Overview
The Sonos Era 100 is a compact, mains-powered wireless speaker for home listening. It is a useful starting point for shoppers searching broadly for a Sonos product: unlike a soundbar, it does not need a television, and unlike a portable speaker, it is designed to stay plugged in. Wi-Fi streaming, Apple AirPlay 2, and Bluetooth give it several ways to play music. It also works within a Sonos multiroom system, allowing compatible speakers in different rooms to play together.
Inside are two angled tweeters and one midwoofer. That arrangement gives a single Era 100 some stereo separation, although it cannot reproduce the physical spacing of two separate speakers. Reviews generally praise its balanced sound, useful bass for its size, and clear vocals. Trueplay tuning can adjust playback to the room, helping when placement is less than ideal. The Era 100 does not support Dolby Atmos music; buyers wanting that feature should look at other models rather than assume every recent Sonos speaker includes it.
Who it's for
The Era 100 suits listeners who want an everyday kitchen, bedroom, or office speaker with the option to expand later. Owners of existing Sonos equipment have an additional reason to consider it: the speaker fits into the same app-based ecosystem. Two Era 100 units can form a stereo pair, or a pair can serve as surrounds with a compatible Sonos home-theater setup. Either route adds expense, so compare the total system cost rather than just the price of one speaker.
It is also worth considering if different household members use different phones or streaming services. Bluetooth offers a straightforward playback option after setup, while AirPlay 2 is convenient for Apple users. However, it is less suitable for outdoor trips, battery-powered listening, or direct TV connection. Buyers who mainly want a voice assistant should check supported services carefully: Amazon Alexa and Sonos Voice Control are options, but Google Assistant is not supported on this model.
Things to know before buying
Initial setup requires the Sonos app and a Wi-Fi network. Sonos software has attracted substantial criticism since its 2024 app redesign, with users reporting setup, reliability, and feature problems. Experiences vary, and software changes over time, so check recent owner reports and buy from a retailer with a practical return policy. Bluetooth does not make this an entirely app-free product.
The USB-C port supports optional Sonos adapters for line-in or Ethernet; those accessories cost extra. Connecting a turntable also requires an appropriate line-level signal, usually from a built-in or separate phono preamp. There is no HDMI input. When comparing US listings, distinguish a single new speaker from a two-pack, refurbished stock, or an accessory-only offer, and account for any adapters you actually need.
