En mi punto de vista el woofer le da un efecto extra o sobrado, ya que ayida a dar efecto de vibraciones en explosiones, bajos sonidos, etc. Great sound quality but even better is if you sweat buckets in the gym like me (cardio, cardio, cardio x twice a day) then these are perfect. No weird unexpected connection with other devices. Work as expected. Overall not impressed for spending what we did. It does look like the price has gone up considerably since then, so Ill be scanning Amazon for rock bottom prices in order to feed my kids addiction AND still be able to drown out all the noise of life in the background myself. Super cute pair. There are shelves to put shoes or purses or whatever. Then I could have gotten something with direct drive that also played 78s. Makes it super easy to move one bike out of the way so you can access another.
