Ik stap over op hi-fi en verkoop daarom mijn twee sonos era 300's. Ze werken perfect en verkeren in zeer goede staat.
At €700, this is above the typical used market for an Era 300: your own comps put the median at €383 and the 75th percentile at €548, so this listing is clearly ambitious for a single used speaker. New pricing has sat around €499, and even fresh used/open-box examples are often well below this level, so I’d only engage if there’s something unusually strong about the package or provenance.
That said, the Era 300 is a genuinely impressive buy when priced right: it’s one of Sonos’s best-regarded spatial-audio speakers, with wide, room-filling output and strong Dolby Atmos performance for its size. If this is truly excellent condition, ideally with box and original accessories, it’s still a capable piece of kit—but at €700 the buyer should expect a near-new story, not just “clean used.”
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.
