Many neckband or behind-the-head headphones are designed to resist sweat or water splashes with at least an IPX4 rating, making them perfect for active lifestyles, even worn during workouts or traveling/commutes.

But ensure to look for headphones offering a minimum IPX4 rating to protect against moisture, and a comfortable & secure fit for durability and longevity.
