Summary: To clarify: I have the normal s4, not the inline mic/remote edition (these http://www.bestbuy.com/site/image-s4-stereo-earphone/9422369.p?id=1218105502820&skuId=9422369&st=klipsch s4&cp=1&lp=3) I picked these up the other day just for the heck of it and because of their legendary status as excellent budget iems. I really wasn't expecting jaw dropping sound, especially since I was currently pricing some iems several price brackets above these.
Pros: exciting sound, comfortable and light weight, excellent design and quality, shiny!
Summary: I got a pair of these to use with my iPhone for listening to music as well as making calls. So far I'm pretty pleased. I agree with raghunath that they are a little bassy, at least compared to my last cheap pair. But I don't mean that in a bad way. I like the way they sound.
They're a very comfortable fit and come with 4 different sets of plastic tips in different sizes so you can use the one that fits your ears best.
Pros: Sound good, Comfortable, iPhone-compatible
Cons: large button, ear mold plastic could be firmer
Summary: I believe this set of earbuds provides an extra level of clarity that allowed me to hear the emotion suddenly enter a person's voice, something that had eluded me in the past. I'm also glad for the longer cord. The earbuds themselves are angled oddly, but that may help the clarity. I think I may need to add the larger rubber earbuds, as sometimes it feels that they're going to fall out. But I cannot figure out how to get the replacements on. There seems to be a system.
Summary: I bought the klipsch s4i along with the iPhone4 on iPhone4's launching day cause I thought my new phone deserves a good earbuds. Boy was I wrong. klipsch s4i is nothing more than a piece of sh*t! Please excuse my language or if I offended any klipsch fans, but im just trying to speak of my mind. The sound will break when the note is too high and there is absolutely no bass.
Summary: These will provide very good isolation if you get the correct fit. I managed to do this by trying out all the tips affered. As others have noted, the is a little bit of distortion on the highs, which I've noticed slightly affects the vocals. The bass on these is really good, altough it fortunately doesn't drown the rest of the sound, which makes them a little balanced to my ears. Overall good value.
Summary: This was the first pair of headphones that I truly fell in love with. I remember it like it was yesterday, I asked my roommate of I could borrow his headphones while I studied for my upcoming computer science midterm. He handed me a tangled mess of black rubber wire, and said "here, they suck but they're the only ones I have". Laughing, I put them in my ears, and was surprised at the immediate ease of insertion.
Pros: cheaper than Ethiopian dirt, good construction, glorious bass, perfect fit.
Summary: I really like these earbuds. they are a huge step up from the crappy skullcandys that I bought a few years ago. They are a little bass heavy, but that doesn't bother me. I love the in line controls, they come in really useful. I didn't rate the mic, though, because I don't use it. They work great for me and I think anyone would enjoy listening to them.
Pros: Sound Quality, bass in particular, in line iphone controls
Cons: can be a little uncomfortable after a long time (2+ hrs)
Summary: These were the last in-ear headphones I bought before I decided that I just can use them without feeling like my head is in a vice. That being said, these were the most comfortable vice-like in-ears that I found. Klipsch always prices their products very well and these were no exception, the sound quality for a pair of sub $100 headphones is superb. They were very good at isolating sound as is the way of most in-ear headphones since they're pretty much ear plugs.
Pros: Price, bass, ipod controlls
Cons: cannot be worn for long periods of time, missing treble
Summary: I got these about 7 months ago and I use them to listen at work. I have a very borring job and these really help to brighten my day. The mids and highs are gorgeous. The bass is good too but I would not reccommend them to a person who oppsesses about bass. The ear bud tips are klipsch signature but I would say they need improvement because I have to take them out of my ears often. They are amazing for the price and I loved them while they lasted.
