Marshall · Waterproof Earbuds & Cases
Headphone Case for Marshall Motif II True Wireless Active Noise-Canceling Earbuds Headphones, Hard
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes hard case, likely polycarbonate or EVA, with no water-repellent coating named. Water resistance on products like this usually comes from the material and its seals rather than a surface treatment. The brand has published no PFAS statement for it.

What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
BPA & bisphenols
If the case is polycarbonate, BPA can migrate under heat stress above 70C or prolonged contact with acidic substances. This is unlikely during normal storage of earbuds but possible if the case is left in a hot car or under direct sunlight for months.
Source, FDA ↗Mold or bacterial growth in sealed storage
If earbuds are placed in the case while damp or if the case is stored in high humidity without ventilation, trapped moisture can promote mold or bacterial growth on the earbuds themselves, not the case material. This is a usage issue, not a material hazard.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Microplastics
No reports of polycarbonate or EVA cases shedding microplastics into earbuds during normal use. Degradation only occurs after years of UV exposure or mechanical damage.
Source, EPA ↗Off-gassing from foam lining
EVA foam liners used in Marshall cases do not release volatile organic compounds (VOCs) under normal storage conditions. EVA is chemically stable and inert at room temperature.
The full breakdown
What it's made of and why it matters
Marshall's hard case is almost certainly polycarbonate or co-molded EVA foam with polycarbonate shell, both thermoplastics chosen for rigidity and shock absorption. Polycarbonate is lightweight and durable but can leach BPA under sustained heat or acidic conditions. EVA foam is inert and does not leach chemicals under normal storage conditions. Neither material off-gases significantly at room temperature, and the closed design means minimal vapor release into the earbuds themselves.
The brand's record and disclosure
Marshall does not publish detailed material safety disclosures or chemical testing summaries for accessories like cases. No PFAS statements have been issued by the brand. The company has no established history of safety recalls for hard cases or earbud storage products. Transparency remains limited compared to major consumer health-focused brands, but this is typical for audio accessory manufacturers.
How it compares in its category
Hard cases for earbuds are among lower concern product subcategories because they are not in direct contact with skin, not heated, and typically unlined or lined with inert foam. Marshall's offering is standard construction for premium audio brands. Alternatives (fabric pouches, silicone sleeves) offer no chemical advantage and less protection; rigid cases avoid moisture-trapping problems common in soft pouches.
If you buy it
Store the case at room temperature away from direct sunlight to prevent polycarbonate degradation over years. Do not leave earbuds in the case for extended periods in hot vehicles or high-humidity environments; allow airflow between uses. Inspect the case annually for cracks or cloudiness, which indicate material fatigue; replace if found. Wipe the interior with a dry microfiber cloth periodically to prevent dust accumulation inside the earbud charging area.
