Description

An open-ear experience that keeps your ears free
and your spirit uplifted as you enjoy what you love.

For over 60 years, Audio-Technica has been committed to delivering superior sound and pushing the boundaries of audio innovation.

In 2025, audio-technica introduce a new way to enjoy music without blocking your ears:

the ATH-AC5TW open-ear earbuds with air-conduction technology.

Now you can listen to what you want while staying fully engaged in your daily life.

Whether you're taking a walk while listening to an audiobook or doing chores while enjoying your favorite artist,

the open-ear design allows you to stay aware of your surroundings and connected to those around you.

It also enhances safety on the go, helping you stay alert to approaching cars or bicycles.

Full-Bodied Sound, Even While Multitasking
Rich audio reproduction with a large oval driver

The ATH-AC5TW features a large 17×12mm driver that makes full use of the limited acoustic space within the housing.

An acoustically engineered rear chamber and air-controlling duct work together to optimize driver movement, delivering rich and immersive sound.

●Includes Dual Bass Enhancement Technology

This technology combines two key elements: a digital processing algorithm that reinforces the low-frequency range,

and a dynamic EQ algorithm that preserves bass presence even at low volumes.

Together with Audio-Technica ’s proprietary sound tuning, this enables a well-balanced, full-bodied listening experience.

Smart Features That Support Your Work and Daily Life

● Multipoint Connectivity: Connect Two Bluetooth Devices Simultaneously

Easily pair with both your everyday smartphone and your work or school PC/tablet at the same time—no need to manually switch connections.

For example, while watching a livestream on your tablet, you can take an incoming call on your smartphone instantly without reconnecting.

● Clear Voice Pickup Even in Noisy Environments – Beamforming Microphones

Equipped with two compact high-performance MEMS (Micro Electro Mechanical Systems) microphones inside the earbuds.

Beamforming technology* focuses audio pickup toward your mouth, delivering your voice clearly even in loud surroundings.

*The microphones are directionally tuned to your mouth for precise voice capture, enhancing call quality.

● Water-Resistant Design to Protect Against Rain and Splashes

Certified with JIS IPX4* water resistance. Whether you're walking, working out, or camping,

you can use the earbuds without worry even if it rains or splashes occur.

Also great for kitchen or household chores near water.

*IPX4 means the device can withstand water splashes from any direction without harmful effects.

Not suitable for high-humidity environments like baths. Not fully waterproof.

● Single-Ear Use Supported
