## Description

★ U-Series 4 Driver Custom IEM balanced / armature type (BA type) ● In addition to the driver for the mid-to-high range, two powerful subwoofers of proprietary designs with patents create a powerful low range U4. Such sounds were possible only with large and bulky overhead type headphones, but U4 can fully reproduce the impact of richness and deep bass because of its advanced IEM design. U4 has been given the best tuning for drummers, percussionists, bassists and so on. U4 has adopted revolutionary apex technology. Apex (air pressure exchange) is a technology to eliminate air pressure generated by a small speaker in the sealed space of the ear canal. Apex delivers an excellent listening experience that could not be realized with traditional IEM. ◆ Apex Technology ● When the ear canal is closed with a small speaker, the speaker generates air pressure (sound pressure). This air pressure causes fatigue of the ear, and furthermore it causes a risk of leading to hearing loss by excessively burdening the tympanic membrane. Apex? Technology (Air Pressure Exchange) is a technology developed to reduce the risk of hearing loss, and alleviates air pressure generated by a small speaker in a hermetically sealed space inside the ear canal through a module. Apex technology is technology that keeps your hearing by suppressing the fatigue of your ears and improves sound quality dramatically. ◆ 3D Fit Technology ● 64 AUDIO has created a new manufacturing process where the shell fits into individual individual ear molds. Currently, it adopts a new manufacturing process of custom IEM called "3D fit technology". ◆ 64 AUDIO Personalized Case ● It is a custom IEM hard case prepared custom-made for 64 AUDIO (1964 EARS) custom IEM. It is designed so that it can be stored and carried easily not only to earphones but also to parts of accessories.
