Por lo que si tegusta el rap o el hip hop quizá no los disfrutes mucho, hay unos sony por 1000 mxn inalambricos y tienen muy buenos bajos, en comparación con estos, la cancelación de sonido no ayuda para nada. Customer service is great! I have been using it for 10 days (daily) and I love it. I?ve only ever worn them indoors. Ich denke anders macht man die Verzahnung kaputt. She was so bummed. This rack, however, works VERY well and at this price, I am especially impressed with its robust construction, simple operation and stable performance. I tried them on when I got them and walked maybe a hundred feet if that much. We just received our rack and tested it out today. Also walked all day in Rome and London with these on and could not be happier.
