## What reviewers say

**Amazon Echo (4th Gen)** — Four whitelisted testers — What Hi-Fi, SoundGuys, Tom's Guide and Reviewed — hands-on reviewed the exact 4th-gen Echo. Consensus: a well-rounded, great-value Alexa smart-home hub with a distinctive orb design and punchy bass, but recessed treble and mids, and sound clearly bettered by pricier rivals like the Sonos One. (4 sourced reviews.)

**Sonos Era 100** — All four whitelisted testers (PCWorld, What Hi-Fi, TechRadar, Tom's Guide) reviewed the exact Sonos Era 100; the separate 'SL' variant was excluded. All agree it clearly upgrades the Sonos One with bigger, deeper bass, more detail, and new Bluetooth plus optional line-in flexibility. Only PCWorld took instrumented measurements, peaking at 90 dB while streaming (88 dB via line-in, 82 dB internet radio). TechRadar dissents on the bass, calling the deeper low-end 'a bit flabby.' (4 sourced reviews.)
