Iain I have a pair of Sony headphones which not only have an L on the left but also an R on the right. Because I didn't expect to find them, it took me a while before It twigged what the dot patterns meant.

One thing that's always impressed me is that they but a vertical line of 3 dots on one side of the head band to represent the Braille letter L. This means that you can correctly orientated the cans. This must be a very simple thing to do and I wonder why more manufacturers don't do it.
