This speaker is great! But this pair of earpads completely changed the sound signature of the headphones. I got these headphones since we are doing online school. will make a great birthday present for my fiancée. La calidad de sonido muy bien los bajos son se oyen excelente, ideal para ejercicio al aire libre en mi caso para salir a correr y andar en bicicleta, tienen buena sujeción. What got me was the case that it comes in, thats how they make up for not being a better quality product. mio figlio le ama ottime per uso piscina non si bagnano. Im about 52 so it was a bit too long for me (squeezed in my hips too which I did not like) but other than that it snatches up your waist real good. You can also visit their website for help. Only brand he cares to wear.
