According to a report*1 issued by the World Health Organization (WHO) in 2019, roughly half of people aged 12-35 are at risk of hearing loss, and this number is expected to increase. The report also warns that listening to loud music using headphones for extended periods of time and being exposed to loud sounds from events such as live music causes increased risk of hearing loss.
Due to this important social issue, Yamaha has made Safe Listening*2 central to their new headphone development process to promote safe music listening with headphones. Since Yamaha re-entered the wireless headphones market in November 2019, all of Yamaha's wireless headphones and earbuds (including TW and YH series) are equipped with Yamaha's unique 'Listening Care' technology that makes intelligent equalization at any volume to support a safe music listening and without losing original musical balance.
