just got my black one today. if you didn't know what it is check replug.com basically it prevents you from destroying your headphone port if you happen to yank it too hard from an angle perpendicular to the port. lemme say it takes a good amount of force to pull the bloody thing off, and it can be pretty hard to plug back in the plug part. other than that the middle part bends which gives it some nice give to light yanking. one gripe is that the plug is not gold-plated, which conducts less interference. it's a little steep with shipping but with the invishield it really gives piece of mind.
