Review: Certamente un ottimo prodotto per il prezzo di vendita. Suono pulito e arioso, meglio dare un +1 db ai medi e medio alti. attenzione ai gommini, dovete provare quelli che chiudono completamente il condotto uditivo e sentirete bassi, scena sonora e isolmento al massimo ( tradotto potete ascoltare la musica a volume più basso senza subire disturbi ambientali. vale la pena averli. Ps adesso ho anche le mx 880, le jays one+ e le klipsch S4A..... In ordine di resa le prime sono le Klipsch, pio le jays one+, poi le mx 880 e infine queste
Review: ¿Qué posición ocupa Sennheiser en el mercado de auriculares y micrófonos? Todo usuario debe saber que, en los grandes estudios de sonido y televisión solo hay dos marcas que se utilizan para monitorizar las grabaciones: AKG y Sennheiser. ¿Significa que estos son los mejores auriculares del mundo? Obviamente, con este precio, lo que obtenemos es un auricular de entrada recomendado para la escucha de música por la calle desde un teléfono móvil o similar, teniendo en cuenta, eso sí, que dichos dispositivos no dan una buena calidad de audio. Estos auriculares cumplen con creces y valen cada euro pagado. Si compras una baratija de auriculares, con sus distorsiones, vas a destrozar tus oídos. Lo único que no me ha gustado es que pueda regularse el sonido, no me di cuenta que tiene un potenciómetro para subir y bajar el volumen. Esto a la larga será un problema porque tienden estropearse, además influye con el paso del tiempo en la calidad del sonido. P.D. Son los terceros que compro, uno se dañó y el otro lo perdí, los anteriores modelos son los Sennheiser CX 300-II. Si no quieres volumen en el cable esa es tu mejor opción
