Equal to $5 Maxells

The following review is for Reference S4, which is a part of the bundle you are viewing.

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.

Amazing -

The following review is for Reference S4, which is a part of the bundle you are viewing.

Some of the best earbuds I have ever owned. Really do sound like a high-quality pair of $300 headphones once you get them in your ear right with the right earbud. Klipsch is top of the line!

Excellent earbuds! except...

The following review is for Reference S4, which is a part of the bundle you are viewing.

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.

More than your money's worth!

The following review is for Reference S4, which is a part of the bundle you are viewing.

These are the best in-ear headphones I have ever listened to! From clear sharp highs to solid bass with great volume even from relatively low output devices, they are a pleasure to listen to. The angled oval inserts in small, medium and large allow for a good seal in the ear for good isolation from ambient noise. There may be better in-ear headphones, but I'll bet you pay two or three times as much for even a little improvement in sound quality.

Well worth the money!

The following review is for Reference S4, which is a part of the bundle you are viewing.

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!

Unequaled Value

The following review is for Reference S4, which is a part of the bundle you are viewing.

On my 3rd pair. This one is going strong for 10 months now.
Light music, heavy music, these buds can do it all.
I blast Metallica through and through and these fine headphones deliver it - practically with no signs of wear.
Excellent noise isolation.
They put speakers half as cheap to shame.

The following review is for Reference S4, which is a part of the bundle you are viewing.

The extra earbuds really helped out.
I was abducted by aliens once and my ears canals have never been the same. The extra earbuds allowed me to find an exact fit!

Excellent product for price.

The following review is for Reference S4, which is a part of the bundle you are viewing.

The S4 Klipsch headphones have a very similar sound quality to their higher price point versions. The only negative I would give this version is that the cord used is a pain. Stiff, not easily straightened. Not a huge detriment, but not quite as comfortable, as the cord can hang out in front or behind you and get snagged on things.
