Where these two actually differ

  • We flag Bioplastic thermal degradation and oligomer leaching, Microplastic fragmentation during use and disposal and Composting infrastructure dependency on the Pela and not on the Skullcandy.
  • We flag Microplastics from case degradation and Bacterial or mold growth in sealed case on the Skullcandy and not on the Pela.
  • The Pela is Plant-based bioplastic, compostable polymer where the Skullcandy is Plastic case, likely TPU or silicone blend, which is most of the difference in these two grades.

Both products run through the same public rubric, which covers materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
