ワイヤレスイヤホン

• Reading: ワイヤレスイヤホン
• Romaji: waiyaresu iyahon
• Pronunciation: /wa.i.ya.re.su i.ya.ho.n/

Meaning

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.

Examples

1. 電車の中でワイヤレスイヤホンつけてる人ばっかり。 Everyone on the train is wearing wireless earbuds.
2. ワイヤレスイヤホン無くして焦ったけど充電ケースに入ってた。 I panicked when I thought I lost my wireless earbuds, but they were in the charging case.
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。 Even cheap wireless earbuds come with noise canceling these days.
