LR earphone / earphone

LR earphone

LR mark of an existing earphone is too small to recognize where its right side is and left side is, even it is invisible at night. However, now we have a new-type earphone being distinguished by hands, not eyes.
Have you ever experienced difficulties in recognizing between left side and right side of earphone because the LR mark is so small? LR earphone is really easy to understand because left side shapes like L and right side shapes like R. Therefore, we do not need eye identification, but just use your hand, even at night.
