High Resolution Drivers

The new 40mm dynamic drivers with specially designed diaphragms and super lightweight aluminum-copper voice coils produce crisp highs, clear mids and punchy basses. Equipped with proprietary semi-open back design, the X5h not only sounds naturally like open back headphones but also maintains solid low frequency energy like closed back headphones. The X5h featuring high fidelity and extremely wide frequency response from 5Hz to 50,000Hz is Hi-Res Audio certified by the Japan Audio Society. 

Core Array Technology™

The Core Array Technology ™ integrates precision coaxial acoustic design with high end speaker sound-tuning technique to control the sound wave energy effectively, minimize distortion and produce spacious soundstage. 

​Detachable Cable Design

The X5h with detachable cable design through MMCX connectors allows you to upgrade or swap the headphone cables. You can even turn the X5h into a Bluetooth headset with the optional MAS XX Bluetooth Cable or turn the X5h into a 3D surround gaming headset with the optional MAS XX USB-C Headphone Cable.
