I can tell from the design that I will never wear those ear buds. There is no way to create a decent seal in the ear using just hard plastic, so the sound will suffer for music, and that's the main reason I buy earbuds.
I'm not a snob about music stuff, but for around 100 USD I get a decent pair of earbuds that create a proper seal and gives me good music quality. I'd love the features, but I'm not going to sacrifice the main reason I use in-ear headphones in the first place - the ability to relatively cheaply have good quality sound.
