They were my first decent IEM and if you've never heard anything but cheap IEM's you get at Walmart or what ever than they sound fine but once you hear a good IEM then you can easily hear their deficiencies.  So if this is your first IEM upgrade its not to bad of a choice.

You might want to see about getting the Sony MH1C which is only $25 and they sound very good not just for the price but compared to IEM's cost over $100.

I wouldn't put to much stock in a Cnet review or reviews on Amazon, if you want real reviews this site and a few others are the way to go and there's also some good blogs but your not going to find many reviews for the S4 as its just not that popular on Head-Fi.

Before joining this site I also got suckered into the S4 by some reviews including the Cnet one. I keep them to remind me how bad they sound in comparison to the nice ones I have accumulated.  I second Techno Kid's recommendation for the MH1C's.
 

The S4 was my gateway to higher end IEM's also.  If it wasn't for the S4 and even Beats there wouldn't be as many people getting into the high end and more audiophile type products.  Even though they don't sound great compared to a lot of IEM's and headphones so just the fact they introduced people to quality audio is a very good thing. 

Like Sycho said, we improved the durability and design of the entire S4 family and cleaned up some of the sibilance at the top-end.

I've no complaints about the sound quality nor the durability, although I've only had these for a little over one month.

My issue is the Klipsch Android app for the controller.  

This is universally acknowledged as a 'crap app' by owners of the many popular android devices that the Klipsch app won't work for.

When will the updates be ready for the Motorola Razr in particular?  What will happen when Jellybean rolls out?

Great sounding earphones.  Great price.  Lousy app and device support.

"Universally acknowledged" is a very strong and unfair term seeing as the headphones are compatible with a ton of the most popular Android headphones out there. Also, it is very difficult to make any accessory compatible with ALL Android devices due to the incredible amount of fragmentation both software and hardware wise.

Cannot 100% confirm right now but I have been told that the Jellybean update should fix the issues with the Razr.

U guys can try the headphone remote control app! Or other similar apps to customize how the buttons work into Android!

May I ask whether this earphones also work on a iPod Nano?  I got both a Samsung Galaxy S3 and an old iPod Nano which I also often use.

Thanks!
