Finding Left and Right
by Satish Krishnamurthy
At some point in time, we have all been frustrated with earphones, and my biggest peeve has been the L, R mismatch. I loved a few earphones for their sound, but the irritation of looking for that faded L and R, just so I can wear them right has stayed with me.
I bought these cheap Philips earphones because they partly solved the problem. But then, came the trick of remembering if L was Blue or Red.
And, when the L and R faded away with use, I was back to where I started.
A few months ago, I bought a pair of Sennheisers. Within a week of wearing it, I made a discovery!
With just a subtle structure change in L and R, this earphone incorporates a haptic differentiation. So now, I just have to run my finger along the edge of the earphone. If it tilts to the right, it goes into my right ear. If it tilts to the left, it goes into the left ear.
What better way to find L and R in the dark, you say?
