3.1 7-Day Unopened Inspection Window
If an un-deployed digital white-noise machine, ambient sleep sound system, or un-molded noise-damping earplug set arrives with a verified manufacturing defect, displays transit damage, or deviates from your ordered technical model parameters, you may request a fresh exchange or credit replacement within 7 days of delivery. To qualify for a hardware verification claim, the items must be entirely unused, unpowered, free of surface smudges, and stored inside their original pristine retail packaging with all factory engineering tamper seals entirely untampered.
3.2 Personal Hygiene & Audio Component Exclusions
To maintain absolute sanitary security and biological cleanliness across our close-contact auditory hardware network, any earplugs, noise-blocking ear tips, or inner-ear device structures that have been unsealed from their primary vacuum-sealed protective cellophane shroud cannot be returned, exchanged, or refunded under any circumstances. Furthermore, customized firmware modifications or volume corporate hospitality fleet orders are strictly excluded from standard returns.
3.3 Quality Verification & Financial Replenishment
Once your acoustic hardware or audio cargo is safely received back at our central technical distribution hub, it undergoes a rigorous diagnostic inspection, signal output verification, and microscopic hygiene seal audit to confirm its original structural integrity. Approved claims are processed as immediate store wallet credits or direct financial replacements within 7-10 business days. Return logistics and secure courier arrangements for verified warehouse errors or shipment discrepancies will be fully managed and covered by NidraTech.
