Definitive Technology makes simple, great-sounding whole-home wireless audio systems for smartphones and tablets, including the iPhone, iPad, and the iPod Touch. Using DTS's breakthrough Play-Fi(TM) technology, you can stream your favorite tunes over Wi-Fi right from the app to the Definitive Technology Wireless Collection Speaker(s) connected to your existing stereo system. 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: use Pandora, Songza, Deezer, AM/FM and Internet radio, DLNA servers, or play anything from your iTunes music library, including your 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, or stream to all of them at once.

Please note that the Definitive app is companion software to the Definitive Technology Wireless Collection, and other products enabled with Play-Fi technology. It is not intended as a stand-alone audio player.

Functionally extraordinary

Once I figured out HOW to connect a speaker to my WiFi network (using the WPS or password options), it became easier to learn this app. That part was the most frustrating step in connecting. The app itself attempts to walk the user through it, but some steps aren’t clear—like how to get the white SLOW pulse. I still have no idea for what the other faster pulses are used.

This app is complex, with its numerous options available to the user, but I enjoy having the freedom to connect my DT speakers the way I want and listen to my libraries and playlists how I want. And, when there is a technical difficulty (like a disconnect), there are options to troubleshoot the problem and reconnect. Again, the complexity of this app seems purposeful and allows the user the freedom to choose from more options than the ordinary app. I am able to walk through my house and hear my music in various rooms without running wires in the attic or crawl space. Using the WiFi in my house as it’s network works very well and is satisfying. Overall, I’m enjoying this app very much.

This app is horrible

Their cheapest speakers are priced at $399; that’s how much they’ve seemed to invested into this app. The list goes on: nuisance to connect with the horrible Hi-Fi speaker system, problems playing music to speakers after they’ve finally been connected, music cutting off after thinking its finally working fine. I tested this system with the W7; W9; and orinal Wsoundbar and sub woofer for 3 years a small one family home with 1,000mbs internet speed. The speakers are okay for being WIRELESS speakers... that is if you plug it with a cable. Horrible products in their wireless line. Will never buy from Definitive Technology ever again.
