“Next was a demo of Dirac Bass, which really amazed me. I was first shown a basic $40 speaker from IKEA. Sound quality was acceptable, with a flat and even sound profile, that had no real distinction between highs, mids, and lows. Once the speaker utilized Dirac Bass, you could really hear the difference. This went beyond using an equalizer preset that was set to favor the lows, which would typically result in the highs and mids being drowned out. Dirac Bass gave you a deep sounding low while keeping the other tones intact, with no distortion and overall evenness.”
The OnePus 6 utiliizes two Dirac mobile audio optimization solutions. Dirac HD Sound improves the headphone audio of the OnePlus earphones while Dirac Power Sound optimizes the smartphone audio of the device's built-in speakers.

But as mobile display technology matures, manufacturers are looking to other areas to distinguish themselves, such as sound.
