This US$55 asking price is a strong bargain, sitting well below the 25th percentile of US$106 and far under the median of US$185 from 804 recent comparable listings. The ZP120 is the original powerhouse of the Sonos ecosystem, now rebranded as the Connect:Amp, and remains highly valued for its robust 55W built-in amplifier that easily drives passive speakers without an external amp. Including the power cable and a factory reset makes this a clean, ready-to-integrate entry into multi-room audio, offering genuine upside for anyone building a system or needing a reliable wired streaming source.
At this price, there is no need to worry about age or missing accessories; the included cable and reset procedure signal a seller who understands what enthusiasts want. The ZP120’s proven reliability and seamless integration with modern Sonos apps make it a timeless piece, especially when found this cheap. Grab it as a buying opportunity—it’s a rare chance to own a legendary Sonos amp at a fraction of typical used value.

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.
