One of the most prominent features of the ATH-W1000x is it's low register sound produced by a combination of precise engineering and use of handmade black cherry wood pieces to support a natural ambient sound. On the bass register, these headphones produce a textured base that accentuates notes and lower register sounds. Overall, the ATH-W1000x model supports a sound that some have called ‘romantic’ and ‘vivacious,’ providing a richness in detail that's readily desired.
