The chip reduces three types of distortion by up to 40dB and maximizes output power for more dynamic range and sound pressure level (SPL).

THX explains that the AAA-78 makes the Onyx just as powerful as a desktop DAC or amplifier setup, but it's much smaller. Not only is this the highest-powered mobile THX Achromatic Audio Amplifier configuration, but the company says this is the first portable DAC/amp to use the component. Inside, the Onyx has a THX AAA-78 amplifier chip. The device comes with a USB-C to USB-A adapter, so if your laptop isn't equipped with the former, you can still use it with the latter. On the front, a trio of LEDs indicate the quality of the audio you're listening to with options for standard, high resolution, Direct Stream Digital (DSD) and Master Quality Authenticated (MQA). The company suggests using it to keep your headphone cable wound to keep everything tidy. The USB-C plug is magnetic, looping back around and attaching to the main body of the audio accessory when not in use. Like much of the competition, the Onyx is a USB dongle with a cord on one end and a headphone jack on the other. With its first consumer hardware, the Onyx, the company adds a tiny, high-powered alternative to traditional DAC amplifiers. There are a number of options already on the market, but today immersive audio and video tech company THX is adding its name to the list. To achieve the ultimate audio on the go, you'll likely need a high-res player or a portable digital-to-analog-converter (DAC) and amp combo.

That can be especially true if you prefer a set of wired cans over anything wireless. When it comes to mobile audio, sometimes the sound your phone and headphones muster just isn't enough.
