Below is our own user-contributed manual explaining what Poly does, how it does it and what your options are.

In addition, you can check out the Chord Poly Frequently asked questions/issues section. If you're a brave soul, you can also delve deep down the rabbit hole to learn some background on the Chord Poly.

Known issues/bugs and Wishlist/Feature Requests

Click here for the current index of issues, feature requests and other in-development type stuff

We are keeping an eye out for common issues and more importantly trying to provide Chord Electronics as much information as is possible in this section. You will find descriptions of issues as well as the underlying causes and ways to recreate the issue.

Other Information

This main page includes basic setup and operation of your Chord Poly. In addition to this there are several other more advanced topics you may wish to view listed below:


Chord Poly is a small streaming device made exclusively for use with the Chord Mojo digital audio converter (DAC). It outputs music to the Mojo using a MicroUSB connection, and it gets its music from either a MicroSD card inserted directly into Poly, or from “the network” using “Digital Living Network Alliance” DLNA control/streaming, AirPLay or Google Cast.

Poly has a WiFi interface capable of 2.4GHz wifi, but not 5Ghz. This means you will need to make sure your Wifi network is set up to include the 2.4GHz band.

On the front of the Poly you can see two status lights, labelled M Status and P Status - short for Mojo Status and Poly Status. The M.Status light is in fact lit up by a piece of clear plastic, a light pipe, that connects this hole to the actual light on the Mojo itself.

The lights themselves are embedded into a small plastic window - this is covering the Wifi and bluetooth antennae in order to not have them be blocked by the metal chassis of Poly.

To the right of the M and P Status lights, roughly in the center of the unit, is a MicroUSB port, used to charging the Poly and Mojo.

To the right of the charging port is a MicroSD card slot where you can insert any sized MicroSD card, formatted FAT32 or ExFAT.

Immediately under the MicroSD card slot is a small hole labelled “Config” - inside is a push button that you can press using a paperclip or the provided Poly config tool in order to switch modes of the Poly.

You will almost certainly be using this until the GoFigure app is available in the appropriate App Store.


The charging should take around 4 hours during which the white lights for both he Mojo Status (M Status) and Poly Status (P Status) will glow white. Your initial charge should be done for about 6 hours in order to give the Mojo and Poly batteries the best possible start in life.

Using the correct type of power adapter

Plug your Poly/Mojo combo into a good charger - one that delivers 2.4A of current in order to charge both simultaneously.

Poly has some clever charge sensing circuitry so if you have a charger that is not quite powerful enough to charge both products together then it will prioritise charging Mojo first. This is why you might see Mojo ( M Status ) light off but P Status light on Poly still white and charging

You can find a ton of good chargers on Amazon which support 2.4A - here is a link to a good search for Anker chargers, which work well.

Poly/Mojo can be charged at best speed on desktop and laptop computers that have USB 3.1 using the reversible Type-C connectors which supply 5V @ 20A.

Laptops or desktops with the older USB 2.0 and 3.0 Type-A to Type-B connectors which supply 5V @ 1.8 A may charge more slowly.

Some operating systems apply power management to the USB ports that lowers the available power when multiple devices which draw current are attached. It is therefore best to charge Poly/Mojo when no other USB devices are drawing power from if at all possible if shortest possible time is critical.

Charging status lights

The charging should take around 4 hours during which the white lights for both he Mojo Status (M Status) and Poly Status (P Status) will glow white. When they are fully charged, the Mojo light will turn off and the Poly light will turn solid blue.

When you unplug the charger the lights will switch back to their normal state showing the level of charge in the batteries for both devices:

Poly usually follows the same light codes for battery level as the Mojo, unless you are in Poly Hotspot mode, where it will instead flash blue and green.

Charging noise

The charging noise is caused by high frequency switching circuits that supply the precise power that both the Poly’s and The Mojo’s batteries require to be safely charged as rapidly as possible without degrading them to insure as long a serviceable life as present battery technology allows for. The actual noise is generated in tiny ceramic capacitors which can act just like the ceramic resonators in earpieces they are virtually the same sort of device and the noise can come from the tiny wound inductors in our units especially if the bulk input wall charger give out an irregular or pulsed output- some do! -some don’t! This matters for noise heard coming from our devices but it doesn’t matter in terms of the reliability of our units. Therefore please don’t worry no damage is being done to Poly Mojo or your charger.

