Using industry standards and a proprietary testing methodology, THX engineers evaluate and certify the audio and visual fidelity of consumer electronics to ensure they deliver the optimal entertainment experience.

Optimal Performance

THX works with partners from the ground up, so that certified products deliver professional quality audio-visual experiences right out of the box.

Superior Quality

A lot of products don’t meet our standards. We only certify the very best products with uncompromised quality, performance and consistency.

Seamless Integration

In a perfect world, all products would meet our standards. Until then, we ensure that THX certified devices play well with lower performing devices and components.

Tested Inside-Out

THX laboratories currently apply over 400 separate tests to ensure sound and picture quality are fully preserved. Nobody tests as rigorously as we do.
