I hadn't heard of the Swedish consumer audio manufacturer Nocs at all when it began sending WIRED review units of its goods a few years ago. But I quickly grew to respect Nocs, especially after it produced a few pairs of excellent earbuds, including the NS400 and the NS600, and a killer pair of on-ear headphones, the NS900.
A couple of Christmases ago, Nocs shipped over the NS2, its set of desktop AirPlay speakers. They're well-designed: 80 watts, Kevlar drivers, compact 6-inch-tall enclosures, and dressed in either basic black and white or bright colors like orange and yellow. I liked everything about them except for the fact they ran AirPlay. Apple's wireless media platform works perfectly for some people, but it's still buggy and unstable for most of us, and too unreliable for me to commit to, especially in a set of speakers costing several hundred dollars.
The NS2s are back now in a "version 2" model priced at $400, and they're much improved. Nocs has added two additional methods beyond AirPlay to wirelessly play music: Bluetooth and Spotify Connect. The adoption of Bluetooth is what really completes the package, turning a pair of nice-sounding but flawed desktop speakers into a well-rounded audio setup I can easily recommend.
In my testing of the new Nocs, AirPlay was still problematic—it's susceptible to interference from other wireless networks and devices, and suffers from frequent dropouts in high-traffic areas. (It may work for you, but you'll know what awaits if you already have a few AirPlay devices in your home). Whenever AirPlay acted up during testing, however, I could just switch to either the Spotify direct-connect mode (better but not perfect) or to Bluetooth (zero hiccups, near flawless).
It's a shame about AirPlay that even years into the life of the platform and wide adoption among manufacturers, I'm still seeing so many products that barely work as streaming devices. Bluetooth, on the other hand, has done nothing but get better over the last few years. Audio quality, signal stability, and the drain on the battery of whatever mobile device you're using for playback have all improved. Not to mention that it's device-agnostic and super-easy to set up. At this point, all of my favorite wireless speakers are either Bluetooth-only, or they have Bluetooth in addition to another platform, like AirPlay or DLNA. And I almost always just use Bluetooth to avoid all the potential hassles of Wi-Fi-based audio.
