| IPX0 |
No protection against water ingress is claimed. |
Controlled indoor environments with minimal exposure to moisture. |
Office, desk-based, or dry-room purchasing programs. |
Not suitable for sweat, rain, splashes, or wet cleaning. |
Confirm the absence of an IP claim and review the manufacturer’s cleaning instructions. |
| IPX1 |
Protection against vertically falling water drops under specified test conditions. |
Very light overhead dripping in sheltered locations. |
Indoor facilities where occasional vertical moisture is possible. |
Does not cover angled rain, splashing, jets, or immersion. |
Request an IEC 60529 test report identifying the tested enclosure and configuration. |
| IPX2 |
Protection against vertically falling drops when the enclosure is tilted up to 15°. |
Light moisture from limited angles during indoor or sheltered use. |
Occasional handling in covered logistics, service, or retail areas. |
Not a rainproof, splashproof, or washable-headset rating. |
Check that the report states the complete headset or the exact rated enclosure. |
| IPX3 |
Protection against water sprayed at angles up to 60° from vertical. |
Light outdoor exposure and limited angled spray. |
Intermittent field work in mostly dry climates or protected areas. |
Does not guarantee protection from heavy rain, water jets, or submersion. |
Verify the spray-test method, test duration, and product sample identification. |
| IPX4 |
Protection against water splashes from any direction. |
Sweat, light rain, and incidental splashing during normal operation. |
Fitness, commuting, warehouse, education, and general outdoor use. |
Not rated for water jets, rinsing under a tap, swimming, or immersion. |
Request a current test report and confirm that charging ports and microphones were tested in the operating configuration. |
| IPX5 |
Protection against water projected by a nozzle from any direction. |
Heavy rain, stronger splashing, and environments requiring more frequent surface cleaning. |
Outdoor operations, industrial support, transport, and active workplace use. |
Water-jet protection does not automatically mean immersion protection. |
Confirm nozzle, flow, pressure, test time, orientation, and post-test functional results in the report. |
| IPX6 |
Protection against powerful water jets from any direction. |
Severe rain, powerful splashing, and demanding outdoor or industrial conditions. |
Utilities, construction support, marine-adjacent operations, and harsh weather exposure. |
IPX6 alone does not establish protection during immersion. |
Ask for an accredited laboratory report and confirm whether the rating applies to the headset, control unit, and charging accessories. |
| IPX7 |
Protection during temporary immersion in water under the specified test conditions, commonly up to 1 metre for 30 minutes. |
Accidental drops into water and short-duration immersion risk. |
Water-adjacent work, sports, and applications where temporary immersion is foreseeable. |
Does not automatically include protection against water jets; IPX5/IPX6 plus IPX7 may be stated when both tests are passed. |
Verify immersion depth, duration, temperature, preconditioning, and whether the headset must be dry before charging. |
| IPX8 |
Protection during continuous immersion at conditions specified by the manufacturer and agreed with the testing body. |
Specialized applications involving deeper or longer immersion than IPX7. |
Niche professional or water-focused applications with documented immersion requirements. |
The exact depth and duration are not fixed solely by the IPX8 code; confirm the declared conditions. |
Require the manufacturer’s declared IPX8 conditions, laboratory report, and after-use charging and maintenance instructions. |
| IPX9 |
Protection against high-pressure and high-temperature water jets according to the applicable test conditions. |
Very demanding washdown environments where high-temperature, high-pressure spray is expected. |
Specialized industrial, sanitation, or equipment-cleaning programs. |
Does not by itself define immersion performance; heat, detergents, salt, and chemicals require separate validation. |
Request the full test conditions, temperature and pressure limits, chemical-compatibility guidance, and product-specific report. |
