The brand has a widespread reputation. The music side has a lot of users and makes money and the hardware side is making a lot of cash selling cheaply made, poor sounding headphones. Apple don't make the greatest earphones so maybe Apple will set to the design and actually improve the Beats headphones and make their own in ear "earpods" better too.
Beats needs less bass and earpods need more bass. There must be a good middle ground.
