On July 10th, NTT Sonority held a seminar on how to deal with stuffy earbuds.
Since the corona disaster, remote work has become popular, and the opportunities to use earphones at work have increased. According to the company’s research, many earphone users are concerned about the stuffiness of their ears.
In addition, cases of otitis externa are increasing among users who use earphones for a long time.
Toshihiko Oba, director of Keiyu Ginza Clinic, explained the risk of stuffy ears and otitis externa due to wearing closed-type earphones for a long time. He said, “The number of patients has tripled compared to before the pandemic. Most of the patients have otitis externa. The problem is that wearing earphones makes the inside of the ears hot and humid.” On top of that, he acknowledges that “closed-type earphones make the inside of the ear hot and humid, so open-ear types are better.”
NTT Sonority sells the “nwm MBE001,” a wireless personal ear speaker that minimizes sound leakage despite its open ears. Equipped with the world’s first PSZ (personalized sound zone) technology to minimize sound leakage. It is an earphone that allows you to hear the surrounding sounds and voices while enjoying music.
