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.

XX Audio Cable for Professional Audio

The X5h comes with an audiophile grade silver-coated OFC cable to link your professional audio equipment such as media players and headphone amplifiers for optimum sound quality.

XX Remote Cable for Mobile Devices

​The X5h comes with a remote cable with inline microphone to allow you to make calls and select tracks on your mobile devices. A superior MEMS microphone delivers incredibly clear voice quality.

(Note: Please note that some mobile devices may not fully support the remote because of different Apps or operation systems.)

Switch between Wired and Wireless

The Bluetooth Cable can turn all MAS headphones into Bluetooth headsets when it is connected. When the Bluetooth cable runs out of battery, you can disconnect it from the headphones for charging separately, and can keep enjoying the music seamlessly by connecting the headphones with other MAS cables.
