• Comes in that stupid plastic packaging that causes you to lose a finger trying to knife it open
• Comes with a clip
• Comes with a rectangle thing with holes in... think it's a storage device.
• Comes with a cool Sennheiser bag
• Noticeable improvement over the Apple iPod earphones almost immediately
• Bass!
• Non tangle cabling similar to Sennheiser's headphones
• Couldn't find a bud suitable for my left ear! Comes with lots of buds, though.
• Being in the ear blocks other sounds
• Takes more time to take out and put in
• Seemed to fall out more often when moving around

Overall I am quite impressed with the earphones. I don't know if I will continue to use them at work, though. Cancelling out sounds completely means people have to shout at me to get my attention.
