The term “waterproof” is for products that can withstand submersion (IPX7 or IPX8 rating). The term “water-resistant” describes earbuds that can resist splashes and sprays of water to some degree (IPX6 or lower). Be aware that no earbuds are truly waterproof. Too much pressure or prolonged exposure to water will damage earbuds even if they have an IPX8 rating. Further, water-resistant ratings actually degrade over time and with regular use. Extreme heat and cold, and even dropping your earbuds can compromise their water resistance.
