1, just buy the new headset as far as possible to avoid large volume use: Horn diaphragm factory is more hard, generally used dozens of hours after the best state, if just buy headphones on the use of large volume to listen to the song, the diaphragm is prone to damage deformation, so try not to buy the headset with a large volume for a long time to listen to the song.

2, as far as possible to avoid collisions: horn diaphragm is a more sophisticated things, violent collision will cause internal parts loose or damaged, so that the diaphragm deformation, so in order to protect the horn diaphragm should try to avoid the headset bump and drop.

3, pay attention to the temperature: now the material variety of diaphragm, and the heat resistance of each material is not the same, in the high temperature conditions, the diaphragm is prone to deformation, so the Bluetooth headset should avoid direct sunlight, especially in the sun for a long time use. 

4, away from water, corrosive chemicals, such as: the most used horn diaphragm is a metal material, of course, there are also some biological vibration film, paper film, no matter what kind of diaphragm, water or corrosive liquids are prone to damage
