Flip 3 Splashproof Portable Speaker Replacement Usb Charging Cable Lead vs A610 Universal Waterproof Float Case: which is safer?

Where these two actually differ

• We flag Insulation degradation and electrical hazard, Metal connector corrosion and poor contact and Phthalates in PVC outer sheathing on the JBL and not on the Spigen.
• We flag TPE material degradation, Microplastic shedding and PFAS in waterproofing coatings on the Spigen and not on the JBL.
• The JBL is USB cable, likely rubber and copper where the Spigen is TPE (thermoplastic elastomer) with waterproof sealing, 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 Spigen grade, at 42% confidence against 72%, because it discloses less.
