## What is Phorus?

Breakthrough DTS Play-Fi(R) technology powers simple, great-sounding whole-home wireless audio systems for smartphones and tablets. You can stream your favorite tunes over Wi-Fi right from the Play-Fi app to speakers from DTS Play-Fi product partners. It's a huge step up from Bluetooth - the audio quality and reliability are outstanding, and you can enjoy music from your phone in one room, or all your rooms.

The "Hi-Fi over Wi-Fi" listening experience is just a touch away, thanks to this handy app. Choose a speaker, choose a song, and your favorite tunes are streaming all through the house.

The app offers built-in streaming options: stream from worldwide music services; use AM/FM and Internet radio, connect to DLNA servers, or play anything from your device's music library, including your iTunes playlists. The app automatically organizes and indexes the music for you.

The app also handles set-up for your speakers, and gives you full control of volume and speaker selection. Choose one, set up speaker groups, or stream to all of them at once.  Manage speaker groups for Spotify Connect, too.

IMPORTANT NOTE:  If you have a Play-Fi product from Polk Audio, Definitive Technology or Phorus, please search for and download the custom Play-Fi app for your audio brand.

Please also note that the Play-Fi app is companion software to audio products enabled with Play-Fi technology. It is not intended as a stand-alone audio player.

### 2/5 — Lowsy

*2025-11-30, version 8.72*

One of the worst app i have ever used Since the day I bought this speaker about 6 years ago till now I have not been able to hook up this peaker smoothly. I have since bought an Amazon Echo and is happy. The Phorus is just a very large paper weight.

### 1/5 — Garbage

*2024-05-14, version 8.52.4*

This app is absolutely useless

### 1/5 — Terrible app

*2023-11-05*

I wish they would stop “updating” this app because the updates don’t fix any of the issues, and only mean that you need to spend the next hour or two manually resetting every device (because the updates don’t actually get pushed to the devices). 

Terrible, useless app.

### 1/5 — Garbage, useless

*2023-06-19*

This crappy app (and their tinny-sounding, ridiculously-overpriced speakers) don’t work.  Buy a song from Apple? Phorus cant play it.  DUMB.

### 1/5 — Support non-existent

*2021-10-02, version 7.02.210915*

I used this app to play Amazon music and Pandora with their PR5 receiver. Was working well until the last firmware update. Now I can’t connect, nor can I reset the receiver to a factory state again. It is just bricked. Tried to contact Phorus support multiple times without hearing anything back. Frustrating!

### 1/5 — Really bad at managing devices

*2021-02-07, version 6.30.210108*

I got over it when it was tedious and required several restarts to bring my devices online in the first place, but the latest update *forced* me to update devices which are already working... And now it can't find them because apparently it loaded bad firmware? They no longer show up in Spotify either. The Play Fi team apparently needs some capable developers.

### 4/5 — Apple Music not working

*2020-12-06, version 6.23.201109*

Amazon music works.
Apple Music not working, throws file format unsupported error.

### 1/5 — Always stuttering and stopping

*2020-10-10, version 6.11.200720*

It seems that without updates the speakers are always giving issues. They keep pausing the music and stopping.

I have troubleshooted and the issue is not my wifi it is with the speaker. Usually after an update the problem goes away, but the issue seems to be that updates are always late!

I cannot depend on your speakers at all. I may have to switch to Sonos.

### 3/5 — Works well has a few issues

*2020-07-26, version 6.11.200720*

It works well but has a few issues with Spotify.  Can’t use any of the playback controls like the equalizer and the cross fade function.  AIRPLAY just doesn’t work, skips 3 seconds out of every 30.

### 3/5 — Update not so “up”

*2020-06-04, version 6.00.200526*

I just recently updated my phorus speakers and the app (Jun 3 ‘20).  The system worked great before the update, but since updating, there are constant “skips” or momentary loss of signal.  Funny because the update was to enhance the streaming of music within the app.  It’s not my system either, like I said it worked great before and also my speakers work seamlessly when I use airplay.  Please fix the update or send out a re-update of the previous app which worked great.
