Active noise cancellation is the biggest selling point of wireless headphones, but for those exercise lovers, waterproof rating can be their top priority. OnePlus Buds Pro, the company’s first top-tier earbuds will meet your need in this aspect. It is unprecedentedly waterproof and dustproof, achieving a IP55 waterproof rating, a relatively high score in the headphone list.

The IP rating stands for “Ingress Protection” rating, an international standard created by the International Electronical Commission (IEC), under the standard 60529. It provide numbers of clear definitions about how exactly “water-resistant” or “dust-proof” a device is. There are two digits following “IP”, in which the first one stands for the degree of protection against the intrusion of solid objects (like dust, body parts and fingers), and the second one is the same protection but against water.

Most wireless headphones only offer protection against water, such as Samsung Galaxy Buds Pro (IPX7) and Apple AirPods Pro (IPX4). OnePlus Buds Pro has IP55, meaning that it is dust-protected and can withstand water projected by a nozzle (6.3mm) from any direction. You’re totally free to use them while sweating or in light rain, let alone regular workouts or running. Can you use them for swimming, then? As the chart shows, they have to reach at least “7” for the liquid digit in order for you to swim with them 1m under water under defined conditions of pressure and time.
Another possible issue is the weak streaming signal due to long distance from audio source, so it is not recommended to use headphones underwater, unless it is the Bluetooth products specialized for swimming, such as APEKS Bluetooth Headphones, and Kurdene Wireless Earbuds.
OnePlus Pro Buds charging case also gets an IPX4 waterproof rating, meaning that water splashing against the enclosure from any direction shall have no harmful effect. This is another added bonus for outdoor use.
