■Product Description■
Founded over 80 years ago, Ashida Acoustic Co., Ltd. has been making the highest quality headphones to meet the high demands of musicians and engineers. Now, they have developed these high quality headphones for general users, with a focus on domestic production.

In 1957, we developed the ST-1 as a pair of headphones for professional use, and have since sold a variety of headphones to many studios, broadcasting stations, etc. Among these, we have now commercialized the long-popular "ST-90" as the "ST-90-05" for music use.

Equipped with a high-quality Φ40 driver unit developed by utilizing the know-how gained from designing numerous top-class headphones. Equipped with a diaphragm made of engineering plastic film with high compliance, light weight, and excellent tan δ, and a powerful magnetic circuit with a theoretical value of 1 Tesla.

Even though these are small on-ear headphones, they deliver rich, powerful sound quality across the entire range.

Weighing just 110g, it is quite light for headphones, making it ideal for mobile use. In addition, it is highly durable and has a proven track record in professional use.

It follows a timeless retro-modern design.
The headband has a simple structure but can be adjusted smoothly.
