Annoying click sound with new MacBook Pro?

Hello guys! I purchased the 2016 MacBook Pro 2.9ghz I7 1TB AMD 460 a few days ago. That MacBook Pro had graphic card issues so I had to return it then buy another one (Exchanging requires you to set up an apple genius appointment which are booked for the next week).


So now I am on my 2nd MacBook Pro with same specs and the keys occasionally make an annoying click which my other one did not:




It sounds like something is in they keyboard, but theres not. I just took my new MacBook Pro out of the box.
