Summary: They're shaped specifically for the left or right ear which is why hey aren't marked left and right. I've never even accidentally put them in backwards. I had no problem with them falling out unless my ears were wet. Even then I would just dry them and be on my way.
Pros: The have the best all around sound of any headset or earbud I've ever used. They're even awesome for BC2! The hybrid semi-active/semi-passive noise cancelling is top notch. Perfect for planes because it blocks out (to be fair) about 50% of the noise....without playing any music. You're in your ow...
Cons: I bought the 2 year protection plan because of bad experience with other earbuds *cough*ipod*cough*. Turns out I'm not gonna need it!
Summary: Contrary to previous poster's remarks, they are marked L and R on the under side. If your ears wax up easily, the buds get messy, and are difficult to clean (grab a paper clip). I wish I could have tried them before buying, I probably would have passed.
Pros: Amazing range, great bass when you get them situated just right. Light weight, good at high volumes.
Cons: These are awesome if you can get them lined up, and one of the three sizes of the buds fits you just right. The problem I have is I can't get them lined up just right, or if I do, they fall out of place with the slightest of movement. This is with all 3 sizes. Also, the smallest buds produce horr...
Summary: Get this for your electro-heavy music, but don't rely on these for vocals. This pair of headphone will last you a very long time, unless you're bad at taking care of fragile things. DO NOT get these if you're clumsy as they will fall apart very easily from mis-use.
Pros: The sound reproduction is riveting once it's past the burn-in period; I think these are best suited for electro-heavy tracks, as vocals still don't have a punchy feel to it (even after a year+ of use.
Cons: The drivers started separating from the housing a few months in from light wear (no problem, I super-glued them back together). DO NOT get these if you're clumsy as they will fall apart very easily from mis-use. They don't come pre-burned, which could've saved the consumer from false accusations ...
Summary: A combination of the reviews, the Klipsch reputation, and the noise isolation feature convinced me to try the S4. I just expected more so I was disappointed when I first tried the S4. I recommend you wait for a 75% off sale or save your money.
Pros: Light weight, comfortable and reasonable sound. (Buying toys from Newegg is always a pleasure.)
Cons: Noise isolation is partial and is NOT active. There is slight noise reduction because you put them in your ear canal. The other ear buds I own that highlight noise reduction are active or noise cancelling for about the same price as the S4s. The S4s are not marked for left and right. Klipsch went...
Summary: Brought these way back in 2011 for what seems like a total rip off today of $80 or so.
Good: Bass, I think the bass is too dominant with these, it makes the mids sound bad and the highs are just absolute crap.
Pros: Bass, high quality, carry case, (comfort, isolation)
Summary: did not buy at newegg because i had a best buy giftcard but other wise i would have because newegg is the best. people are saying these are not durable but mine have been through the wash twice.
Pros: awesome sound quality when burned in especially compared to beats or bose great punchy base most comfortable iems ever made lightweight durable(cord is questionable) mine have been through the wash twice
Cons: cord is somewhat flimsy attract a lot of wax can fatigue ears after long periods
Summary: *** This is a person pet peeve...don't tell other people that these have horrible sound quality if you are listening to some low quality audio file rather than a CD or a lossless file. ITunes quality is getting better, but it is nowhere near lossless.
Pros: Audio reproduction is fantastic. You will be hard pressed to find another pair of in-ears anywhere near this price that uses micro-speakers that sounds this good. Very good tight bass without any sacrifice to the upper end of the spectrum.
Cons: Like other people have mentioned, the cable quality definitely leaves plenty to be desired.
Summary: I've had a very bad experience with these headphones and as such will personally not be buying Klipsch again. I'm now on my third pair of the the S4A (II)'s - the version specifically for Android smartphones. All three developed the same issue, losing sound in one channel.
Pros: Sounds half decent, bass not too woolly and treble not too harsh
Cons: Cable will fail you, even if you treat it like it an angel. Cost doesn't reflect quality.
