Second-generation headphones utilizing the third auditory pathway, "cartilage conduction*": These headphones employ a vibration structure that utilizes the cartilage conduction pathway in the ear. Because they don't block the ear canal, you can listen to music, audiobooks, and other audio content while still being aware of your surroundings. Unlike typical earphones, they don't go into the ear canal, making them less likely to cause ear pain even with prolonged use. Furthermore, they are hygienic as they prevent ear canal sweating. Equipped with a next-generation vibration driver for improved sound quality and maximum volume: These headphones feature a next-generation vibration driver (PAT.P) that offers improved sound quality and maximum volume compared to the previous model. Simply wear them against the cartilage called the tragus for high-quality listening and clear calls. The driver utilizes our proprietary "A.P.S.S" technology to prevent sound quality degradation due to external vibrations and suppress unpleasant vibrations during bass reproduction, resulting in a wide soundstage. This product is certified with the Japanese Technical Conformity Mark (frequency band: 2.4GHz band). It is the second-generation model of headphones that utilize the third auditory pathway, "cartilage conduction*". It employs a vibration structure that utilizes the cartilage conduction pathway in the ear. Because you can listen to sound without blocking the ear canal, you can safely listen to music, audiobooks, etc. while still being able to hear ambient sounds. Unlike typical earphones, it does not go into the ear canal, so it is less likely to cause ear pain even when used for long periods of time.
