Enclosure Design Accurately Reproduces What The Artist Intended


The open earbud shape, when worn, hangs in a hollow near the entrance of the ear. Since the open-type does not seal the ear canal, the user is less likely to feel a sense of their ear being sealed off. It is also convenient when users would like to enjoy calls or content and have awareness of sounds around them.


Canal earbuds are shaped to fit with a soft earpiece tip attached to the part that goes into the ear and seals the ear canal. This passive noise cancelling prevents most outside sounds from being heard.

True Sound

True Sound is created by Yamaha drawing on its unique know-how as a musical instrument manufacturer, and combining it with full focus on tonal balance, dynamics, and sound image. Our unique acoustic and electronics technology, including the adoption of newly developed speakers, delivers a profound musical experience that stirs your heart and your emotions - going beyond mere audio and making you feel as though you're right there in the presence of the artist.

Clear And Dynamic

The TW-EF3A provides clear vocals and human voices, making it easy to listen to over extended periods of time. The 13mm drivers fully express the energy and dynamism of the music.

Never Miss A Voice

Clear Voice is a function that lifts the bandwidth of the voice to make vocals easier to hear. In dialogue-driven content (e.g. dramas, news, movies, etc.), the voice becomes easier to hear without having to turn up the volume.

Calling That's Clearly Better

Convenient call function for both business and private use. You can also wear only one earbud and enjoy calls while being aware of sounds around you*.

Gaming Mode

Reduce the lag between sound and video when watching videos or playing games.

Activate Voice Assistants

Quickly activate Siri® or Google Assistant with the button.

Long Battery Life

With the charging case, it can be used for up to about 26 hours.

Water Resistant

With an IPX4 water-resistance rating, a little sweat or rain won’t harm these earbuds, making them perfect for exercise and life on the go.

Stay Connected

Equipped with technology that enables simultaneous L-R connection with devices for stable Bluetooth® connectivity.


*This product does not offer a function to convert stereo sound to monaural sound. The L and R sides on the earbuds operate different functions. When using only one earbud, use your Bluetooth device to operate controls like playback or talking on the phone.




Enjoy Listening At Low Volume

Yamaha's Listening Care allows you to fully enjoy music even at low volume levels. It compensates for high and low frequencies that are difficult to hear at low volume levels. It maintains the original sound range of the music even at low volume levels. It supports music listening at a volume that is easy on the ears.

Visit Yamaha's Listening Care website for more information.

Multipoint Connectivity

Connect two Bluetooth® devices simultaneously, such as a smartphone and a PC. When receiving an incoming call from one of them, take the call without switching devices.
