Audio T Verdict
Poly is the little module that turns Chord Electronics' brilliant Mojo 2 into a genuinely portable wireless music player. Attach the two together and you can stream over Wi-Fi, use AirPlay or Bluetooth, access music across your home network or carry a large music library on a Micro SD card.
The clever bit is that Poly handles the streaming and storage while Mojo 2 remains responsible for the digital-to-analogue conversion and headphone amplification. You get the convenience of a modern wireless player without replacing the DAC and headphone amplifier you already own.
Poly is equally happy at home or on the move. Its own hotspot mode means you don't necessarily need an existing Wi-Fi network, while its internal battery provides around nine hours of playback.
If you already own a Mojo 2 and want to remove the cable between it and your phone, Poly is the obvious upgrade. The original Mojo is still supported too.
Chord Electronics Poly Wireless Streamer and Player
Poly is a compact wireless music streamer and player designed specifically to connect directly to Chord Electronics Mojo 2 and the original Mojo.
Once attached, the combination becomes a complete portable network music player with support for:
- Wi-Fi music streaming
- Bluetooth wireless playback
- Apple AirPlay
- Roon Ready playback
- DLNA streaming
- Music stored on Micro SD card
- Network storage and compatible NAS libraries
- Portable hotspot operation away from your home network
Designed for Mojo 2
Poly connects directly to the side of Mojo 2, creating one compact portable unit without requiring a separate digital cable between the streamer and DAC.
Mojo 2 handles the digital-to-analogue conversion and headphone output, while Poly provides the wireless, network and local-storage functions.

Already Own the Original Mojo?
Poly remains compatible with the original Chord Electronics Mojo as well as Mojo 2.
This means existing Mojo owners can continue to use Poly even though Mojo 2 is now the current-generation DAC and headphone amplifier.
Wireless Music Streaming
Poly provides several ways to get music to Mojo without physically connecting your phone, tablet or computer to the DAC.
Wi-Fi
Long-range 2.4GHz Wi-Fi provides the main network connection for high-quality streaming at home.
Bluetooth
Bluetooth provides a quick and convenient wireless connection from compatible phones, tablets and other devices.
AirPlay
Apple users can send compatible audio directly to Poly using AirPlay from iPhone, iPad and other supported devices.
Roon Ready
Poly can operate as a Roon Ready network endpoint within a compatible Roon system.
High-Resolution Network Playback
Poly supports high-resolution audio up to:
- PCM: 768kHz
- DSD: DSD64 to DSD256
- DSD transport: DoP supported
The final digital-to-analogue conversion is performed by the connected Mojo or Mojo 2.
Current DSD Specification
Older Audio T copy refers to DSD512. Chord Electronics' current Poly specification states support up to DSD256, so the current manufacturer figure is used here.
Micro SD Music Player
Poly includes an onboard:
Micro SD card slot.
This allows music to be stored with Poly itself rather than occupying storage space on your phone or relying on an internet connection.
Chord Electronics describes the Micro SD capacity as effectively unlimited, allowing very large music libraries to be carried with the Mojo/Poly combination.
Local Music without the Internet
Music stored on the Micro SD card can be played without needing to stream the audio file from the internet.
This makes Poly particularly useful for:
- Travelling
- Commuting
- Using Mojo 2 away from home
- Large lossless and high-resolution music libraries
- Reducing dependence on phone storage
DLNA Server and Renderer
Poly can function as both a:
- DLNA server
- DLNA renderer
This allows it to integrate with compatible control apps and network music libraries.
The Micro SD card can also be exposed through Poly's network services for compatible devices and applications.
Gofigure App
Initial setup and configuration are handled through Chord Electronics' free:
Gofigure app for iOS and Android.
Gofigure is used for tasks including:
- Initial network setup
- Adding Wi-Fi networks
- Managing Poly settings
- Firmware updates
- Hotspot configuration
- QuickPlay access to compatible Micro SD playlists
Convenience Switching
Current Poly firmware includes convenience switching between Roon and other playback services.
This means changing from one compatible playback method to another no longer requires the older manual mode-switching process.
Hotspot Mode
Poly can create its own:
Wi-Fi hotspot.
This is particularly useful when travelling or when an existing network is unavailable or unsuitable.
Your phone or tablet can connect directly to Poly's hotspot for control and playback.
Useful Away from Home
Hotspot mode allows Mojo and Poly to operate as a portable music-player combination without relying on the Wi-Fi network in a hotel, train, office or other unfamiliar location.
Remembers Multiple Networks
Poly's integrated access point can store configuration information for:
Up to 32 networks.
This makes it easier to move the player between regularly used locations without entering the network details again each time.
Up to Nine Hours of Battery Life
Poly contains a:
2200mAh rechargeable lithium-polymer battery.
Chord Electronics specifies more than nine hours of playback from a charge, making it suitable for portable use alongside Mojo or Mojo 2.
Fast USB Charging
Poly uses USB charging and can be fully charged in approximately four hours with a suitable charging supply.
Both Poly and Mojo can also be charged simultaneously through Poly's charging connection when the two units are attached.
Use a Suitable USB Power Supply
Charging performance depends on the available USB power. Use a suitable, good-quality USB supply and the correct cable.
Precision-Machined Aluminium Case
Poly uses a precision-machined aluminium enclosure finished in black anodising, with an opaque wireless-signal window and silicone feet.
Its dimensions closely match Mojo and Mojo 2 so the products form one compact unit when connected together.
Compact and Lightweight
Poly measures:
- 50mm long
- 62mm wide
- 22mm high
- 91g
The complete Mojo 2 and Poly combination therefore remains small enough for portable headphone use.
Current Firmware
Poly continues to receive software support from Chord Electronics.
Firmware updates are handled through Gofigure and have brought improvements including:
- Network stability
- AirPlay performance
- Roon operation
- Bluetooth functionality
- DLNA server performance
- Micro SD handling
- Convenience switching
Chord Electronics currently lists Poly firmware version 3.2.4.
