This is a quick and easy cover that slides (and is held with friction) onto the blue LED on the front of Kanto YU2 speakers. I find it distracting and this removes the shine.

There are other solutions available online for this problem, this is hardly original, but the other one I found did not fit my LED (mine is a 2024 model, maybe?) so I just made my own from scratch. I'm not sure if this works for any other Kanto speaker, let alone speaker type, but it's a quick print so should be easy to tell!
