Grado’s audiophile following is sure to grow even bigger than it already is thanks to the introduction of a new 4th-generation X Driver for wired headphones that capitalizes on the introduction of new lossless music collections by services like Apple Music, Amazon Music HD, and Spotify Hifi. Grado’s new 44mm driver has been in development for years and is finally available for the SR60x, SR80x, SR125x, SR225x, SR325x models. The headphones utilize a more powerful magnetic circuit, a voice coil with decreased effective mass, a reconfigured diaphragm, upgraded cables, and thicker faux-leather headbands. And, the SR235x receives a new genuine leather headband. Now, there’s even more reason to get fully immersed in your favorite tunes.
