Chord Electronics Poly
Poly is a revolutionary music streamer, the first of its kind in the world. When partnered with Mojo 2/Mojo, it enables music streamed from a range of wirelessly connected devices to be enjoyed in the best possible sound quality, whether at home or on the go. Poly is also a music player: its unlimited-capacity Micro SD card slot can house huge libraries and liberate storage on smart devices. Full smartphone control using everyday apps enables effortless music playback whether streaming or playing music from the Micro SD.
Poly directly connects to Mojo 2/Mojo’s award-winning audio processing (DAC) technology dramatically improving the audio quality of streamed music. Its advanced design enables everyday devices, including Android and Apple smartphones/tablets, to become portable ‘hi-fi-quality’ digital audio players: the smartphone becomes the controller, with Poly and Mojo 2/Mojo doing the high-level audio processing.
Poly can also be used with computers and laptops, plus it can access networked audio stored on NAS drives using popular DLNA apps. Playback is via Mojo 2/Mojo’s twin headphone outputs, plus home and in-car audio systems with auxiliary (AUX) inputs can also benefit from the improved sound quality.
Poly connects to Wi-Fi networks, including mobile hotspots when on the go, and remembers multiple networks with its auto-connect functionality. It also benefits from Bluetooth® wireless technology, AirPlay and DLNA connectivity, offering uninterrupted music streaming when transitioning from indoors to outdoors. Poly also features its own hotspot mode, enabling a connection where devices, networks or countries do not facilitate tethering. Its rechargeable LiPo batteries offer up to nine hours of playback from a four-hour charge using the device’s fast-charging USB circuit; both Poly and Mojo 2/Mojo can be charged simultaneously.
Poly is high-resolution audio-compatible, with support for the latest studio-quality files; PCM data up to 768kHz resolution and DSD64 to DSD256 (Quad-DSD). Supported file types include ACC, WAV, FLAC, AIFF, OGG VORBIS, ALAC, WMA and MP3.

Chord Electronics Poly
Small, smart and sonically persuasive, the Chord Electronics Poly converts the Mojo into a portable, wireless high-resolution hub that reviewers such as Audiophilepure and StereoNET United Kingdom say can even outperform a direct USB connection. Paired with Mojo it brings greater clarity, texture and timing, tighter bass and improved imaging for a more detailed, dynamic presentation. Poly’s strengths include battery-powered microSD playback, Roon/DLNA/AirPlay/Bluetooth support and hotspot/Access Point modes; the iOS GoFigure app simplifies setup. The precision-machined aluminium chassis matches Mojo physically and feels like a single, purpose-built unit. Ideal for Mojo owners, mobile audiophiles and desktop users wanting to avoid noisy USB sources, Poly combines portability, broad format support (to 768kHz/DSD256) and practical streaming features that make it a compelling upgrade.
Pros
- Noticeable sonic uplift when paired with Mojo — improved clarity, texture, timing and bass compared with direct USB connections.
- High-quality build and seamless physical integration with Mojo — solid machined aluminium chassis and a secure, purpose-built fit.
- Broad feature set and format support — microSD local playback, Roon/DLNA/AirPlay/Bluetooth and PCM to 768kHz plus DSD256 for high-res workflows.
- Truly portable with long battery life and flexible networking — ~9+ hours of playback, hotspot mode and an integrated Access Point for on-the-go use.

Cons
- Wi‑Fi setup can be fiddly and Poly may refuse certain home networks, forcing workarounds like phone hotspot or firmware/app assistance.
- Bluetooth implementation is limited (A2DP/SBC) and native streaming services (Spotify Connect/Tidal native) were not available at launch.
Sound Quality
92/100
Multiple reviewers report clear, detailed and more musical presentation when Poly is paired with the Mojo DAC — in several accounts the Poly even outperforms a direct USB connection (Audiophilepure, StereoNET). Reviewers note improved clarity, texture, timing and bass heft (Audiophilepure: Bon Iver comments; StereoNET/SoundStage: 'upgrades sound quality' and 'supercharges the Mojo'), indicating the Poly reliably improves the sonic contribution to downstream DACs rather than colouring the sound.
Digital Signal Integrity
88/100
Reviewers attribute improvements versus USB to Poly's architecture: battery operation, local microSD playback, and use of Wi‑Fi/Bluetooth/AirPlay to avoid noisy PC USB links (Audiophilepure, SoundStage). These design choices provide electrical isolation from a host PC and reduce USB-bus noise, giving measurable improvements in timing, clarity and background noise. Reviews do not cite high-precision clock types or reclocking stages, so score reflects strong practical isolation/reduction of USB/PC noise rather than explicit femtosecond/OCXO clock claims.
Streaming Software
90/100
Poly supports Roon (spec), DLNA/UPnP, AirPlay and Bluetooth, and reviewers report a usable smartphone-based workflow; Chord's GoFigure app (beta noted by Audiophilepure) simplifies setup and mode switching. Reviews mention forthcoming native Spotify/Tidal features and reliable Wi‑Fi hotspot/Access Point modes, giving a polished and flexible streaming experience for a network streamer of this class.
Build Quality
90/100
Consistently described as excellently built with a solid aluminium chassis that matches the Mojo, Poly is praised for its compact, solid construction (SoundStage Solo, StereoNET). Battery-powered portability and neat mechanical design are highlighted; reviewers note typical Chord-level fit and finish, though the product's small portable form-factor limits expectations around heavyweight internal PSUs.
Features Connectivity
88/100
Poly offers a broad modern feature set: Wi‑Fi (including hotspot/Access Point), Bluetooth, AirPlay, DLNA/UPnP, Ethernet network access, Roon support, and a microSD slot for local playback (SoundStage Solo, multiple Audiophilepure reviews). It also supports very high PCM rates (to 768kHz) and DSD via DoP from SD card. That combination of network modes, local storage slot and high-resolution format support places it well above a minimal streamer.
Value for Money
90/100
At the stated price (~US$650) reviewers treat Poly as a compelling and justified purchase — many emphasize how it meaningfully improves the Mojo and offers a strong upgrade path for portable and home systems (Audiophilepure: 'compelling case'; StereoNET/SoundStage: 'worthy and essential upgrade'). Local bundle pricing (SoundStage Solo) also indicates attractive packaged value for those buying Poly + Mojo.
