Airpod support wireless connectivity and also smaller in size compared to headphones. But on the other hand Heading do boost flexing vibes quite more for me than airpods. 

To be precise I love airpods quite more than headphones  because of the size. I don't need too much weight on my head. Also most headphones seizes sounds from environment making it not possible for you to hear others speak while using.

Which Do you prefer using most, is it airpod or headphones?
