Description

TRUTHEAR KEYX CS43131 Portable DAC & AMP

Experience true high-resolution audio anywhere with the TRUTHEAR KEYX CS43131 Portable DAC & AMP. Designed for audiophiles and music enthusiasts, the KEYX combines the acclaimed Cirrus Logic CS43131 DAC chipset with an innovative L-shaped cable-free design, delivering exceptional sound quality, superior portability, and everyday convenience.

Unlike conventional USB DAC dongles that use a short cable between the USB connector and headphone output, the KEYX integrates the 3.5mm headphone jack directly into its CNC-machined aluminium body. This unique construction improves durability, reduces cable failures, minimizes radio frequency interference (RFI), and provides a cleaner, more reliable listening experience.

Powered by the high-performance Cirrus Logic CS43131 DAC and an advanced USB controller, the KEYX delivers outstanding measurements with low distortion, ultra-low noise, high dynamic range, and excellent signal-to-noise ratio. Whether you're streaming music, gaming, watching movies, or taking calls, the KEYX ensures detailed, dynamic, and natural sound reproduction.

Supporting PCM up to 384kHz/32-bit and Native DSD64 to DSD256, the KEYX unlocks the full potential of Hi-Res Audio from smartphones, tablets, laptops, and compatible USB-C devices.

The KEYX is also designed with modern users in mind. It fully supports microphones, inline controls, and DSP-equipped earphones, making it compatible with a wide range of IEMs, headphones, gaming headsets, and streaming applications.

To further enhance your listening experience, TRUTHEAR provides access to EQTOOL.COM, a professional browser-based equalization platform that allows users to create precise EQ profiles, manage presets in the cloud, and fine-tune their sound without installing additional software.

Whether you're upgrading your smartphone's audio output or looking for a compact high-performance DAC for daily use, the TRUTHEAR KEYX delivers premium sound in an incredibly portable package.
