Marshall Motif II True Wireless ANC Leather Case
Leather case with minimal PFAS risk; brand silent on treatment.
Marshall does not disclose water or stain treatments on this leather case. Untreated leather poses lower PFAS concern, though treated leather may contain water-repellent coating chemicals.

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.
Heavy metals
Leather tanning residues (chromium, lead) are present in many finished leathers but transfer to skin via incidental contact is typically low. Marshall does not disclose tanning method or heavy-metal testing for this case, so presence cannot be ruled out.
Source, FDA ↗Synthetic dyes and colorants
Leather dyes can include azo dyes or acid dyes that may cause contact dermatitis in sensitive individuals. No specific allergen information is available for the Motif II case; the black leather colorant is not documented.
Coating and waterproofing treatments
Leather finishes often include polyurethane or wax-based water repellents; some older leather treatments included formaldehyde-releasing resins. No coating chemistry is disclosed for this case, and modern finishes are typically low-volatility.
Off-gassing and odor from fresh leather
New leather cases may emit a characteristic odor from residual solvents and tanning agents for the first few days to weeks. This is not hazardous in typical use but can be unpleasant in confined spaces.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Microparticle shedding from surface degradation
Leather does not shed microplastics, but aged or poor-quality leather can flake. No reported flaking issues exist for Marshall Motif II cases; this is a low probability for a protective accessory.
The full breakdown
What it's made of and why it matters
The Motif II case is leather, a natural material that requires tanning and finishing to become wearable. Leather tanning traditionally uses chromium salts or vegetable tannins, and finished leather can carry residual heavy metals (chromium, lead) from processing, along with synthetic dyes and waterproofing treatments. Unlike ceramics or non-stick cookware, a leather case does not release chemicals into food or inhalable fumes during normal use, making direct exposure pathways minimal. The main concern is skin contact with dyes and finishes during repeated handling and storage of the earbuds.
The brand's record and disclosure
Marshall does not publicly disclose leather sourcing, tanning method, or chemical certifications for this case. The brand has no published PFAS position or materials transparency reports. No product-specific recalls or safety controversies have been reported for Marshall leather cases. Absence of disclosure does not indicate hazard, but it reflects a common industry practice of minimal chemical communication at the consumer level.
How it compares in its category
Leather cases are generally lower-risk than synthetic leather alternatives, which may shed microplastics or contain plasticizer chemicals. However, leather sourcing varies widely; some tanneries use stricter heavy-metal controls than others. A Marshall leather case sits in the mainstream segment with no special certifications (e.g., no Leather Working Group rating disclosed), placing it typical for consumer electronics accessories. Direct comparison is difficult because most competitors offer no more chemical transparency.
If you buy it
Wipe the case with a slightly damp cloth on arrival to remove surface dust and loose dye residue if any. Avoid prolonged contact with skin in very warm conditions to minimize potential dye transfer. Store in a cool, dry place; leather can degrade and crack if exposed to extreme heat or humidity, which may release particulates. No special maintenance is needed beyond occasional gentle cleaning; replace if leather visibly deteriorates or flakes.
