they use it when its needed or when they feel it it has to come from the heart
solos
It depends on what you want from your headphones. Solos are cheaper and definitely don't break nearly as much as the studios. But the Studios are in my opinion a lot more comfortable and have a better quality of sound. They can also go a lot louder than the solos which means they can be used as mini speakers. Also, the Studios are much bigger than the solos and come in a hard shell case. Whereas the solos come in a lower quality case which (in my opinion) doesn't look as good.
In the plural, it's solos.
