These so-called "Extra Bass" earphones aren't as extra as much as they have radically chopped off the tops and haphazardly grafted it to the low frequencies and artificially inflated the basses.
I want my earphones to send me shivers through my skull whenever I reach that single bass note in Gorillaz's Clint Eastwood without making it sound like Del is rapping underwater through a pillow.
And yes, I know people are using this song to test their earphones because if you go to the album version on YouTube, there is a little bump on the audience retention graph around the 2:40 mark.
