A design that attracts attention and makes a statement. With balanced high-fidelity sound. Natural voices and rich details give your style a voice. For confident listening, every day. Headphone (1) ensures efficient sound transmission and deep, rich bass thanks to the customised 40 mm speaker and the highly linear earpiece design with PU membrane. The PU cushion material is more effective than conventional materials such as PET and ensures deeper, richer tones in the lower frequency range. With a width of 8.9 mm, it exceeds industry standards, minimises distortion and stabilises the driver so that precise vibrations are possible. The cone, rim and dome of the speaker are nickel-plated. This ensures clearer highs and at the same time rich, powerful bass - so you can experience more layers of sound. The added rigidity of the cone reduces distortion and brings out the subtle sound textures in every track. The evenly structured dome ensures a natural, clear sound. This means less distortion and clear sound even at high volumes. The sound of Headphone (1) has been tuned in collaboration with KEF - a long-established British audio brand with over 60 years of expertise. Using KEF's advanced measurement and analysis tools and in-depth expertise, a sound profile has been created that reproduces music as the artists intended. KEF stands for precise tuning and natural balance, providing a level of refinement that enhances every listening experience. The result is an immersive sound that is detailed, vibrant and authentic in every genre.
