■High-quality music playback and voice calls
Equipped with a large-diameter 13mm dynamic driver, you can enjoy deep bass and clear, loss-free surround sound.
In addition, it is equipped with a dual microphone noise reduction system using proprietary technology.
By suppressing surrounding noise and accurately capturing people's voices, you can transmit clear and realistic audio to the other party.

■Fast and stable connection
Adopts Bluetooth 5.3, allows you to connect iPhone, Android, Windows, iOS, etc. within a range of 10 meters.
High-speed transmission and stable connections are ensured with various Bluetooth-enabled electronic devices, with almost no delays or skipping.
Pairing with the device to be connected is done only once for the first time, and from the second time onward, the pairing will be done automatically by simply opening the charging case and taking out the earphones.

■Accurate touch sensor operation
Since the touch area can be clearly recognized by the sensation of a fingertip, unintentional malfunctions that are common with touch sensors that only touch lightly can be avoided.
