Chord Electronics Mojo 2
The British designed and built Mojo 2 is the most advanced portable DAC and headphone amplifier in the world today.
Winner of Best DAC (£300-£500) in the What Hi-Fi? Awards 2022, the Mojo 2 is entirely engineered around a powerful, custom-coded FPGA processor and benefits from several unique technologies.
Central to the new Mojo 2 is the world’s first lossless DSP, an advanced ‘digital tone control’ without any degradation in sound quality. The ‘UHD DSP’ gives Mojo 2 unrivalled compatibility with today’s wide-ranging headphones, plus unparalleled flexibility with partnering equipment.
A further key feature is the new menu system, navigated via the new (fourth) control sphere, bringing mute, crossfeed, button-lock and tone control adjustment.
Mojo 2 offers greatly improved battery management, with faster charging rates, a huge 75 % reduction in power loss, plus a 9 % capacity gain.
A new USB-C data input adds greater flexibility, transparency has been greatly boosted, thanks to an improved noise-shaper, lower distortion and greater neutrality, plus Mojo 2 can even be taken wireless with the Poly streamer/server.
Handmade in the UK with a robust CNC-milled aircraft grade aluminium chassis, Mojo 2 offers unrivalled performance, class-leading sound and peerless build quality.

Reference-class clarity in a pocketable box
The Chord Electronics Mojo 2 is a compact, feature-rich portable DAC/headphone amp that upgrades the original Mojo with a 104-bit FPGA, expanded WTA filter and a new lossless UHD DSP for four-band tone control and crossfeed. Reviewers note a marked jump in transparency, micro-detail and soundstage openness while retaining tight, textured bass and natural treble. What Hi‑Fi? and HiFi News highlight the improved resolution and dynamics; Enjoy The Music and StereoNET emphasise the practical gains—USB‑C, Poly compatibility, desktop bypass and solid aluminium build—making Mojo 2 ideal for discerning mobile listeners and desktop setups that demand laptop‑sized performance.
Pros
- Reference-level clarity and transparency with improved resolution and soundstage compared with the original Mojo.
- Powerful, low‑impedance output that drives a wide range of headphones while preserving control and dynamics.
- Flexible, transparent tone shaping and spatial tools (lossless UHD DSP + crossfeed) that tailor headphone response without obvious degradation.
- Robust, compact aluminium build, modern connectivity (USB‑C, optical, coax, micro‑USB) and Poly/desktop‑bypass support for versatile use cases.

Cons
- Menu and colour-coded control scheme is convoluted and has a learning curve—difficult to navigate by feel or in poor light.
- Premium price versus basic dongle DACs may deter users who prioritise cost over the Mojo 2’s advanced feature set.
- No balanced headphone output and limited headroom with the most demanding planar models—some desktop cans can approach the unit’s upper limits.
Sound Quality
92/100
Reviewers highlight excellent pace, timing and explosive transient response (Soundnews, StereoNET, HiFi News). Multiple tests noted improved dynamic swings and the ability to convey both large-scale impact and micro-dynamics without sounding clinical (Pursuit Perfect System, ecoustics). The Mojo 2 is described as fast with instant start/stop and authoritative control across genres.
Noise Floor
91/100
Specs and reviews report an excellent noise floor (2.7 µV, 123–125dB dynamic range) and reviewers repeatedly note a very low perceived noise floor or 'dead' silence between notes (HiFi+, The Ear, ecoustics). Several reviewers explicitly state it is suitable for sensitive headphones/IEMs and that small low-level details are preserved, supporting a near-black background performance.
Headphone Compatibility
90/100
Low output impedance (0.06 Ω) and solid power figures (600 mW/30 Ω; 90 mW/300 Ω) let the Mojo 2 drive a wide range of headphones from sensitive IEMs to many full‑size and planar models; reviewers successfully used it with Beyerdynamic DT770 (250 Ω), Hifiman Sundara and high-end closed/open headphones (Pursuit Perfect System, StereoNET, Soundnews). Dual gain ranges and broad volume control support flexible matching, though it lacks balanced headphone outputs which limits some pro/multi-cable workflows.
Build Quality
91/100
The Mojo 2 retains the machined single‑piece anodised aluminium case of the original and reviewers praise its solid construction, improved buttons and cooler running (The Audiophile Man, Pursuit Perfect System, The Ear). Multiple reviews call out excellent fit/finish and robust everyday portability, with chassis acting as a heatsink for desktop use (StereoNET).
Features Connectivity
94/100
Starts from the baseline portable amp feature set and adds a high-quality onboard FPGA/Pulse Array DAC (lossless UHD DSP), USB‑C data, micro‑USB, optical and dual‑data coaxial inputs, two 3.5mm headphone outputs, analogue outputs and dual gain ranges (StereoNET, The Audiophile Man, ecoustics). Extras like the transparent 4‑band tone controls (18 steps each), crossfeed, wide volume range, Poly compatibility and desktop-bypass behavior make it feature-rich for a pocketable unit, pushing the features score near the top of the allowed band.
Value for Money
92/100
Most reviewers feel the Mojo 2 justifies its price in the portable DAC/amp segment: called a 'red-hot bargain', 'no brainer upgrade' and 'can't do better under $1,000' by multiple outlets (Audiophilepure, HiFi News, Pursuit Perfect System). A few note the street price is high compared with cheap dongles, but consensus among specialist reviewers is that its performance and feature set represent a justified premium.
