Summary: Excellent earbuds. Have a pair of Klipsch S3's and I love them and still use them from time to time. The S4a's are my main listening source as of now and if they come out with a better set I will certainly be sticking with Klipsch as my earphone company!
Pros: Just a heads up for folks. There is now a newer model (S4A II) available direct for the same price and it appears that Klipsch controls the retail price as the ones listed here are also $99. Don't fault Newegg for the the price.
Summary: This is probably the best earphone under US$100, very good sound and excelent noise isolation! Mic isn't that good, but does its job! Klipsch software for Android is nice, but need some improvements. Works nicely though.
Summary: I originally bought beats by dre ear buds and was dissappointed that it didn't work that great with my droid phone. The sound quality was good, but the speaker to answer phone calls with wasn't compatible. I heard about the Klipsch headphones and have been extremely happy with them. Anyone, even if you don't own a Droid, would be satisfied with these brand.
Summary: I did an absolute TON of research to find a good pair of Android earbuds that had good quality sound for <$100, this was the highest recommended product I could find. I took the leap and bought them and I'm incredibly glad that I did. If you've been disappointed with the <100 market in earbuds, but don't want to spend >100 for some crazy audiophile earbuds, I can't recommend these enough. The sound is top of the line in this price range.
Pros: Great sound, very comfortable, works with Android phones.
Cons: They do not feel incredibly sturdy. The wires FEEL flimsy, that's not to say that it IS flimsy, and I'm not willing to throw them around to test how much it would take to break them.
Summary: Recently got my new In-Ear Headphones and love them! Fit nice and snug in the ear, no outside noise / interference. They sound amazing! I would recommend these to anyone looking for nice fitting headphones looking for great quality sound!
