I have never spent any substantial amount of money on headphones for a mobile device. Having oddly-shaped ear canals, as well as a penchant to break "nice things", I usually stuck to the earbuds that came with my walkmen, discmen, MP3 players, and eventually phones. I listen to most of my music in the car or at home, so it was never a big loss for me.
That was, until I was given a pair of S3m headphones from Klipsch. I'm aware of their presence in the high-end audio market, but I had never had the opportunity to purchase any of their products (read: couldn't afford,) before. Priced at around $50, they're pricey enough to be a premium item, but affordable enough to keep me from feeling that I'm a dang fool for buying them. (Some of y'alls kids are spending $300 on Doctor Dre headphones. This is a problem, and also likely the reason why Detox will never get finished.)
Here are just a few notes on the product:
FIT: As it comes with 3 pairs of ovoid eartips, you should be able to achieve a fit that is snug, comfortable, and "sealed", for lack of a better word. As I said, I have some oddly-shaped ear canals, so I do get a little wiggle in my right ear, but I've yet to have it fall out on me whilst walking, as every other earbud I've owned has.
SOUND: The drivers in these buds are amazing. Obviously, you can probably pay a lot more money and get a bigger sound, but given the size and the price of these headphones, I was blown away. I listen to a wide variety of music, usually surf, folk, classic rock, jazz, and blues, and I've noticed that the sound doesn't muddy up from one mix to the next. Live recordings on these buds are particularly brilliant.
ETC: The cord is sturdy and long. This has been a problem for me in previous products, as I'm a sizable chap and have a long distance to my pockets. I've found the eartips to be fairly easy to clean, and haven't had a gum-up problem yet. I honestly don't use the control much, but I've made a few calls using the mic and have had great success with it.
So all-in-all, these buds have certainly been worth $50 so far, and look to give me a long life of use. I don't worry about breaking them, the wire getting damaged, or the drivers going out. As I said, I still have that slight wiggle with the right bud, but I daresay it's not Klipsch's job to perform surgery on my ears. I may actually switch up to their sport model at some point, but for right now, these are fantastic.
