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. 
When was noise canceling invented?
