GMP 250

The GMP 250 is a dynamic closed-back headphone that sets a new benchmark in its class for powerful, precise audio. It is engineered for listeners who demand an energetic response, delivering exceptionally clear, deep bass alongside a finely detailed reproduction of the mid and high-frequency ranges.

Isolation, Comfort, and Design

Its closed-back design provides excellent isolation from outside noise, allowing you to immerse yourself completely in the music. Long-term comfort is guaranteed by our proven cardamatic suspension and a highly flexible headband that ensures a perfect fit for hours of listening. The professional-grade spiral cable offers flexibility and prevents tangles, making the GMP 250 as practical as it is sonically impressive.

Authentic German Manufacturing

Every pair of GMP 250 headphones is proudly designed, engineered, and assembled by our team in our own factory in Obrigheim, Germany. This commitment to in-house manufacturing ensures we meet the absolute highest standards of quality, precision, and durability.
