Pair with Mojo 2

Poly directly connects to Mojo 2’s award-winning audio processing (DAC) technology dramatically improving the audio quality of streamed music (also pairs with Mojo). 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 improved sound quality.

Networking Machine

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.

  • Over-the-air software updates
  • Hotspot mode: Poly can create its own hotspot where networks/devices/countries don’t support tethering

Chord Poly

"Poly make Mojo sound much better, with Poly makes Mojo the best portable dac/amp on the market today"

Gennady B. (5/5)

Poly and Mojo 2

"The unit showed up with theaters FW. The sound is better than the Mojo 2 by itself. I’m looking forward to playing more files on the microSD. Setup was not too bad with the GoFigure app."

Sean F. (5/5)

Works Flawlessly - Highly Recommded

"I bought Poly for my new Mojo 2. From reading head-fi.org posts it looks like Poly had a pretty troubled launch years ago with all kinds of issues. I’m brand new to Chord products and was very pleasantly surprised that Poly works flawlessly. The app used to configure it works great. I don’t even need to tell Poly I want to switch between a Roon endpoint and Airplay - it just does it as needed. Poly means I can wander all over my house with my Mojo 2 and headphones and listen to Roon without the hassle and battery drain that comes with attaching a dongle to my iPhone. Streaming quality is at least as good as Roon ARC, maybe better. I have had zero dropouts from the wifi. An optical input to Mojo 2 might produce slightly better sound quality, but not by much. As I rip more of my old CD’s and buy more high res music files I plan to store them on the micro SD card in Poly so I have a network-free listening opportunity outside the home. If your use cases are like mine then I can highly recommend Poly. Regardless I can highly recommend Headamp.com!"

Great addition to Mojo2

"Much has been written about the Mojo2/Poly combo. It works well and sounds great. Deducting one star for micro USB charging. At some point they need to move entirely to USB-C for both devices."

Kevin K. (4/5)

Versatil and annoying at the same time!

"This unit bundles great with my Mojo 2 and there is no circumstance in which I cannot stream to the Mojo. The only annoying thing about it is the somewhat "primitive" interface for connecting to the Internet, forcing to sometimes hear at CD-res because of Bluetooth connectivity. When played at home, it becomes a great Roon streamer and and even a standalone DAC. this little thing does everything!"

Charlie (4/5)

Great SQ, decent features

"Painless set-up and great sound quality. Intelligent battery mode and a more intuitive hi-res hotspot set-up with the phone are to be desired."

Aashray K. (4/5)

Simply incredible

"Amazing sound quality and simple to set up. I use this coupled to Roon and could not be happier. Great service as usual from the folks at Headamp!"

Philip S. (5/5)

My favorite bluetooth device!

"The sound quality from the Poly/Mojo 2 combo is remarkably close to its already wonderful wired sound. Great combo and the additional wireless functionality is a bonus. Also, the Headamp customer experience is fantastic! Highly recommended!"
