TRUTHEAR NOVA 1DD+4BA in-Ear Headphone (NOVA)…

• Adopting the polyurethane suspension composite liquid crystal dome diaphragm and dual-cavity internal magnetic circuit dynamic driver of N52 magnet. Utilizing the DLP-3D printed cavity commonly used in high-end multi-driver and custom earphone. Come with the braided cable with multi-core single-crystal copper. Present the excellent objective index.
• Efficient Driver-configuration. NOVA is a 1DD+4BA in-ear headphone with 3-way crossover composite structure. Compared with HEXA, the original design intention is to further improve the high-frequency performance while maintaining a reasonable and efficient configuration, and also strive to bring users a mature earphone with a hybrid 3-way crossover structure at a reasonable price. NOVA uses a 10mm diameter specialized dynamic driver to take charge of the bass.
• Accurate Hybrid Frequency Division. The acoustic waveguide structure with filtering function realized by the high-precision DLP-3D printed technology and the RC frequency division achieved by accurate calculated, which makes the five drivers perform well under different corresponding acoustic wave guides, therefore, the objective index of NOVA closer to the design goalbased on the HEXA.
• Excellent Measurements. NOVA has slightly less bass gain than HARMAN IE 2019 curve and is close to the high-frequency amplitude response of HARMAN OE 2013 with high HRTF characteristics, which resultsin a warm, soft, clear and natural sound thanks to the brand-newoverall system design of lowering the Q value.
• New GenerationDLP 3D Printing Technology. The DLP 3D printed cavity from HeyGears is equipped with its own medical-grade high-transparency resin. It can realize complex delicate acoustic waveguide structures while ensuring printing accuracy and efficiency, At the same time, it brings the lightweight cavity to fit well while making sure the skin-friendly and reliable cavity materials.A Brand New ConciseReliable ID Design.
