Are the M100 ear buds waterproof?

Both the M100 earbuds and charging case are laboratory tested to IPX4 standards, which means you can use them in the rain and splash them with water. They are also sweat-proof, however, you cannot submerge them in water as this will cause damage to the product. We also do not recommend them for use in the shower, or anywhere where they could be subjected to heavy and consistent jets of water.
