This unit is equipped with hybrid noise cancellation, which features two microphones: a feedforward microphone, positioned outside the body, and a feedback microphone placed inside the body.

The feedforward and feedback microphones collect and detect ambient noise and residual noise in the ear canal with high accuracy, and feedback suppression allows you to enjoy deep bass even in noisy environments.

It uses a 12 mm large-diameter driver unit to produce powerful sound. In addition, by installing an acoustic chamber behind the driver unit and separating it from the battery and circuit board, which can adversely affect acoustics, this earbud is designed for XX series signature bass.

A tornado-shaped acoustic duct is placed in a separate acoustic chamber. Two tornadoes with opposite directions of rotation are used in succession to precisely control diaphragm movement for clear bass.

By incorporating the Extreme Deep Bass Port, bass reproduction is further enhanced. The bass boost can be controlled with an ON/OFF switch.

In addition to being IP55 waterproof* and dustproof*, the rubber case protects the earbuds from impact when dropped. Thanks to this TRIPLE PROOF body, it can be used with confidence outdoors, on the streets, or at other events.

*Applicable to the earbud body only.

The built-in high-capacity battery provides about 11 hours of continuous playback with noise cancellation on, and approximately 17 hours with it off. With a fully charged case, total playback extends up to 22 hours with noise cancellation on, and up to 34 hours with it off. The earbuds support instant charging, providing about 90 minutes of playback after just 10 minutes of charging when noise cancellation is off.

*Playback time may vary depending on usage conditions.
