Tuning Idea- Gentleness originates from the comfort of sound

Ms. Azuna Riko says:

Since experiencing sudden sensorineural hearing loss, I've become somewhat sensitive to sharp or piercing high frequencies. Therefore, I prefer sound with fuller and richer bass.

My ideal earphones should have a smooth and mellow overall tone, with clear and expressive vocals, while remaining comfortable for extended listening sessions without causing ear fatigue.

Based on Azuna Riko's ideas, Melody Wings acoustic engineers conducted multiple rounds of communication and tuning with the Uranus, ultimately completing the sound tuning.

Unit Configuration-4-way & 4-unit design for a "natural" listening experience

Uranus features 4 completely different units: bone conduction, dynamic, balanced armature and piezoelectric, paired with a precise 4-way acoustic crossover. The 4-way circuit precisely distributes the full-range signal to the corresponding unit, avoiding frequency overlap interference and allowing each type of unit to fully utilize its acoustic advantages. The transitions between drivers are smooth and natural, reducing phase distortion.

• Extreme Low Frequency: 10mm bone conduction unit provides a full and spacious low-frequency foundation, increasing the sonic atmosphere and giving the low frequencies a warm thickness without being boomy or bloated.
  
  
• Mid-Low Frequency: 10mm beryllium-plated dynamic driver (N52 magnet dual-cavity structure) drives air, bringing a natural and relaxed foundation texture, laying the groundwork for vocals and instruments.
  
  
• Mid-High Frequency: Balanced armature unit ensures vocal density and clear vocal imaging, reproducing the breath and emotional details in singing.
  
  
• Ultra-high frequencies: Piezoelectric driverextend the ultra-high frequencies that are difficult for ordinary drivers to reach, bringing out overtones and a sense of airiness, while controlling high-frequency harshness and avoiding sharpness and piercing.

The 4 drivers work together in a 4-way crossover architecture to create a rich bass, warm vocals and clear, smooth high frequencies, achieving a relaxed and natural "breathing" listening experience.
