Our rigorous scientific measurements and listening tests have determined that a 44mm driver is the optimal size for this design. This size not only ensures professional performance but also facilitates significant air movement and prevents diaphragm 'wobbling'. The result is a headphone that delivers accurate, detailed sound, making it an excellent choice for both music enthusiasts and professionals. The ultra-stiff membrane of the Hi-X55 reduces unwanted resonance, further enhancing the sound quality. Moreover, the closed-back design of the Hi-X55 provides superior noise isolation. This feature allows you to immerse yourself in your music or audio content, effectively blocking out external noise. Comfort is also a key feature of the Hi-X55. These headphones are designed for extended use, ensuring that you can enjoy your favorite music or audio content in comfort.
