Our Thoughts RADAR AI

The CR100 is a neat piece of early Sonos history, but at A$170 it’s only a fair buy if it’s complete and working; these usually trade as legacy collector/utility pieces rather than must-have daily controllers. Without a clear condition note, I’d call the price okay but not cheap for a discontinued accessory, especially since support ended years ago and value depends heavily on whether it still powers up and holds charge.

What makes it worthwhile is the old-school Sonos convenience: a dedicated handheld controller with a built-in screen, dock, and charger, which is still appealing if you’re running a legacy Sonos setup or you collect first-gen kit. The upside is strongest if the listing includes the charging base and adapter and the battery is healthy; if not, I’d be cautious, because missing accessories or a tired battery can turn a fair price into a mediocre one fast.

Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.

About Sonos

Sonos emerged from Santa Barbara, California, in 2002 as Rincon Audio, Inc., founded by John MacFarlane, Craig Shelburne, Tom Cullen, and Trung Mai. MacFarlane's success with Software.com provided crucial seed funding for their audacious goal: a wireless multi-room music system free from the wires and complexity plaguing home audio at the time. Renamed Sonos in 2004, the company debuted its pioneering ZonePlayer and controller in 2005, cementing its roots in innovative, user-centric sound technology.

The brand specializes in wireless speakers, soundbars, and home theater systems designed for seamless multi-room playback and integration with streaming services. Sonos offers everything from portable Bluetooth options like the Roam to high-fidelity architectural speakers and subwoofers, alongside recent forays into headphones and whole-home audio solutions. Amplifiers, turntables, DACs, and cables fall outside their core focus, which prioritizes app-controlled ecosystems over traditional hi-fi components.

Sonos holds a commanding mid-to-premium position in the consumer audio market, renowned for inventing wireless HiFi and setting the standard for effortless, high-quality sound. Trusted by audiophiles and casual listeners alike, it blends accessibility with sonic excellence, dominating the smart speaker segment while appealing to discerning buyers seeking scalable, future-proof systems.
