Truthear Nova 1DD + 4BA Hybrid Driver In Ear Monitor Earphone

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.

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 waveguides, therefore, the objective index of NOVA closer to the design goal based 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 results in a warm, soft, clear and natural sound thanks to the brand-new overall system design of lowering the Q value.

Equipped with Multiple Sets of Ear-tips

Apart from the classic thin-diameter ear-tips, NOVA also comes with short double-flange ear-tips, long double-flange ear-tips and foam ear-tips with multiple limiters.

High-quality Cable Rich Expansibility

NOVA has a versatile 0.78 2Pin interface, with the ear hook to correct
the length and angle, and the newly designed single crystal copper wire (4 strands with 112 cores, 448 cores in total) with wire skin material.
