The Audio Knowledge Base is a set of short plain-English explainers for jargon you see on headphone, earbud, soundbar, and TV product pages — ANC, Atmos, eARC, codecs, IP ratings, and more. Each page tells you what the term means, when it matters for a buy, and when you can safely ignore the badge.
Quick answer
The Audio Knowledge Base is a set of short plain-English explainers for jargon you see on headphone, earbud, soundbar, and TV product pages — ANC, Atmos, eARC, codecs, IP ratings, and more. Each page tells you what the term means, when it matters for a buy, and when you can safely ignore the badge.
Use these pages alongside Gadget Clash guides and product pages. Specs and app support change by region and firmware — confirm on the exact SKU before you buy.
Gadget Clash does not bench-test audio gear or formats. These pages decode marketing language so our guides are easier to use — honest, buyer-focused, not lab scores.
