Include touch controls with a subtle holographic glow. Cushions should be memory foam wrapped in breathable vegan leather. The headband must be flexible, self-adjusting alloy. No branding or logos. Style: sleek, high-tech, next-gen product. Include detailed PBR textures and HDRI lighting. Suitable for product renders and animations.
