Know before you buy
This proprietary design utilizes a powerful 1.5 Tesla magnetic flux density to drive the 50mm biodynamic diaphragm. This creates a highly efficient system that delivers exceptional sound accuracy, a vast dynamic range, and very low distortion.
Yes, the headphones feature a detachable cable system. This allows you to easily replace the included 7N OFC unbalanced cable or upgrade to optional balanced cables for different connectivity needs.
While the 25-ohm impedance makes them relatively easy to drive, these are high-end, open-style sounding closed-back headphones intended for audiophile or professional setups. To get the best performance, they are best paired with a dedicated high-quality headphone amplifier or DAC.
The TH-900 MK2 is designed with protein leather and foam earpads to provide a secure, comfortable fit. At 390 grams, they are substantial but well-balanced for extended use.
No, the TH-900 MK2 does not have active noise cancellation. They are a closed-back design, which provides some natural passive isolation, but they are primarily engineered for critical listening in quiet environments.
The Bordeaux Urushi lacquer is a traditional Japanese craft technique applied to the Japanese cherry birch wood earcups. Beyond its striking aesthetic, the lacquer contributes to the rigidity of the housing, which helps minimize unwanted resonance for cleaner sound reproduction.
