In Assassin's Creed Syndicate, there are a total of 32 collectibles, in the form of music boxes, known as the Secrets of London. By finding all of them, players can unlock Godlike trophy/achievement, and unlock the Aegis outfit (the best outfit in the game) for Evie.
Once you get close enough to the music boxes, you should be able to hear them, but you can also use Eagle Eye to detect their locations. Unlike other collectible items, you will not be able to purchase a map from a vendor to find your way. The E-store does have a map you can use, but who needs that when you can get the answers for free on the Internet? Once you have found all the music boxes, they must be brought back to Reuge's vault to complete the process and open access to the Aegis outfit. Interact with all the levers to complete your task, upon which you'll receive not only the outfit and your trophy/achievement, but also 4 skill points.
