The IQbuds™ and IQbuds™ Boost are sweat proof and water resistant. They are suitable for exercising and exposure to light rain.  However, we do not recommend taking a shower or swimming while wearing your IQbuds™ or IQbuds™ Boost.
They have not been tested formally to determine their IP (Ingress Protection) rating, however, the internal electronic circuits are coated with NanoProof water protection technology, which claims protection equivalent to IPX7.
