The '225x headphones deliver Grado's signature sound: they're quick, warm, and well-balanced. To achieve that, they use Grado's new X Series drivers. The new driver design has a lighter voice coil, redesigned diaphragms, and a more powerful magnetic circuit. All that culminates in a pair of headphones that can keep up with any tunes you throw at them and heighten your musical experience.

Grado redesigned the headband and beefed it up with extra cushioning to improve comfort. They also made the cable more durable on the outside by thickening the jacket. On the inside, its super-annealed (heat-treated) copper wire improves signal transfer and purity.
