Beep Audio / GOKU Closed-type Hybrid Earphones

"GOKU" is a closed-type hybrid earphone with 2DD+4BA that allows you to enjoy the difference in sound quality in a flexible manner.

■The core of the "Goku" earphones: an evolved hybrid architecture
・The foundation of the acoustic performance of "Goku" is the advanced driver configuration of the proprietary "2DD+4BA". This design is packed with technological breakthroughs such as:

1. Dual Dynamic Driver System
-Main 10mm driver: Responsible for the mid-low range, building a foundation for rich sound
-Sub 6mm driver: Designed specifically for ultra-low range, clearly reproduces deep bass below 30Hz
-Special magnetic circuit achieves 150% vibration efficiency compared to conventional models

2. Quad balanced armature arrangement
-2 BAs dedicated to mid-high range
-2 BAs dedicated to ultra-high range: Extends without distortion to ultra-high range above 10kHz
-Uses "seamless crossover technology" that optimizes phase matching between each BA

3. Acoustic chamber design
-Precise internal structure created with 3D printing technology
-Independent acoustic paths dedicated to each driver

■Sound quality characteristics with standard cable (Yongse Ruyi Rod): Ideal for listening to calm music
・When using the included standard cable Ruyi Rod, the cable has a resistance component, so "Goku" exhibits calm and warm sound characteristics. The mid-high range is delicately reproduced, and the nuances of vocals and acoustic guitars are especially beautifully expressed. The bass has a soft, enveloping texture, and is designed to prevent ear fatigue even with long listening sessions.

■Sound quality characteristics with optional cable (Daruma Audio X-Stage): Immersive experience with a sense of realism
・When you replace it with the optional Daruma Audio cable "X-Stage", "Goku" shows a completely different character. The bass is tightened and the sharpness of the beat is greatly improved. The high range is expanded, and the sparkle of the cymbals and the vibrato of the vocals emerge more clearly. In this mode, you can fully enjoy high-energy music. The sound field is greatly expanded, recreating the open feeling of a festival venue or a stadium live. This sound profile is ideal for exercising or when you want to lift your spirits.
