I was happy and my son too. So in summary, these earpads totally ruin the overall sound quality of the m50xs but increase the comfort factor, and for the m30xs, they 100% increase the comfort factor and increase the sound clarity a little, for me at least. I love the style of shoe, a slip-on sandal with no back, so I will keep it, but was disappointed they are not like the original. Samsung Pay es imposible usarlo en el reloj, ya que solo es compatible con tarjetas de estados unidos, si tienen ya un teléfono con Samsung pay y tarjetas añadidas, no lo van a poder usar, el reloj les va a pedir que verifiquen la tarjeta, y lo intente llamando primero a citibanamex, ellos me dijeron que llamara a Samsung pay, y a la vez ellos me dijeron que no podían hacer nada ya que el reloj fue comprado en Estados Unidos, me pidieron comunicarme con Samsung Estados Unidos, lo hice y me dijeron My feet are a bit wide and I usually wear normal width in Birkenstocks. I am not handy and dont always think ahead when putting things together. The Amazon price is great for these also. I’m really disappointed. These are very uncomfortable. Also the earcups are very small and my ears don’t fit inside fully so hurt after a while
