The products in the OP are all heavy overpriced. Best value you'll get with Sennheiser MM 50 iP by far. It's not only a headphone but a headset and you'll get much more functionality for your iPod Touch. You can make use of all sound recording apps! You can make Skype (or other VoIP service) calls. The sound quality is superb! And I have lots of experiences with headphones and headsets.
Attention! There are lots of cheap imitations out there (plagiarism, fake) and they sound aweful! Get it via Amazon.
Please have a look at this very detailled and informative website (the example there is a very similar Sennheiser headphone):

For me personally the asymmetric cables are ingeniously once you've got used to them. Yes -- as mentioned before -- the tiny mic is larger and heavier than that of Apple headset but it never caused that I lost the headset (and I am using it really frequently everyday). It's better rounded than Apple's so it won't get hooked at zippers etc.
A friend of mine has the latest original Apple headset for iPod Touch and I've tested it: The sound quality is weak compared to the Sennheiser headset. Very weak.
The cables of MM 50 are rather thin and vulnerably but the whole set is extreme lightweight. The impact sound insulation is not very good, you can hear noises when you move (when the cable hits somewhere) but the solution is easy: Switch the music a bit louder ;-) The sound insulation in- and outwards of the ear buds is excellent. For me the very soft silicon buds fit perfectly. They are easy to clean and you can buy them separately.
Have a look at my review -- sorry it's German-language but there are some high-res images in it.
