The other day, I left my earphone, so I tried walking while listening to Youtube on a smartphone without a earphone.
On the way to my home at midnight, I was walking while listening to the Rakugo of Mr. Yanagiya Kyotaro, with setting the volume to the maximum.

Trying it out again, "without earphone" is a pretty good thing.
First, it is not troublesome
Wearing something on your ear is pretty annoying.
It is safe.
It is safe and secure I can hear the sound of coming a car.
And it is secure.
"A business worker bursting laugh at rakugo in a late night road"
Who want to approach me?
Well, though, I cannot think where a curious person is, who tries to attack a middle-aged man in the late night.

However, I think that this is quite effective for security reasons.
On the late afternoon home, I recommend my daughters to take this way.
I think "Rakugo" is also good, and "English news" is also good.
"Heart Sutra", "heavy metal", "nursery song". Surprisingly I think that 'Enka' is also good.
I think that "idol songs" and "animation songs" are not very effective, so I will tell them to stop them.