Getting to the latest version

In order to get updated to the latest firmware version on your Poly, if you do not have the GoFigure App, you will need to get Poly connected to your home network or your phone's hotspot as detailed below in the Network Connections section and then follow these instructions to update your poly

Getting the GoFigure App

The free Gofigure app allows easy network setup and simple settings management, such as selecting between Roon and Everything Else mode, all within a slick and powerful user interface that’s easy to navigate.

Gofigure also features an innovative set-up wizard that configures both new and existing Poly’s to available WiFi networks and Bluetooth, as well as providing step-by-step configuration for those requiring the use of Hotspot mode. You will also see a new feature named QuickPlay. Although QuickPlay is not intended to replace third-party control point apps, such as Glider and 8 Player, it allows convenient playback of MPD generated playlists stored on your Micro SD card, when you don’t want to frequently interact with your device – such as at the gym.

Install GoFigure on iOS by tapping here from your iOS device.

Network Connections

Note: Chord Poly only supports 2.4GHz networks. Your rouer/wifi setup must support 2.4GHz WiFi. A firmware issue seems to have Poly advertise to network wifi devices that it can do 5GHz which may cause unintended issues. See here for more details

The Chord Poly currently supports three main ways to connect to your phone in order to be controlled:

  1. Using your home Network
  2. Using your Phone's Hotspot
  3. Using the Poly Hotspot (Poly light flashes blue/green in this mode)

For the first two options, you essentially tell Poly the names and passwords of your networks, and it'll connect to whatever one it finds. Unfortunately there is no consistent way to prioritize one over the other, so when you are home and try hotspot things may be flakey.

In hotspot mode the poly acts like a router and makes its own network you can join, normally named Poly-123456789 - though the numbers for you will be different.

Music Player Apps

GoFigure Basic Playback


Using DLNA or MPD requires that you download a separate music client app that runs on your iOS, Android or other device. There are several available.

DLNA Players

  1. Glider Audio Player Highly recommended.
  2. 8 Player Recommended.

MPD Players

  1. MPDluxe Recommended.

Depending on what you are trying to do, different setups with different app combinations for certain goals. Easy, right?

Manually Configuring Poly using the Config tool

Recommended settings and setup videos for iOS

Please make sure you are on iOS 11.2 or later. There were significant issues with iOS 11.0 and 11.1 in terms of connectivity. Be aware that if you upgrade your iOS to a new .0 release you should be suspicious of your iOS device more so than Poly for any drastic reductions in functionality.

Currently the latest version of iOS 11.x is the most stable for Poly.

Normal iOS Setup

In this scenario, you are probably best set to use your iPhone hotspot, if you have one. If you do not, or you find it flakey, you could use Chord Poly's hotspot feature. iPhone hotspot mode requires little else other than turning it on, but some folks do not have a hotspot function in their contracts, and it seems a little less reliable.

To switch from home/office to hotspot, just activate your iPhone hotspot and walk out the door.

Basic Troubleshooting:

If your Poly light flashes constantly and does not go solid, you need to re-check your WiFi settings by going back into hotspot mode.

If your Poly light goes solid and you are unable to “see” Poly from your phone and are sure theyre on the same network, it is likely your Wifi gear is advanced and works correctly, but you are running into a bug with Poly. See here for more details.

iOS using Poly in Poly's own hotspot network

There are a few reasons you would want to use Poly's own hotspot instead of your Phone. First, if you have no Hotspot capability on your phone. Second, if you are getting on a plane and need to use Airplane mode (Which doesn't let you use hotspot mode on a phone) Finally, if you are experiencing flakiness on other settings and especially if you notice dropouts and the P.Status light blinking and going back to solid when it happens - indicating network connectivity issues..

The downside of using Poly as a hotspot it that it “steals” your internet connection, rendering your phone useless except for calls and controlling Poly… unless you make some changes…

We recommend using “Poly Hybrid Hotspot Mode” as detailed below if you dont have Hotspot service or if you are finding Poly a little flakey:

Best setup in order to play music from your Chord Poly's MicroSD card is to use the Poly Hotspot, but also removing the default gateway from the configuration so your phone can remain connected to the internet using its data service instead of trying to use Poly for Internet access.

This gives you the most stable playing experience for playing from the MicroSD card using a DLNA client. My favorite one is Glider Audio Player and the below video shows you how to set this up:

For another video, you can check out another explanation of why this works here.
