HiFiGo AFUL Performer 5+2 Performer 7 IEM, 2DD+4BA+1 Micro-Planar Unit In-Ear Monitor Earphones, 3D Printed Acoustic Tube Structure (4.4mm)

Faceplate Design Inspiration: Inspired by the serene elegance of Eastern aesthetics found in the tranquil gardens of Suzhou, the captivating beauty of the faceplate design transforms your listening experience. Travel down a secluded path to be immersed in a Zen room where a harmonious blend of flowers and trees evokes a sense of peace and tranquility. Wide Frequency Response Range: A wide frequency response range enhances the accuracy and realism of musical instrument reproduction, effectively capturing both the dominant fundamental frequencies and overtones. Many earphones on the market can only handle the dominant frequency range and are inadequate at reproducing overtones due to their limited frequency response. Easy to drive: Thanks to its advanced technology, the Performer 5+2 is highly efficient and easy to drive. Its full potential is realized with a high-quality source, but it also sounds great when paired with a portable dongle or Bluetooth DAC/amp. Superior Bass and Treble: With the addition of two dynamic drivers and a micro-planar unit, AFUL's unique acoustic and circuit design ensures that bass texture, depth, treble resolution, and instrument separation are all on the level. Advanced Acoustic Engineering: By integrating a precise and complex 3D acoustic structure with an RLC network crossover, AFUL has significantly improved acoustic performance. This advanced modeling and design of [acoustic structure - speaker - RLC network] has resulted in a significant improvement in sound quality. Improved Sound Precision: Dual dynamic drivers and a 3D-printed Y-shaped structure enhance low frequencies, significantly improving the elasticity and density of bass. The addition of a micro-planar driver at high frequencies significantly improves treble extension and enhances overall sound precision. Further refinements to the acoustic structure and crossover circuitry improve overall sound consistency and texture.
