This is a fair ask, sitting just under the median and squarely inside the normal used range. With comparable GBP listings clustered around £33 to £54 and a median of £43, £42 looks well judged rather than a bargain-bin steal or an overreach.
The ZP100 is still a solid older Sonos piece if you want simple multi-room playback and a built-in amp for a secondary system, kitchen, or workshop. At this price, the main thing to check is practical rather than speculative: that it powers up cleanly, connects properly, and includes any needed power/network leads, since age and missing accessories matter more than chasing perfection on a fair-priced unit.
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.
