How We Recommend Testing Klakk
Test Klakk with the Mac, keyboard, headphones and applications you actually use. Keep the task constant, change one setting at a time, and record observations rather than assuming that sound improves focus or performance.
Five-minute test
Type the same short passage with Klakk off, then on at low volume. Include letters, Space, Enter, Backspace and normal shortcuts. Check timing, comfort and whether the generated sound stays in the intended audio output.
What the test cannot prove
A personal preference test does not prove productivity, medical, learning or error-rate benefits. Those claims require a suitable controlled study.
