TRUTHEAR Portable USB-C DAC headphone amplifier KEYX

The TRUTHEAR KEYX is a compact USB-C DAC and headphone amplifier that improves audio quality from a smartphone, computer or other compatible device without requiring additional components. Its Cirrus Logic CS43131 chip handles signal conversion with low distortion and a high signal-to-noise ratio. The L-shaped housing connects the 3.5 mm jack directly to the circuit board, eliminating the short cable found in many adapters and resulting in a clean, ergonomic design. The integrated layout also helps shield the unit from interference from wireless and communication devices nearby.

The KEYX works with a wide range of multimedia and streaming platforms and supports microphones, so it suits both music listening and voice calls. Online DSP support lets you adjust the sound to your preferences, and the EQTOOL.COM platform offers more precise tuning, best used on a computer. The package includes the KEYX DAC, a key ring and a user manual.
