These ear buds are great! Excellent sound quality, good rich bass. My only complaint is that the wire is kind of unruly. It is stiff and doesn't roll up well. The durability seems to be very good though. I have had these for 7 months and I have no problems. I am very hard on earbuds and they usually break after a few months. Maybe it is that stiff wire that I am complaining about that is keeping it together. I don't know, but If the stiff wire is the price I have to pay for durability then it is well worth it.

Side by Side tests by myself (52), my son (26) and his friend (26) found no real difference. Their unbiased opinion slightly favored the $5 spare in-ear-phone over the S4s.

These are pretty much a bargain. The sound quality is up there with much more expensive headphones. It might take a bit of fiddling to get the correct fit with the correct size ear piece but it's well worth it. The only quibble I have is that the cord stays quite stiff and can be a little awkward. But that's a minor issue - they are well worth the money!

I have been using this for 6 months now. Works great and sound quality is nice. Their customer service was awesome too.
