What Geekria Shield Earbuds Case Smokin' is made of, ingredients and materials
This case is EVA (ethylene-vinyl acetate) foam, a closed-cell elastomer commonly used in protective gear and phone cases. EVA is chemically stable at room temperature and does not leach into skin or food. The material is non-toxic when intact and does not off-gas formaldehyde or other volatile organics in normal conditions. No chemical additives are documented for this specific product model.
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.
Microplastics
Prolonged mechanical stress (compression, bending) can cause EVA foam to shed small particles. Risk is low for a protective case used normally, but high-friction or heat exposure may accelerate breakdown.
Source, EPA ↗Bacterial or mold growth in case cavity
Closed foam cases trap moisture if stored damp. Bacteria and mold can colonize the interior over weeks. Risk is minimized by air-drying the case and earbuds before storage.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Heavy metals
EVA foam is dyed during manufacturing, but no lead, cadmium, or antimony contamination has been reported for Geekria products. Testing data is unavailable.
Source, FDA ↗Volatile organic compound off-gassing
EVA does not off-gas formaldehyde or typical VOCs. Industrial-grade EVA may contain trace residual monomers, but published studies show negligible emission in finished cases at room temperature.
Skin irritation from dyes or additives
No allergic reactions or contact dermatitis reports exist for Geekria cases. EVA is hypoallergenic, though individuals with latex sensitivity rarely cross-react.
How is this PFAS grade calculated?
The brand's record and disclosure
Skullcandy is primarily an audio equipment manufacturer; Geekria is a third-party accessories brand with no public safety certifications or regulatory violations on record. Neither brand discloses material sourcing, chemical testing, or PFAS mitigation. No product recalls, heavy metal contamination reports, or formaldehyde complaints have been published for Geekria earbud cases.
How it compares in its category
Hard plastic or silicone cases often carry higher risk profiles (BPA, phthalates in plastics; silicone degradation). EVA foam is a safer-by-design alternative for protective cases. Most budget earbud cases lack safety certifications, so this product is typical in its transparency gap, not unusual.
If you buy it
Keep the case away from direct heat sources, as EVA can soften above 70C (158F), though it will not release harmful fumes. Wipe periodically with a damp cloth to prevent dust accumulation in the pocket seams. Replace if the foam becomes compressed or develops cracks, as structural integrity will decline. Store in a cool, dry location to extend foam life.
