Era 100 marks Sonos’s first use of dedicated angled tweeters in a compact speaker, creating a precise stereo image without a second unit. Its Bluetooth 5.0 radio accepts direct audio from phones and laptops as a standalone speaker, removing the dependency on a local Wi-Fi network. HDMI eARC on the optional line-in adapter connects to TV audio for a simple soundbar alternative. Trueplay acoustic tuning uses the device’s microphones to measure the room and adjust EQ automatically, optimising for placement on shelves or tables. Era 100 supports Matter bridging to act as a smart home audio output for automations.
