Cross-border shipping and diverse usage conditions (e.g., humid climates in Southeast Asia, dry winters in North America) require robust build quality:

• Materials : Earcups and headbands often use ABS plastic (impact-resistant) and protein leather (skin-friendly, sweat-resistant); some high-end models add metal hinges to prevent breakage from frequent folding.
• Protection ratings : Most have an IPX4 waterproof/sweatproof rating, resisting splashes from rain or sweat during intense gaming sessions—ideal for gamers in tropical regions or those who game while exercising lightly.
