It's a tale as old as time: how do you easily tell which headphone goes in your right ear and which one goes in the left ear (without reading tiny text)? You could always mark them with some tape or nail polish, but Lifehacker reader animatorgeek has another clever solution.

I have a lot of old earbuds and a lot of them seem to have the same shape of silicone thingy that fits inside the ear. You can take that silicone thingy and swap it around between different-coloured earbuds and end up with a set with two different colours. Now it's much easier to know at a glance which side is which. For instance, on my set I can easily remember that grey is left and black is right.
Just a small tip for those that have a number of different (coloured) pairs.
