A repeatable speech test for wholesale wireless microphone samples
Use a short controlled recording routine to catch connection, clothing-noise and channel mistakes before ordering a batch.
Make the test reproducible
Choose a quiet room, one speaking position and a short script. Record the device, firmware, app, microphone placement and gain settings alongside the clip. Keep an unprocessed reference recording; a social-platform upload may change the sound and hide the source of a problem. This is a practical acceptance routine, not a certified acoustic test.
Check the situations that create support calls
Test normal speech, a louder sentence, a quiet sentence and movement against clothing. If the ordered kit has two transmitters, identify each speaker aloud and confirm that both are present in the saved file. Repeat with the actual phone case or camera cable fitted, because a connection that works on a bare device may not seat correctly in the delivered setup.
- Listen for missing channels and intermittent gaps.
- Check that the recorded source is the external microphone.
- Retain the original files and setup photographs.
Agree what happens after a failure
Define who repeats the test, what evidence accompanies a return request and whether the issue follows the microphone or the host. Do not treat one successful sample as proof that every unit has been tested. Record the agreed batch sampling procedure and support territory in the quotation.
Common buyer questions
Frequently asked questions.
Should a sample test claim the manufacturer’s maximum range?+
No. A short local acceptance test establishes behavior in that setup only; it does not verify a maximum-range marketing claim.
