6mm Micro Dynamic Driver Unit

Bullet-shaped Design - Fashionable and Elegant
Princess Changle exudes a gentle and approachable temperament, making it adored by all. The avant-garde bullet-shaped design accentuates Princess Changle's charm, complemented by intricately engraved auspicious cloud patterns, showcasing extraordinary elegance and approachability.

Semi-Open Sound Tuning - Authentic Sound Reproduction
Princess Changle features a semi-open design for the rear cavity, allowing better adjustment of airflow between the cavity and the eardrum. This relieves pressure in the ears, prevents the formation of a closed space that could deform the diaphragm, and results in transparent and open sound, faithfully reproducing the most authentic audio.
