Yamaha TW-EF3A True Wireless Earbuds


***Stock ETA April 2024***

TW-EF3A “open-ear” earbuds are designed to nest in the outer ear without silicon ear tips.
Their sound signature makes vocals and human voices sound clear, while a wide range of content can be enjoyed. The 13mm driver moves a large amount of air in order to express energy and dynamism. Made from titanium plating, its central inverted dome helps hone accurate reproduction of high frequencies.

The TW-EF3A provides multipoint connectivity so two Bluetooth devices can be simultaneously connected. Meaning you can enjoy a movie on your tablet and receive a call on your smartphone, then easily answer the call without having to manually switch device. Plus you can choose to wear only one earbud and take calls while being more alert to your surroundings.

Available on back-order



True Sound – Extraordinary realism, detail and clarity

Clear Voice – 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.

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.

Convenient 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.

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.*1

Gaming Mode – Reduce the lag between sound and video when watching videos or playing games.*2

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.
