Headphones at home, earphones everywhere else for safety reasons of course.

Headphones are much cleaner.

headphones....earbuds hurt me.

This.

Neither, hi-fi speakers

Depends really

It doesn't matter.

But Headphones sound much better.

Headphones for winter, buds for summer

Earbuds for mobile listening like walking, running, quick car rides.

Headphones for casual chilling, long car/plane rides.

I have both but I prefer headphones, especially when I always get my cord hooked on a door handle or something and instead my headphones flying off (like my earbuds ) they stay intact.
