Shield Earbuds Case vs Geekria Shield Earbuds Case for Skullcandy EcoBuds, Dime 2 / 3 Smokin': which is safer?

Where these two actually differ

• We flag BPA or other bisphenols in polycarbonate, Microplastics shedding from surface wear and Mold or bacterial growth in crevices on the Geekria and not on the Skullcandy.
• We flag Microplastics or foam degradation fragments and Bacterial or mold growth in case cavity on the Skullcandy and not on the Geekria.
• The Geekria is plastic hard case, material composition not disclosed where the Skullcandy is EVA foam case shell, which is most of the difference in these two grades.
• These two are level, close enough that price and fit should decide it rather than our grade.
• We are less certain about the Geekria grade, at 45% confidence against 72%, because it discloses less.
