TRUTHEAR NOVA 1DD+4BA In-Ear Headphones (NOVA)...

["Polyurethane suspension compound liquid crystal dome membrane and dynamic driver with N52 magnet with two cavities. Featuring the DLP 3D printed cavity commonly used in high-end multi-driver and custom headphones. Comes with braided cable with multi-core single crystal copper for excellent sound quality.","Efficient driver configuration Nova is a 1DD+4BA in-ear headphone with 3-way crossover compound structure. Compared to HEXA, the original design intent is to further enhance high-frequency performance while maintaining a reasonable and efficient configuration, and also striving to provide users with a mature headphone with a hybrid 3-way crossover structure at a reasonable price. Nova uses a specialized 10mm diameter dynamic driver to handle the bass.","Accurate hybrid frequency division. The acoustic waveguide structure with filter function is achieved through high-precision DLP 3D printing technology and RC frequency division through accurate calculation, allowing the five drivers to function well under various corresponding acoustic waveguides, therefore Nova's target index is closer to the design goal based on HEXA.","Outstanding measurements. Nova has slightly less bass boost than the HARMAN IE 2019 curve and is close to the high-frequency amplitude response of HARMAN OE 2013 with high HRTF properties, resulting in a warm, soft, clear, and natural sound due to the brand-new system design aimed at lowering the Q value.","Next generation DLP 3D printing technology. HeyGears' DLP 3D printed cavity is equipped with its own medical-grade high-transparency resin. It can realize complex sensitive acoustic waveguide structures while ensuring printing accuracy and efficiency. At the same time, it handles the lightweight cavity well and ensures that skin-friendly and reliable cavity materials are used. A brand-new, precise, reliable ID design."]
