Know before you buy
The carbon-coated diaphragm provides increased rigidity and responsiveness, which helps the driver move with greater precision. This results in a cleaner, more articulate sound profile with improved transient response compared to standard dynamic drivers.
Unlike many closed-back designs that can sound congested, the Cobalt offers a surprisingly multidimensional soundstage. It prioritizes instrument separation and a balanced, delicate presentation over heavy, overwhelming bass.
The Fenestrated Sheepskin pads are designed to provide a more breathable, controlled sound with a slightly tighter seal, while the Elite Velour pads offer a softer, more plush feel that can slightly alter the acoustic resonance for a different listening experience.
Yes, the combination of a thick, padded headband and high-quality earpads is designed for extended comfort. The closed-back design also provides passive noise isolation, which helps maintain focus in various environments.
Because of their precise mids and articulate highs, these headphones excel with acoustic genres like classical, folk, and jazz. They are ideal for listeners who prioritize vocal clarity and the nuanced texture of stringed instruments.
While these headphones can be driven by many standard devices, they are designed to perform at their best with a dedicated amplifier. Using a quality DAC or amp will help you fully realize the potential of the carbon-coated driver and the detailed soundstage.
