Know before you buy
The Cobalt headphones feature a bright sound signature characterized by high clarity and tight, controlled bass. Thanks to the carbon-coated diaphragms, they are designed to deliver a precise, high-resolution listening experience.
Yes, they are built for comfort with a lightweight design and angled Elite Mesh Sheepskin earpads. The wide earholes also help reduce pressure while improving the overall acoustic imaging.
With an impedance of 16 ohms and a sensitivity of 101 dB, these headphones are relatively easy to drive. You should be able to achieve good volume levels directly from most smartphones, laptops, or portable digital audio players.
As a sealed, over-ear design, the Cobalt provides passive noise isolation by physically blocking out ambient sound. While it does not feature active noise cancellation, the tight seal of the earpads is effective at minimizing external distractions.
The headphones use a standard 3.5mm wired connection, making them compatible with most audio sources. A 3.5mm to 6.3mm adapter is included in the box, allowing you to easily connect them to home stereo systems or professional audio interfaces.
