Electronic products are currently closely related to life, and from a fashion perspective, Bluetooth sports headphones are the coolest and most noble pretentious artifacts today! Many manufacturers have launched waterproof Bluetooth headphones.The waterproof level of truly waterproof Bluetooth headsets is also divided into different levels.Among dustproof and waterproof, the highest dustproof level is level 6, and the highest waterproof level is level 8. The dustproof and waterproof level of Bluetooth headsets and Bluetooth speakers is generally IP67, with dustproof level 6 and waterproof level 7.So what should we do to meet the different IP levels of waterproof and dustproof Bluetooth headsets?How to determine whether a Bluetooth headset meets the IP67 waterproof rating?Today, Hirays will show you the detection methods and technical principles of waterproof testing of Bluetooth headsets.

The main levels of the waterproof part are 0-8, with level 0 meaning no protection; level 1 can eliminate the harmful effects of vertically falling water droplets; level 2 can block splashing water at 15 degrees in the vertical direction; level 3 can block splashing water at 60 degrees in the vertical direction; level 4 can eliminate the harmful effects of water droplets splashing from different directions; level 5 can eliminate the harmful effects of water jets from nozzles in all directions; level 6 can eliminate the harmful effects of powerful jets of water from nozzles in all directions.The top of level 7 is 0.15 from the water surface&- 1 meter, continuous for 30 minutes, performance is not affected, no water leakage; the top of level 8 is 1.5 from the water surface&-30 meters for 30 minutes continuously, the performance is not affected and there is no water leakage.

The birth of water Bluetooth headsets is inseparable from nano-waterproof coating, which is a colorless and transparent liquid product that is moisture-proof, moisture-proof, sweat-proof, acid-alkali-salt-proof and anti-corrosion.During the assembly process, soak the headset PCB board in the nano liquid (note: the headset manufacturer can add this process after all the PCB board components are soldered), soak the PCB board in the liquid for 3-5 seconds, take out the PCB board, let it dry naturally for 5-10 minutes, and then conduct a drip test.

Finally, the USB seams on the exterior are treated with waterproof interference fit, and a waterproof-level Bluetooth headset can be sold out of the factory.

The editor here recommends that you choose Bluetooth headsets based on actual conditions. The higher the waterproof level, the better the waterproof performance, and the higher the price.Of course, you can’t take Bluetooth headphones to bathe or swim at any time, after all, safety comes first!

For the detection method of Bluetooth headset waterproof test, first connect the product to be tested, such as Bluetooth headset, to Shenzhen Hiraysi's IP67 waterproof tester (air tightness tester).In this process, we need to make a fixture for the Bluetooth headset or product to conduct the IP67 waterproof test experiment of the Bluetooth headset.For specific column earphone waterproof testing procedures, precautions, and testing principles, please call the company’s official website for consultation.
