How come only Sony and a few no-namers make vertical headphones (the kind that go into your ear and has a band around your head)? Is it because Sennheiser and AKG think their earbuds are too easy to mod onto a band to bother? It's a big hit for me because most open-air earbuds fall out all...

Yes, terrible brand, but it seems like everyone raves about the sound on these. Are they really all that?
