Chord Electronics Mojo 2 Portable DAC and Headphone Amplifier (4.4mm)

The Chord Electronics Mojo 2 is a portable DAC and headphone amplifier built for listeners who want serious desktop-grade digital performance in a compact, travel-friendly format. Designed and built in Britain, Mojo 2 combines Chord’s long-standing FPGA-based DAC architecture with a powerful headphone stage, broad digital connectivity, and a feature set that makes it as useful on a desk as it is in a bag.

What makes Mojo 2 different is not just that it is small. It is that it delivers real high-end digital audio performance in a portable chassis without treating portability like an excuse for compromise. It supports high-resolution PCM and DSD playback, offers Chord’s transparent UHD DSP for headphone matching and tonal adjustment, and now includes both 3.5 mm and 4.4 mm headphone outputs for better compatibility with today’s cables and terminations.

What’s New in the Updated Mojo 2

The current Mojo 2 keeps the core strengths that made it such an easy recommendation, but adds a few meaningful hardware and usability upgrades. One of the original dual 3.5 mm outputs has now been replaced with a 4.4 mm output, while the 3.5 mm output remains in place. That gives Mojo 2 broader compatibility with modern headphone cables and balanced-style terminations without losing support for standard 3.5 mm plugs.

The updated version also adds independent volume and DSP memory for the 3.5 mm and 4.4 mm outputs. In practical use, that means you can move between two different headphones and have Mojo 2 remember the settings you last used for each one. Chord has also made the USB-C input user-switchable for both data and charging, which makes day-to-day use more convenient whether Mojo 2 is part of a desktop setup or a portable chain.

Why Mojo 2 Still Stands Out

Mojo 2 is built around Chord’s custom-coded FPGA platform rather than an off-the-shelf DAC chip approach. That matters because it gives Chord more control over filtering, timing, noise shaping, and overall digital reconstruction. The result is a portable DAC/amp that sounds clean, dynamic, and highly resolving, with the kind of precision and separation that helps better headphones show what they are really capable of.

It is also unusually flexible for a product of this size. Mojo 2 supports USB-C, Micro-USB, optical, and coaxial digital inputs, works with phones, tablets, laptops, and transports, and can be paired with Chord’s Poly streamer for wireless playback. Whether you use it as a compact desktop DAC/amp, a transportable source for travel, or the center of a small high-end headphone rig, Mojo 2 covers more use cases than most portable DACs in its class.

UHD DSP and Daily Usability

One of Mojo 2’s biggest advantages is its UHD DSP. This is not a throwaway tone control. It is a transparent digital signal processing system designed to let you fine-tune the sound for different headphones, different recordings, and different preferences without the usual penalty in clarity. Combined with the built-in menu system, Mojo 2 gives you direct access to tone controls, crossfeed, mute, button lock, and charging behavior in a way that feels genuinely useful rather than overcomplicated.

Chord also improved battery management, charging efficiency, and desktop usability. Mojo 2 supports Intelligent Desktop Mode for long-term plugged-in use, and its battery system is designed to improve charging efficiency while preserving long-term reliability. That makes it a better fit for users who want one device that can move between portable and home listening without needing to change habits or compromise on sound quality.
