Order acceptance controls
Quality control works when an inspector can identify the order version, select units by a written plan, run defined checks and record defects consistently. Build the checklist from the approved sample and purchase order, then separate critical, functional, cosmetic and packaging findings.
Direct answer
A wireless earbud QC checklist should verify model and color, housing and case appearance, accessory count, pairing, reconnection, left-right audio, controls, microphones, noise modes, charging contacts, case charging, indicators, reset behavior, printed materials and carton data. Define the sample plan, defect classes, test equipment, pass criteria and treatment of failures before inspection.
Use this before requesting a quotation
Name purchase order, model, color mix, artwork revision and approved sample. Define lot, sample selection, inspection level or other method with qualified quality support. State which checks apply to every sampled unit and which require smaller destructive or extended tests.
Check model and color against the order. Inspect housing seams, grille, microphone ports, charging contacts, hinge, lid alignment, connector, indicators, surface finish and markings. Use defect photos and size or location limits when cosmetic judgment could vary.
Use a controlled device and audio file. Check first pairing, reconnection, left and right output, channel balance by observation, single-ear use and recovery after returning to the case. Define what delay or failure requires retest or rejection.
Exercise the required tap and press functions on both earbuds. Place a defined call or recording check and cycle supported noise-control modes. Inspectors should record observable function, not make unsupported acoustic or voice-quality guarantees.
Confirm both earbuds seat and begin charging, the case accepts the specified cable, connector is secure and indicator behavior matches instructions. Extended charge, capacity and lifecycle tests need a separate method and appropriate equipment.
Count cable, ear tips, manual, warranty card and agreed extras. Match package model, color mark, barcode and language. Scan representative barcodes and verify no obsolete art or mixed accessory version enters the lot.
Count units and color assortment per carton, inspect carton condition and compare dimensions, weight and shipping marks with the order. Record short, over, mixed or damaged cartons separately from product defects.
For each failure, retain unit ID, photo or video, reproduction steps and defect class. Define containment, rework, replacement, reinspection and approval authority. A passed sample does not authorize unrecorded product or packaging changes.

Before you send the request
Examples include mixed versions, cosmetic defects, weak hinge or connector fit, one side not charging, pairing or reconnection failure, incorrect controls, missing accessories, wrong artwork and carton quantity errors. Defect limits must be defined for the order.
That depends on risk, process controls, cost and the agreed inspection plan. Some buyers use sampling while production lines may run broader functional checks. Define the plan before inspection with qualified quality support.
A short inspection can verify charging and basic operation, but not full capacity, aging or long-term consistency. Use a defined extended test when those outcomes matter.
Identify affected scope, stop uncontrolled dispatch, investigate cause, define rework or replacement, and perform the agreed reinspection. Keep approval authority and evidence in writing.
Keep the request specific
Use this page to structure the inspection, then add the approved model's exact functions, test steps and defect definitions. Formal sampling, electrical safety, radio, battery and acoustic testing should be designed or reviewed by qualified professionals.

MINJI derived this checklist from the controlled product, sample and order records needed to make an earbud inspection repeatable. It keeps short functional checks separate from extended or specialist testing and does not prescribe one sampling standard for every buyer.
