Descriptions:

> The HA-SX12/HD is equipped with a diaphragm manufactured by Giftoku Co., Ltd., made from Mitsumata, a material traditionally used in the production of Japanese paper for its strong and resilient fibers. The driver features a self-developed free edge design and a magnetic circuit with a theoretical magnetic flux density of 1 Tesla, enabling powerful and precise sound reproduction.

> Both the internal wiring and the detachable cable use high-quality oxygen-free copper (OFC) cords manufactured by Hisago Denzai Co., Ltd. This construction delivers a highly realistic listening experience with rich bass, natural mid and high frequencies, and a well-defined midrange presence.

> Free Edge Driver Technology
  > The free edge driver structure supports the outer edge of the diaphragm with a material different from the diaphragm itself.

  > Conventional headphones typically use a fixed edge diaphragm, where both the diaphragm and its surrounding edge are made from the same material. In contrast, the free edge design allows each component to possess optimal physical properties, resulting in improved diaphragm movement and deeper, more natural bass reproduction.

> Design
  > Like the hugely popular ST-90-05, the HA-SX12/HD features ASHIDAVOX’s signature timeless retro-modern design. Its soft color palette and rounded shape make it approachable and comfortable to use, including for female users. The embossed housing adds a refined, luxurious aesthetic.

Comfort and Adjustability
  > The headband features a simple yet effective structure and can be adjusted smoothly to ensure a comfortable fit.

  > Note: Due to packaging, the cable may leave temporary marks on the headband when first opened. These marks will naturally disappear over time. Please use the product with confidence.

> Sound Quality
  > Compared to the HA-ST12, the HA-SX12/HD offers a wider frequency bandwidth and significantly improved clarity. The low frequencies are extended to provide greater depth, while the midrange is enhanced to bring vocals and central instruments in the mid-to-high range closer and more forward. This tuning increases the overall power, realism, and presence of both low and mid frequencies.
