My favorite piece of technology

I don't really have some like a favorite piece of technology, but if i had to choose one, I would choose the headphones. 

 They are amazing, you can listen your music in every situation, you can use them whenever you want. 

 They are in diferents forms, colors, quality and size. Personally I prefer the headphones that makes you can't hear nothing except the music, they are so useful when you want to read or concentrate in something,  but the people makes a lot of noise. I don't like the bigger headphones, carry them is really unconfortable.

 When I'm tired in class, I like to sleep and listen some music with my headphones.
