ワイヤレスイヤホン

• 読み: ワイヤレスイヤホン
• ローマ字: waiyaresu iyahon
• 発音: /wa.i.ya.re.su i.ya.ho.n/

意味

Wireless earbuds; AirPods and similar devices that are now practically universal among young Japanese commuters.

ワイヤレスイヤホン became ubiquitous on Japanese trains and streets following the removal of the headphone jack from smartphones and the launch of AirPods in 2016. The term is often shortened to ワイヤレス in context. True wireless earbuds (両耳完全ワイヤレス) from Apple, Sony, and Anker dominate the market. Their use on trains, during study sessions, and at work is so widespread it prompted social debate about social isolation and safe commuting.

例文

1. 電車の中でワイヤレスイヤホンつけてる人ばっかり。

3. 安いワイヤレスイヤホンでもノイキャンついてるの増えてきたよね。
