I prefer headphones to earbuds because of the comfort. 
Oh, what's the most popular brand of headphones?
Beats electronics is popular. They are a division of apple though so that is to be expected. 
How much bass is in them?
I believe they are adjustable. Bose makes great headphones too. 
When was bose founded?
It started in Massachusetts as a privately held company. 
Very cool. How expense do headphones get?
They are expensive but they have noise canceling ones called quiet comfort that are worth the price.
