. Function and specification regarding professional
usage
-1 Lightweight magnesium alloy housing
In professional studios, it is common for headphones to be put
to use for long periods of time. That is why comfort is extremely
important from the standpoint of reducing fatigue. And the
lightweight design plays a large role in providing that sort of
comfort.
The housing component forms the largest part of the headphones.
Here we used magnesium alloy, which is known for having a high
specific strength (strength to weight ratio) among usable metals at
industry level. This allowed us to make the housing thinner and
achieve a lightweight headphone body that is approximately
10 %* lighter than before. Moreover, the magnesium housing
prevents unnecessary vibration for smooth bass response and
clear mid-high range sound.
-2 OFC voice coil
For the voice coil, high grade OFC Litz cord is wrapped around the craft bobbins. This lightens the voice
coil weight for high sound quality while simultaneously improving durability and providing a power
handling capacity of 4,000 mW. This prevents problems such as damage caused by typically unexpected
large scale input events that occur frequently in professional studios.
-3 Detachable cord
The cord is detachable, and we have included both a 3 m and 1.2 m cord. You can select the cord for the
situation, such as the 3 m cord for studio work where length is essential, or the 1.2 m cord for portable
operation, for example, combined with a camera-recorder for location work.
