Independent testing
How much independent testing exists for each over ear headphone
Of the 9 over ear headphones we track, 9 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 |
|---|---|---|---|
| Bose QuietComfort 45 | 2 | 2 | 3 |
| Sennheiser Momentum 4 Wireless | 2 | 2 | 4 |
| Sony WH-1000XM5 | 1 | 9 | 1 |
| Sony WH-1000XM6 | 1 | 6 | 3 |
| Marshall Monitor III ANC | 1 | 4 | 3 |
| Apple AirPods Max (USB-C) | 1 | 3 | 1 |
| Beyerdynamic Aventho 300 | 1 | 3 | 2 |
| Bose QuietComfort Ultra Headphones | 1 | 2 | 3 |
| Bowers & Wilkins Px7 S3 | 1 | 1 | 4 |
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 Over Ear Headphones buying guide and the reviewers we cite.
