Lend Me Your Earphones

Samsung may be making http://www.cultofandroid.com/72012/samsung-ripping-off-apples-earpods-galaxy-s6/ for the S6, but they would probably cost about the same. You could check eBay for people who have only one pair to sell, i.e., are getting rid of an extra set that came with a new device. Those with multiple cheap "Apple" earpods are likely selling counterfeits.

I have been meaning to try the Amazon Fire headphones after readinghttp://gizmodo.com/the-amazon-fire-phones-headphones-are-what-all-cheap-ea-1610385757. They might be for you.

Amazon has them for http://www.amazon.com/exec/obidos/ASIN/B00LIG80CA/metafilter-20/ref=nosim/ they are by far the best and most comfortable earbuds in that price range.

* There is a chance that they are fakes. If they are then they are really good fakes because I couldn't tell the difference.

Seconding the Amazon Fire headphones. Sound quality and build quality equal to the Apple ones, but they include a volume control that works on my Samsung S4 (unlike Apple) and are reasonably priced. Best of all, they have a fairly effective tangle-free fancy magnet mechanism. They are by far my favorite earbuds. (I can't stand ones that create a seal around your ear with rubber gaskets.)

Monoprice!

Another vote for Amazon's earbuds but only if this is to be used on an Android device (unless you don't care about the remote and microphone not working right). The sound quality on them is quite good for the price, and the cord and magnet really do prevent tangles and rat's nests. Otherwise, I wouldn't risk trying to buy Apple earbuds at a discount. I learned my lesson the hard way by buying counterfeited crap once.
