Headphone Case for Marshall Motif II True Wireless Active Noise-Canceling Earbuds Headphones, Hard vs Geekria Shield Earbuds Case for Skullcandy EcoBuds, Dime 2 / 3 Smokin': which is safer?

Where these two actually differ

• We flag BPA leaching (polycarbonate) and Mold or bacterial growth in sealed storage on the Marshall 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 Marshall.
• The Marshall is Hard case, likely polycarbonate or EVA 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 Marshall grade, at 35% confidence against 72%, because it discloses less.
