Portable mp3 players for the elders. These mp3 players contain more than 100 Korean pop songs especially for elderly people. (The most popular genre of music in these mp3 players is ‘trot’) These mp3 players are sorta a boombox mini for the elders in Korea. They sometimes listen their favourite songs without headset in public spaces. Hipsters!
They are cool.
They know how to enjoy their lives.
