ddHiFi Surface Hybrid In-Ear Earphones (Model: E14D)

1DD + 4BA Drivers | Unique 2D Aesthetic | 4.4mm Balanced Cable

Description

Meet the ddHiFi Surface (E14D), a hybrid driver in-ear monitor that masterfully blends innovative aesthetics with sophisticated acoustic engineering. The unique "Come to the Surface" design philosophy creates a visually striking flattened, two-dimensional appearance when worn, simplifying complexity. Internally, it boasts a powerful 1 Dynamic Driver + 4 Balanced Armature configuration arranged in a physical 3-way crossover, utilizing optimized driver modules and ddHiFi's distinct tuning philosophy. Built with meticulous craftsmanship, including a reinforced socket structure and a 3D printed resin shell, the Surface delivers a balanced, engaging sound signature complemented by a premium ddHiFi BC120s 4.4mm balanced cable as standard.

Features

  • Unique "Surface" Aesthetic: Features a distinctive flattened design that transitions from 3D form to a 2D visual plane when worn, offering a unique look.
  • Hybrid Driver Configuration: Combines one dynamic driver for robust lows with four balanced armature drivers (for mids and highs) in a physical 3-way crossover structure for detailed and balanced sound.
  • Optimized Tuning: Leverages driver unit modules optimized from previous MOONDROP models integrated with ddHiFi's specific tuning philosophy for a fresh, balanced, and enjoyable auditory experience with solid mid-bass.
  • Robust Structural Design: Features a reinforced 0.78mm 2-pin socket, secured not just by soldering but with a CNC-machined aluminum reinforcement piece between the cavity and cover plate for enhanced durability.
  • Meticulous Craftsmanship: Employs a "simplifying complexity" approach with neat internal wiring and component layout on a specially developed crossover board, ensuring consistency and aesthetic appeal.
  • Advanced Crossover & Wiring: Utilizes a specially developed circuit board resulting from extensive comparisons and user feedback. Wiring converges at the back of the board to minimize electromagnetic interference.
  • Premium 3D Printed Shell: The main shell and front chamber are crafted using high-precision 3D printing with imported medical-grade resin, incorporating physical filtering sound conduits.
  • Standard Upgraded Cable: Includes the high-quality ddHiFi BC120s cable featuring a 4.4mm balanced plug, 0.78mm pins, high-purity silver-plated OFC Litz conductors, and robust shielding.
