Adding the Play:5 to an existing Sonos setup is dead simple. You just plug it in, go to your computer and click "add zone" in the desktop software menu, then return to the Play:5 and press the mute and volume up buttons simultaneously on the device. Within 10 to 30 seconds, the Play:5 will be recognized and added to your existing zones (you name it for whatever room it's in). Once it's part of the system, it will show up on your Sonos remote or on your iPhone, iPod Touch, iPad, or Android smartphone with the Sonos app running.
The experience of using your phone or tablet as a Sonos remote is as good as it is because the interface of the Sonos iPhone app is quite easy to use. You can easily sync zones so the same music plays in all rooms or have different music playing in different zones. For instance, you could have Pandora playing in one room and have an album stored on your computer playing in another room. You can also choose to turn certain zones on and off and raise the volume in one room while lowering it another.
If you're new to Sonos and setting up the Play:5 for the first time as a single or multizone system, the process is fairly straightforward but things can get a bit trickier if you want to pull all your music from a networked drive. Also, when you're dealing with any sort of networking--wired or wireless--you can run into snags that might baffle the average person (and even plenty of tech-savvy people). But all in all, Sonos' does this type of DIY multiroom audio--and the setup that's involved--about as well as any company we've encountered. It's also worth noting that if you were to get a professional installer to equip a home with in-wall speakers and a special networked system (for instance, Crestron), you'd be looking at thousands of dollars per room instead of hundreds.
So, while the Play:5 does require other components to make it work, as we said in our introduction, what's nice about it is that you get a speaker and ZonePlayer combined into a single unit for a relatively affordable price. Previously, you had to connect a set of speakers to a ZonePlayer to hear any music and the setup wasn't ideal for certain spaces, particularly kitchens or bathrooms, where you don't want to deal with trying to hide speaker wires running from a little box that has to be plugged in. It also doesn't help that certain ZonePlayers, like the ZP90, are ampless and require you to have powered speakers that also need to be plugged in.
As for the sound quality, it's quite good, comparatively speaking. The Play:5 boasts a total of five drivers: behind the non-removeable grille, a single woofer is flanked by two midrange drivers and a pair of tweeters, each of which are powered by a dedicated digital amplifier. The only problem is that similar to all compact iPod speakers, the drivers are spaced so closely together that you don't get a whole lot in the way of stereo separation (these types of speakers tend to sound best when you're sitting about 4 feet away from them).
That small knock aside, the Play:5 is a well-balanced speaker that offers good detail and a decent amount of bass without sounding thumpy. It's also able to play loudly without distorting and it did a decent job filling a fairly large room with sound. We listened to a wide variety of music on it, from Elvis Costello to Bach to Rihanna to assorted techno, ambient, and electronica tracks, and its sound was consistently smooth and never brash.
Against the competition, it measures up quite well to various "refined" iPod speaker systems we've seen from Bose, B&W, and other luxury brands in this price class, and bested B&W's smaller $400 Zeppelin Mini in our tests. When we put it up against Bose's larger and pricier SoundDock 10 ($600), it didn't sound quite as big, but it wasn't far behind in terms of overall sound quality.
Sonos also allows you to "stereo pair" two Play:5s, so you can set them as the left and right speaker for wider stereo imaging.
Bottom line, we liked what we heard, and the Play:5 clearly marks an important step for Sonos as it works toward offering a more streamlined product offering. The combination of iOS and Android phone compatibility and an integrated speaker/ZonePlayer make the Sonos system that much more appealing, especially when it comes to adding Sonos to rooms where speakers are hard to place. Our only (minor) reservations come from the setup caveats for first-time Sonos customers--the requirement to go Ethernet or invest in the $49 Sonos Bridge accessory. But for existing Sonos customers, the Play:5 will be a welcome and enthusiastic addition to the system.
