Every day I see people with headphones riding Metro, but this guy is really taking it to the next level! He must really value his sleep or silence. I am pretty sure that he is wearing the type of industrial earmuff hearing protectors used at a shooting range, or when operating heavy machinery in the yard. Just found the entire situation to be rather curious and wanted to share it. Ohhhh 6:00 am is always a fun time to be riding the trains.
