BulletPoint1 : 3+1 is more than 4: In order not to suppress the performance of 33518 BA, the conventional 3-way tuning scheme is unable to adapt to its excellent high frequency.Therefore, through the advanced tuning technology, the overall 3-way frequency is completed,and then a special process,so that the high-frequency extension performance and the avoidance of squealing sound are considered.After being finely tuned,the overall sound is more comfortable and more accessible, with moderate energy distribution.
BulletPoint2 : Freedom from constraints, comfort, and reliability: The shell is made from a mature mold that integrates ergonomics and acoustics, which provides good support when wearing and refuses the discomfort caused by wearing it for a long time. The shell printed by high-precision 3D printing technology ensures that the internal drivers of the cavity are placed in a consistent environment, reducing deviation or sound field deformation caused by internal errors.
BulletPoint3 : Frequency response: Appropriate impedance can effectively avoid the turbidity of the sound caused by the front-end background noise. Aviation maintains high sensitivity of 118db in the case of 39ohm, which allows it to avoid background noise to a certain extent and also ensures the earphones' complete performance. Aviation adopts a 0.78mm 2pin interchangeable cable design, making it easy to play and enjoy freedom.
BulletPoint4 : Aviation is equipped with a 4-core Coaxial + Litz combination structure of 5N OCC detachable plug cable. In the case of the same wire base, cables with this structure are better than other others with ordinary structures in terms of shielding performance and conduction performance. For the listening experience, the sound is purer and smoother. 5N OCC wire further reduces the sound signal attenuation, strengthens the sound signal transmission, retains more sound details, and restores the sound.
BulletPoint5 : Eartips: Equipped with ear tips with different listening experiences, users can choose freely in terms of sound and wearing. Balanced Eartips: Sound is balanced and cohesive, suitable for users with long ear canals. Vocal Eartips: The human voice is sweet and close to the ear, suitable for users with short ear canals.
