US$550 is ambitious against your recent comp set: it sits well above the US$377 75th percentile and far over the US$185 median, so this is priced for a seller who is asking near the top of the market, not for a bargain hunter. Even with “tested working,” I’d want a strong reason to pay this much over the norm.
That said, this is a genuinely capable piece if you want one box to do the work of a system hub: enough power for efficient passive speakers, clean integration for a straightforward 2.1 setup, and Sonos’ usual strength in multiroom convenience and app control. The upside is simplicity and system cohesion, especially if it comes with the right power cord and any needed accessories. At this price, though, I’d only move if you specifically want the Sonos ecosystem and can confirm everything works perfectly.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
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.
