Why does Super Sonico always wear headphones?


Just as the title asks, why does Super Sonico always wear those headphones? Is
there a reason behind it, or is this just the design Nitroplus came up with?




I discovered an interesting piece of information to add to Dimitri mx's answer
while I was researching my answer to [Why is Super Sonico
famous?](https://anime.stackexchange.com/q/23711/7579). It turns out that
Super Sonico was originally designed as the mascot for Nitroplus's music
festival, Nitro Super Sonico, as documented on [Super Sonico
Wiki](http://super-sonico.wikia.com/wiki/Super_Sonico_Wiki) and
[Wikipedia](https://en.wikipedia.org/wiki/Nitroplus). Nitroplus, though
primarily a visual novel company, had apparently held this music festival for
several years before they introduced Super Sonico as its mascot in 2006. In-
universe, Super Sonico is a singer (and gravure model, of course); she had
some very out-of-universe albums and singles released, which may have set off
the tidal rush of Super Sonico love that resulted in the manga, visual novel,
and anime.

So it made sense, when Super Sonico was first designed, to give her a pair of
headphones: she was the mascot for a music festival, after all, and a singer
herself. Dimitri mx's answer explains why she almost never takes them off.




I believe this is an example of the [Never
Bareheaded](http://tvtropes.org/pmwiki/pmwiki.php/Main/NeverBareheaded) trope
in combination with the [Nice
Hat](http://tvtropes.org/pmwiki/pmwiki.php/Main/NiceHat) trope.

Considering that Super Sonic is pretty much a half-naked model for Nitroplus,
the Nice Hat trope _" sexy"_ part does most certainly fit this description.
