Overview The Final E4000 is a high-resolution, in-ear monitor (IEM) designed with the latest acoustic engineering and psychoacoustic research. It delivers pure, detailed sound across all frequencies, creating a realistic and immersive listening experience. Key Features 1. Smooth Frequency Response for High Resolution Unlike traditional designs that boost specific peaks, E4000 uses a smooth frequency curve, avoiding masking effects between frequency ranges. Provides clear, natural, and delicate sound, especially in comparison to E3000 and E2000 models. Lower initial sound pressure ensures long listening comfort and lets the user gradually explore its nuanced audio. 2. Acoustic Chamber for Controlled Bass The internal acoustic chamber, positioned behind the driver, shapes mid-to-low frequency characteristics. L-shaped acoustic channel balances bass weight and clarity for a natural sound. 3. MMCX Connector + Original OFC Cable High-precision MMCX connector developed by S’NEXT. Flexible and soft cable coating reduces microphonics and allows comfortable use with ear hooks. 4. Swing-Fit Earpiece Mechanism Earpieces can pivot to match the ear canal angle, preventing deformation and delivering direct sound to the eardrum. Ensures a secure, personalized fit for various ear shapes. 5. High-Rigidity Aluminum Housing Machined aluminum with anodized finish provides durable, vibration-free support for the driver. Elegant, minimalist design aligns with the high-resolution sound quality.
