EXCELENTE CALIDAD Y PRECIO.

Tengo poco con ellas. Suenan muy bien. No son tóxicas, pregunté a MARTIN directamente y me respondieron que solo usan materiales que no tienen riesgos para la salud, lo hice porque leí un comentario de alguien preocupado porque deja manchados los dedos, lo cual a mi no me ha pasado. Lo único que no puedo precisar es cuanto duran en realidad, pues tengo poco con ellas. Estoy convencido de que fue una buena compra.

They don't last long

Nice bright sound but after only 2-3 weeks they start to tarnish and lose a lot of brightness in the sound. I expected better
