On June 10, a college student in Zhengzhou, Henan Province posted a video on social media saying that the wireless Bluetooth headset he was wearing exploded in his ear while sleeping at night. The reporter contacted the student involved, Sun. Sun said that at about 1 a.m. on the day of the incident, after the lights in the dormitory were turned off, he was wearing headphones to watch videos, but the headphones suddenly exploded. Fortunately, no serious injuries were caused.
Classmate Sun recalled that there were no signs of abnormal noise or heat before the earphone exploded. The sound was so loud when it exploded that his roommate mistakenly thought it was a dropped cell phone. After the explosion, he experienced mild tinnitus and localized burning sensation in his ears. The next morning, he went to the hospital for a check-up. The results showed that his eardrums were intact and his tinnitus symptoms had disappeared. He only had a slight feeling of blockage in his ears and his hearing was not affected.
According to Sun, the headphones were purchased after seeing recommendations from others on the Internet. They have been used normally for more than a year and have never had any abnormalities before. He does not use headphones frequently on a daily basis. He only uses them for a short time after the lights are turned off in the dormitory. On the day of the incident, he only wore them briefly before going to bed. Sun said that the headphones that exploded were not low-priced "off-brand" products. They were purchased for about 70 yuan each and were sold on common e-commerce platforms, with sales reaching millions.
Reporters searched social platforms and found that posts about the explosion of wireless Bluetooth headsets are not uncommon, ranging from well-known brands to cheap no-name brands. The reporter then consulted a number of wireless Bluetooth headset merchants at different price points, and they all said that their products did not have the risk of explosion. Some merchants promised to provide replacement warranty services, with the warranty period ranging from one to three years.
Some merchants pointed out that the hidden dangers of wireless Bluetooth headset lithium batteries mostly come from inferior accessories, human damage or illegal charging. As long as the earphones are compliant products purchased from regular channels, they will basically not explode during normal daily wearing and charging.
Afterwards, classmate Sun contacted the headphone manufacturer. The other party requires that the faulty headphones be sent back for testing. If it is determined to be a product problem, the medical examination costs can be borne. Sun said that he does not plan to pursue further accountability in the future, so he will not disclose the headphone manufacturer information to the outside world.
