Wireless Open-Ear Headphones

For more than 60 years since its establishment, Audio-Technica's commitment to delivering sound to its customers has driven its pursuit of innovation in sound technology. For 2025, we introduce the ATH-AC5TW air-conduction open-ear headphones, which take a new approach to keeping you aware of ambient sound by leaving the flow of air open.

Freely enjoy the audio you love while going about your daily life. For example, listen to an audio book while taking a walk, or enjoy your favorite artist while doing housework. Since your ears are left uncovered, you can still hear surrounding sounds, including the people around you. These headphones are also safe to use when you are out and about, letting you stay aware of approaching cars and bicycles.
