    Pros: One egg for prompt delivery

    Cons: Very disappointed, cord and sound very poor, my iPhone 5's headphone much better, even Altec lansing's for $12 is better, waste money

    5 out of 5 eggsEargasmic

    Pros: -noise canceling
    -amazing bass
    -clear, clean sound
    -firm in-ear fit
    -durable cord
    -perfect for working out, won't fall out. (strenuous activities and such)
    -built in remote is amazing (works with my iPhone 5)
    -adjustable ear piece to fit what feels good to you (see cons)

    Cons: -Removable earpieces are easy to lose (pulling out of pocket may get caught and come off)
    -pricey (but totally worth it)

    Other Thoughts: I've had these type for over 2 years now, the S4i II I think it was (accidentally blew out left earbud speaker, completely my fault) they were with out a doubt my favorite and the best earbuds I have ever used. I was devastated when I ruined my last pair and was thrilled when these came on sale.

    I work out regularly and these are amazing for that and other similar activities. If you want a good pair, and probably the last pair you will buy (unless you're dumb and blow out the left earbud like I did) then do yourself a favor and BUY THESE! I can't hear anything with these in, even at low volumes I am dead to the world. I love love love these and will only buy these if I need new ones again.

    4 out of 5 eggsExcellent Sound, Mediocre Build

    Pros: There headphones are one of the nicest earphones I have worn from Klipsch, from having owned older pairs of headphones these felt nice and fit into the ear. The older pair had a heavy wire that made the headphones feel like they were constantly being pulled out, but this is not the case for these headphones. Klipsch seems to be constantly changing their wire design and these wires are a thin clear design. Being thin wires, these tangle easily, which is solved in their newer headphones which feature a ribbon flat cable.

    The headphones don't muddle the sound with too much of anything and have a decent balance. The headphones fit into your ear nicely and block out a decent amount of sound, not the most but enough to enjoy your music comfortably without having to turn up the sound to max. There is also a mic built into the remote which is good at picking up your voice even if the remote isn't clipped to your shirt.

    The headphones also come with a metal tin carrying case, this might also be a con as the tin can't really fit the headphones with the weird foam insert. The tin is also a bit bulky so it isn't very feasible to carry it around in your pocket. The newer S4i (II) has a soft carrying case rather than a tin.

    Cons: I had to knock 1 egg of for the build quality. The rubber used in the headphones wear down and split apart where they are closed together. These do not affect the actual performance of the headphones (as far as I know). The little piece that connects the 2 earbud wires is also made of rubber so it is typically the first rubber piece to break so its a contributing factor to the tangling that can occur in daily use.

    Other Thoughts: I also have an android phone (LG P990 2x) so the center button works for it. The volume buttons don't work but they have an app that allowed for control of the volume by pressing and holding down the center button. Also note, the difference between these headphones and the normal S4i are only color as far as I know/have read.

    Although the rubber can wear off, the headphones themselves are nicely built and I am typically careful with my headphones so for those guys who are rough with their headphones they might not last as long, but fear not. For Klipsch gives a generous 2 year warranty with their headphones. I have already had a replacement set mailed (with free shipping) and received the newer S4i (II). Normally I wouldn't consider warranties in product purchasing but Klipsch gives a 2 year warranty making even a full price a good deal when it comes to headphones. I always see friends replacing headphones every few months and by buying these you have ensured fantastic sound for 2+ years.

    Pros: Good fit. Amazing sound. Great bass. I workout and it's a perfect fit.
