Excerpt: The sound is crisp and gives a different perspective on music. You hear every sound that the musician made, while getting a bargain for your money. Klipsch 40 dollar headphones have same impact as beats 150 dollar. That's says a lot about the product and the company! The design is smooth, where it's light and easily stays in your ears. At the same time, the warranty is off the charts. The company puts emphasize on making sure that your product will be fixed.
Summary: This is a great set of ear buds! I am the voice of "Newsfix". An anchor less newscast out of Houston, TX. I recently began wearing the S4i's in favor of $400 Sony's in my booth reading news stories 6-8 hours a day. First, my head is no longer sore from the large cups squeezing my skull all day, but more importantly, these buds with their very realistic sound reproduction have increased my efficiency and quality of reads...
Summary: I paid $65 on Amazon for the s4i's. I've tried many more expensive in-ear headphones and these Klipsch sound equally as good. Two channels per ear, with nice separation - clean, not tinny treble, and moderate, tight bass (when seated in ears properly). The sound has a fair amount of spaciousness especially with lossless music.
Summary: great sound pleasure... but i'm not sure yet of the durability of the cord. I feel that it's too thin that it might break easily. It will be tested in the coming months. Thanks Klipsch! (bought on October 28, 2012 at The Listening Room, SM Megamall. Philippines). Serial No.(?
Summary: These headphones have some of the best sound. The base is definitely better than the in-ear Bose headphones. I've only had them for about a month, and I worry about the durability--but the warranty seems good. I also agree with another comment that it needs a better carrying case. It probably also should have a skip function on the controls, but I bought it for good sound, and so I am satisfied.
Summary: I love these! I have never owned headphones with such good audio and mic. These by FAR beat the beats I bought before these. The bass and quality is great, even at max volume on my iPhone. I LOVE the mic! It is amazing! I use it when i'm on the phone or listening to music or playing my games.
