The Sennheiser CX 680is are a set of portable in-ears with a remote and mic.


The ear buds have a slightly atypical design, in that they have a little rubbery claw that sticks up vertically. This should rest neatly in your concha, fitting just under your helix. Sennheiser calls them EarFins, but that's not very specific and sounds like more like a genetic defect than a headphone form factor. We're therefore going to exercise our journalistic powers and dub them helix fins.
