While earbuds and wireless headsets are an ever-expanding consumer electronic market thanks to the proliferation of smartphones, on-ear cans remain something of a niche (unless you count Beats - I don't). Even more niche than that are smartphone-friendly on-ear headphones. And somewhere between particularly obscure red wine varietals from Germany and Super Audio CDs lies the selection of specifically Android-friendly wired on-ear headphones. (Not really, but I wanted to make a ridiculous analogy.) The point is, if you're looking for wired on-ear headphones with Android in-line controls, your options aren't exactly endless.
The big houses such as Sennheiser either still only make in-line control products for iOS devices, or like Grado have forsaken the notion of such things altogether.
