The wooden headbands are made from five layers of wood, with domestic birch and ash at the core. The surface is finished with carefully selected walnut or oak, resulting in a high-quality, stylish, and durable product. All wooden headbands are handcrafted in Finland, with each veneer individually chosen to ensure the best possible quality. The wood veneers we use are FSC-certified, guaranteeing responsible and sustainable sourcing of the materials.

All visible surfaces of the product are made of anodized black aluminum, not plastic. Aluminum is significantly more durable and long-lasting than plastic, and it retains its appearance better over years of use. The aluminum ear cups also perform better acoustically: their rigid structure isolates sound more effectively, improving the headphones’ noise-canceling performance compared to plastic enclosures. Additionally, the telescopic height adjustment mechanism of the headphones is made of zinc-coated metal, ensuring structural rigidity, wear resistance, and smooth movement throughout the product’s lifespan.

The sound quality of the headphones is tuned for the most natural and balanced listening experience possible. Professional expertise, high-quality components, and finely tuned EQ ensure that music and speech sound authentic and well-balanced. Additionally, active noise cancellation (ANC) provides a quiet listening experience in various environments—whether on public transport, in the office, or at home—allowing you to focus on music or calls without distractions.
