qdc and Ayuto to release LINEAR MAGIC high-fidelity earplugs

Ayuto and the custom IEM brand qdc have announced the release of ‘LINEAR MAGIC’, a new type of earplug designed for live music events, clubs, and loud environments. Scheduled for release on September 18, the product is priced at 2,200 yen.

Developed using qdc’s sound adjustment technology and professional feedback, the earplugs feature a unique ‘memory foam acoustic filter’. This design aims to provide linear noise reduction of 25 to 30dB while maintaining high sound quality and a flat frequency response, allowing users to experience the energy of music without the harmful pressure.

The earplugs are constructed from medical-grade liquid silicone rubber (LSR) for comfort during long-term use. They feature a triple-flange shape to accommodate various ear sizes and weigh approximately 1g per side. The translucent black units are washable and include a neck strap to prevent loss, along with a portable storage case with a carabiner.
