Now TWS Bluetooth headsets in the industry have shown an explosive trend. There are dozens of different TWS Bluetooth headsets from large and small manufacturers. The design requirements, functional practicability, and wearing comfort of Bluetooth headsets are becoming more and more demanding. Stand out from the crowd and get the favor of customers, you must have a unique selling point of your own products, such as Bluetooth headsets with level 7 waterproof function. The waterproof rating of the binaural Bluetooth headset is divided into 0 to 8 grades, and the relevant criteria are as follows: 1, class 0 waterproof, which means that the related products are not waterproof; 2. Class 1 waterproof, which means that the product can prevent the intrusion of water droplets, and the water drops (such as condensate) falling perpendicular to the product angle will not cause damage to the product; Class 3 and 2 waterproof, which means that when the inclination angle between the product and the dripping water drops is within 15 °, the product can still prevent the intrusion of water drops, and the water drops will not damage the product Level 4 and 3 waterproof, which means that the product can prevent sprayed water from entering the product. The product is rainproof or prevents sprayed water from entering the product at an angle less than 60 degrees from the vertical. Level 5 and 4 waterproof, which means that the product has the function of preventing splashing water from entering, and can prevent water from splashing in all directions from entering the product; Level 6 and 5 waterproof, which means that the product can withstand the ingress of sprayed water into the product, and can prevent the intrusion of low-pressure water spray for 3 minutes or more; Levels 7 and 6 are waterproof, which means that the product can prevent water from entering the product under the conditions of large waves or a lot of water spraying. Waterproof grades 8 and 7 indicate that the product is still waterproof when the product is immersed in water up to 1 meter for 30 minutes; Waterproof grades 9 and 8 indicate that the product is also waterproof in water with a depth of more than 1 meter. The specific standards are specified by the manufacturer for each device. At present, the TWS Bluetooth headset on the market stays at the level of splash-proof and sweat-proof. If you want to wear waterproof swimming at level 7, you need to start structural waterproof design at the time of design, and cooperate with nanotechnology to waterproof. It is not recommended for consumers to wear TWS Bluetooth headsets for swimming. Since TWS headsets have no wires, they are easy to fall off during heavy movements, so it is not easy to find the headphones that are falling off at the bottom of the pool!
