For years, Sonos made its name with WiFi streaming alone, avoiding Bluetooth at all costs to keep audio quality high. It finally relented with portable speakers, realizing convenience does matter for some use cases without invalidating the core WiFi basis of what makes Sonos so great. The Era 100 competes directly with Bose and Sony’s premium offerings while it currently sells for mid-range pricing that makes no sense given its capabilities. Amazon dropped this to $169 for Black Friday, down from $199, which is a record low that puts exceptional audio within reach of anyone looking for Bluetooth speakers.

47% Faster Processor Powers Dual-Tweeter Architecture
The next-generation processor handles more complex audio processing in real time and enables features that previous Sonos speakers couldn’t support. Dual tweeters create genuine stereo separation from a single speaker, placing instruments and vocals in distinct left and right positions. This architecture produces a soundstage that fills rooms rather than feeling like sound emanates from a single point. The 25% larger midwoofer extends bass response deeper than the previous generation, and gives kick drums and bass lines actual impact without needing a separate subwoofer for most music.
This compact design fits easily on bookshelves, kitchen counters, desks and nightstands. You place the speaker wherever you really spend time, rather than arranging furniture around audio equipment. The size makes it truly portable inside your home and moves from room to room as the day progresses with you. It weighs enough to feel substantial yet remains light enough to carry easily in one hand.
Wi-Fi streaming provides lossless audio quality from the likes of Spotify, Apple Music, Tidal, and Amazon Music. The connection also remains stable throughout a home without the dropouts that plague Bluetooth in larger spaces. You control playback through the Sonos app which aggregates all of your streaming services into one interface. AirPlay 2 support adds another streaming option for Apple users who want to send audio directly from their devices.
Bluetooth connectivity handles quick pairing with phones, tablets, and laptops when you want simple wireless playback. You press a button on the back of the speaker, and instantly, your device finds it. This mode is great for playing podcasts, audiobooks, or music from apps that aren’t integrated into the Sonos ecosystem. The implementation of Bluetooth maintains decent quality, though Wi-Fi streaming sounds noticeably better when that option is available.
The Line-In Adapter includes a 3.5mm auxiliary input to connect turntables, CD players, or other analog sources. This adapter is available separately but turns the Era 100 into a powered speaker for vinyl setups or legacy audio equipment. It combines digital streaming with analog input flexibility that pure Bluetooth speakers simply can’t compete with.
Trueplay tuning uses your iPhone’s microphone to analyze room acoustics and then automatically adjust the speaker’s EQ. You wave your phone around the listening area for about a minute, and it makes a custom sound profile optimized for your particular space. This calibration compensates for room characteristics, such as hard surfaces that create reflections or soft furnishings that absorb sound. The difference between tuned and untuned sound is immediately noticeable, with vocals becoming clearer and bass tightening up.
Alexa integration enables voice control for music playback, smart home commands, and general queries. The built-in microphones pick up voice commands clearly even when music plays at moderate volumes. You can add the Era 100 to multi-room setups with other Sonos speakers, creating a whole-home audio system that plays synchronized music everywhere or different content in each room. This ecosystem approach means starting with one speaker and expanding over time as budget allows.
For $169, you’re getting Sonos premium audio engineering, with both WiFi and Bluetooth for less than mid-range speakers elsewhere that can’t compete on sound quality. Similarly priced Bose and Sony speakers rely exclusively on Bluetooth and don’t have the multi-room capabilities that make Sonos special.
