yes, those are very close to what i have.
went back to the massdrop/drop listing and it was the "VENTURE ELECTRONICS MONK PLUS EXCLUSIVE BLUE" drop. the extras that were included were called the "Ex Pack" here's an image of what was included. you can see the ear hooks/fins that were in this set. i've used these on my monks since i got them over 2 years ago.
