    Comfortable, natural sounding phones for critical listening.

    Saw a detailed video on YouTube that showed, with graphs, how good these phones are. The price was great so I went for them, after months of researching for new phones. These are not "consumer" grade phones; meaning they have not been tuned to enhance any frequencies. They are meant to be reference headphones for studio use.

    Buena referencia para mezclar.

    Un buen producto para mezclar, considerando el precio . ligeramente brillante lo cual ayuda a escuchar con mejor detalle, para los ingenieros que mezclamos es util. la resolución puede mejorar si lo comparas con audífonos de mayor precio, pero por el precio pagado es muy buen producto. Son cómodos ,y podrían mejorar el acabado , pero seguramente costaría mas.
