[Product Description]

● Power and delicacy with 50mm neodymium drivers

Equipped with large 50mm dynamic drivers. It brings out sound information clearly from the low range to the high range, allowing you to enjoy even the subtle nuances built into the music. With classical music and large-scale orchestral pieces, it makes the sense of expansiveness and dynamic presence easier to feel, offering the kind of enjoyment that makes you want to listen to familiar tracks all over again.

● Bright, clear sound with excellent sonic visibility

This model is characterized by a “bright and clear sound.” Even in tracks where multiple instruments overlap, it makes it easier to perceive each sound’s presence, making it suitable not only for music listening but also for tasks such as recording, tracking, and mixing where accurate sound monitoring is important.

● Natural sound expansion unique to a semi-open design

Another major highlight is the semi-open construction, which differs from closed-back models. It reduces the sensation of sound being trapped only inside your head, letting you enjoy a more expansive and open sound. It pairs especially well with classical music and tracks with a live feel, or any source where you want to enjoy spacious sound expression.

● Wide frequency response from 10Hz to 30,000Hz

The playback frequency range is 10Hz to 30,000Hz. With a wide-range design that covers much of the human hearing spectrum, you can enjoy the full breadth of audio information in a source, from rich low frequencies to delicate high-frequency detail.

● Self-adjusting headband designed for long listening sessions

When worn, the self-adjusting headband conforms to the shape of your head. In addition, it uses ergonomically designed ear pads and a lightweight build, aiming to provide comfortable wear for long listening sessions and extended work periods.

● Single-sided straight cable for easy handling

The cable is a straight type with a single-sided design that extends from only one side. This makes it easier to manage around a desk or in a recording environment, since the cable is less likely to split to both sides. In addition to the 3.5mm stereo mini plug, it also supports an adapter that converts from 3.5mm to 6.3mm.

● Simple black color that blends into a wide range of environments

With a calm design centered on black, it fits naturally into music production desks as well as home audio setups. It has been finished in a simple, practical style that is typical of monitor headphones focused on functionality.
