Question: Is this product compatible with Apple Classic I-Pod?
Document: Sound quality and comfort are great. My only problem, and the reason I can't rate the product higher, is that the remote is not compatible with my 160 GB iPod (6th generation)--confirmed by Klipsch, but not really made clear in the product information that I could find. It's supposed to be compatible with iPod "classic," but apparently this doesn't include the 6th gen. Remote works fine with my son's iPhone, so the remote works.
I have tryed all the different sized attachments and they dont seem to stay in place, I had high hopes, and was very disappointed. I will add that this may not be a reflection on the  quality of the product, but this style headphones may just not be compatible with my ears.
I initially bought these looking for a simple replacement for the Apple in-ear headphones that I had lost. They looked relatively sleek and promised to be noise-cancelling so I thought why not for such a cheap price. I'm thoroughly happy with the product and the sound is pretty good to me (granted I'm no audiophile) but it blocks out nearly all background noise. I will say, however, that this might not be the best choice for workouts...
I have used the mic in a variety of different positions and orientations but it makes no difference. The Apple standard mic was far better at filtering out ambient noises and conversations than the 4Si.If you are primarily seeking a good earphone for music and rarely use it for calls - I highly recommend this product. If your primary purpose is phone conversations, you'll be able to hear other parties very well, but they are more likely to hear those around you more clearly and louder than you.
The ear phones are really good and value for money,the spacial curved shape of ear phones makes them fitwell in ears, no stress or duress to ears the noise cancellation is excellent. The quality of sound in excellent. The flat wires doesn't entangles, which is a big relief as the stock Apple's ear phones have wires always getting entangled. The remote works fine with all Apple products, I have tried with Iphone5, Ipad and Macbook Air. All in all a good product.
I bought these for a gift. The recipient reports quality is good & really likes them, even though they are not fully Android compatible.
Klipsch will most likely have a new, compatible model out soon, so if you're running iOS7 and you want a working remote, wait until then to buy.
the sound quality is inferior to my marley ear buds and not much better than the free ones that came with the i-pod
make sure you get the ones compatible for your device. I accidentally ordered the ones for Iphone although I have an android phone. Since I have the incorrect ones my buttons are not correct. mic works and start/stop works but not volume control buttons.very comfy and good sound. loud cord noise though! I have to wrap the cord around my neck so the cord noise does not over power the audio.
My audiophile brothers suggested I try these when I was in the market for a nice pair of in-ear headphones that was compatible with my iPhone 5. Compared to the OEM headphones, the S4i II's are immediately much more clear and crisp. It sounds like there's more frequency extension at both the high and the lows. Instruments like cymbals and high hats re more evident, and the low end bass is more defined.These are in-ear headphones that come with 3 different adaptors to fit your ear size.
Answer: The input connector is 3.5mm (male type)--so if that is what you are currently using, it should work. The Klipsch site specifies that these earbuds are compatible with iPods. I use these earbuds on my iPod Nano. I like everything about this in-ear headphone. The sound is far superior to standard Apple earbuds included with my iPod nano.
