased a pair of X10 on Amazon for $89.  After about 60 hours of break in I really like them.  Smooth and balanced.  I would suggest that you order a pair but with the bad taste in your mouth I can see why you wouldn't. 

Have you called Klipsch?  They have a good CS department and generally take care of customers with these kinds of issues.  Good luck,
