I purchased a set of these for my wife, who'd been complaining that the Sennheisers that came with my Karma were uncomfortable. They arrived in a little over a week. Everything was well packaged. They came with a semi-rigid soft case, an airline adapter, a rubber spacer thing which has some unknown function, and small, medium and large rubber tips for the earbuds.

The sound difference is huge. I've never had an expensive set of earbuds, so I don't have a whole lot to compare to, but these put the aforementioned Sennheisers and my $20 Sony earbuds to shame. I've never gotten bass like this out of an earbud before. I'm definitely satisfied with the purchase.

Not having listened to any other highend earbuds, I can't tell you where they rank...only that they sound great to my ears.
