Independent testing
How much independent testing exists for each smart speaker
Of the 10 smart speakers we track, 4 have been physically measured by at least one independent lab. Below is every one, ordered by how much independent hands-on evidence stands behind it — densest first.
A coverage record, not a ranking of which is best.
| Product | Independent labs | Metrics measured | Outlets on record |
|---|---|---|---|
| Sonos Move 2 | 2 | 1 | 4 |
| Amazon Echo (4th Gen) | 1 | 2 | 4 |
| Google Nest Audio | 1 | 1 | 4 |
| Sonos Era 100 | 1 | 1 | 4 |
| Amazon Echo Dot (5th Gen) | 0 | 0 | 4 |
| Amazon Echo Studio (2nd Gen) | 0 | 0 | 3 |
| Apple HomePod (2nd Gen) | 0 | 0 | 3 |
| Apple HomePod mini | 0 | 0 | 4 |
| Google Nest Mini (2nd Gen) | 0 | 0 | 3 |
| Sonos Era 300 | 0 | 0 | 3 |
Each figure is a count of what independent testers actually did — how we count. A low count means little independent evidence has been gathered yet, never that a product is worse. See also the Smart Speakers buying guide and the reviewers we cite.
