AIYA

• Position: Entry-level line, designed for affordability and compactness.  
• Description: Features a 21mm ultra nano composite planar magnetic diaphragm that delivers clear and balanced sound in a small, portable design. Compared to the over-ear models in the lineup, it suits those with modest budgets and small room or on-the-go needs, while models like Aiva 2, Apollo, AIVA, and Peacock deliver larger drivers and more advanced features for expanded functionality.

Aiva 2  

• Position: Budget planar magnetic headphone offering balanced performance for everyday listening.  
• Description: Uses an ultra-thin high-strength diaphragm that clearly reproduces mids, highs, and a wide sound stage. When compared to the in-ear AIYA and other over-ear options like Apollo, AIVA, and the flagship Peacock, it meets practical functionality and moderate budget tolerance without extra advanced features.

Apollo 

• Position: Entry-level open-back over-ear headphone that balances style with performance.  
• Description: Features a 68mm diaphragm paired with a unique wood earcup and steel mesh design that provides natural sound reproduction and comfortable wear. In comparison to models such as Aiva 2 and AIVA, it offers a traditional design, though it lacks some of the advanced driver and material refinements seen in the higher-tier Peacock.

AIVA

• Position: Mid-range open-back over-ear headphone focused on detailed sound reproduction.  
• Description: Includes a larger 97×76mm driver and refined wood components that help deliver natural, clear vocals and deep bass, setting it apart in clarity and performance. Relative to the simpler designs of Apollo and Aiva 2, AIVA targets users willing to invest a bit more for improved detail and a fuller sound stage.

Peacock 

• Position: High-end open-back over-ear headphone positioned as the flagship with advanced design and performance.  
• Description: Features an 88mm ultra-thin composite diaphragm that extends high frequencies and offers a wide, natural sound stage, backed by high-end materials and meticulous craftsmanship. Compared to every other product in the lineup—from the in-ear AIYA to the entry-level Apollo—Peacock is ideal for users with a higher budget looking for top performance, advanced technology, and functionality suited for larger spaces.
