WHAT WE TEST

THX engineers complete hundreds of different scientifically-formulated tests to ensure the highest audio standards possible. Key tests in the THX Certified Headphone program are as follows:

Razer Hammerhead True Wireless Pro THX Testing

FREQUENCY RESPONSE

Headphones are tested to ensure a well-balanced frequency response with minimal channel imbalance. This allows you to hear all the details in high-resolution tracks, ensures dialog in movies, and vocals in music are clear while maintaining deep, impactful bass output that doesn’t overpower the listening experience.

DISTORTION VS OUTPUT

The best sound comes from sufficient sensitivity to achieve a premium level of audio output while maintaining minimal distortion at the required sound pressure level. This means your headphones can easily playback content at increased volumes without introducing unwanted noise.

ISOLATION

Attenuation of external noise is evaluated to gauge the isolation provided by the headphones, making sure they seal in your audio and block out other sounds.
