Suffisant pour regarder la TV, jouer, écouter de la musique dans les transports. I wore them after abstaining from high heels for several years. I like that they are available in wide because my son has wide feet for such a little person. They lasted that long with Heavy, Everyday wear. Helps me from dropping and/or scratching up my case. My feet thank me with every step! The sound isnt quite as deep as other earphones I usually wear, but overall its decent. Problem is, my feet always get cold when not moving due to poor circulation. Yo los recomiendo 100%100 me encantaron desde que los miré se ven tan hermosos en mis pies, una ves que tengas los tuyos te vas a enamorar de la comodidad para tus pies porque si algo debemos cuidar es la comodidad de nuestros pies. The built-in cable lock for each bike is very easy to use and I am sure an excellent deterrent for thieves.
