Every number on this page was measured. Not copied from a spec sheet.
What makes something worth publishing here is a straightforward standard: the review must tell a specific buyer something they couldn’t find by reading the product page. That means a Spec Gap measurement where one exists, a verdict framed around an actual use case rather than a theoretical average user, and at least six weeks of time between first power-on and first sentence written. What you won’t find here: reviews written from press junket units, verdicts that refuse to commit to a specific recommendation, or a product recommendation so heavily hedged it functions as no recommendation at all.

Where the most consequential
gaps turn up
Four coverage areas where the distance between spec sheet and real-world performance tends to be large enough to change the purchasing decision.
The Spec Gap
Battery figures measured at conditions no one actually uses. ANC attenuation rated in isolation from the noise profiles real commuters encounter. This is the series where manufacturer claims meet measurements — and where the gap between them becomes the actual finding.
Laptops & Portable Computing
Thermal throttling at hour four. Battery estimates that drop 30% in the first month as the cycle count climbs. The workload that separates an ultrabook from a mistake.
Headphones & Earbuds
ANC attenuation tested across three noise environments, not one anechoic chamber. Driver quality versus hardware quality — and why they aren’t the same thing.
Storage & SSDs
Sequential read headlines are marketing. Sustained write performance after cache saturation is the number that matters when you’re moving a 100GB video project. We test both.
