My 9980s arrived today. Only had a little time to put into them, about 15 minutes or so. My C&C BH came in so I had to play with that new toy as well.
The cord is flat and rubbery asymmetrical type.It feels a little like a smooth rubber band but without the spring.
Its an improvement over the 9927's cord that is trying to murder me in the tangled mess of doom. The volume control hangs about 2 inches below the chin on the left cord in a kind of awkward spot, but I have no plans on using it so it doesn't really bother me at all, yet.
Buds are very light with textured aluminum housing. The colors on the housing are nice and vibrant: Gun metal and Christmas red.
Tips are a slightly harder silicon than the 9927s and have smaller diameter opening.
For the 10 minutes I listened right out of the box they sounded slightly recessed in the mids and a little with moderately bloated bass. I'll burn them in and do some A/B then post some detailed impressions.
