Lab Notes Promise
Our baseline lab stimulus uses a 20–20k Hz sweep, anchored with a 1 kHz reference tone, captured at 48 kHz, 24-bit. Those numbers aren't decoration—they're guardrails that keep comparisons honest across different headphones, earbuds, and gaming headsets. We publish what we do, show the receipts, and keep the language readable so you can trust the process behind every verdict.
