CT12 lets you listen to music for 12 hours of continuous playback in dual mode.
80 hours of long playback time when playback in Single mode.

Powerful Hi-Fi Stereo Sound with 9mm Drivers
Sound by COWON
COWON CT12's large 9mm drivers offer more balanced Hi-Fi stereo sound than 6mm drivers,
delivering rich middle-to-low frequencies and clear high-frequency sound.
Left and Right Earphones Connected Simultaneously
with Auto Master & Slave Technology
The Auto Master & Slave technology applied in COWON CT12 provides enhanced user convenience through an individual wireless connection of the left and right earphones where both earphones work independently without affecting each other even when you turn off or turn on one of them in Dual mode. In addition, a more stable connection is achieved through the simultaneous connection of the left and right earphones instead of a main-to-sub type connection.

Simultaneous Connection
Bluetooth 5.0
for a Faster, Farther Wireless Connection
Bluetooth 5.0 is twice as fast as the previous iteration and offers four times the range and eight times the data bandwidth.
The double transmission speed reduces transmission time and battery consumption,
and quadruple range allows seamless connections up to 40 meters in low-power mode.
Seamless Automation Just remove or insert the COWON CT12 earphones from or in the cradle and turn them on or off, respectively.
When powered on, it conveniently pairs automatically with your audio device.
* Auto-pairing is available once the initial device pairing has been completed.
The Right Touch Sensitivity for Your Earphones
Optimal Touch Control
The convenient multi-function button handles various functions such as music playback, calls, speech recognition and volume control.
The touch response has been optimized for the user environment to minimize accidental touching and unintended operations.
One-Press Smart Speech Recognition
Google / Siri Activation
To use a speech recognition feature such as Google Assistant or Siri, touch the earphone button 3 times. Smart speech recognition is just at the tip of your fingertips.
Dual Mode and Single Mode for Listening Freedom With the COWON CT12, you can freely choose between Dual Mode for listening to music or Single Mode for listening to podcasts or audiobooks. You can use your earphones in a safer manner by using just one earphone and to avoid potentially-dangerous situations while driving or walking having external sounds completely blocked out.

* Remove both the left and right earphones from the charging cradle for use in Dual Mode,
or only remove one earphone for use in Single mode.
* Putting one earphone in the charging cradle while in Dual mode does not disconnect the other earphone in use.

High Sensitivity Antenna and Dual Microphones for Clear Call Call audio in both left and right channels. Because each earphone is equipped with high sensitivity antenna and its own dual microphone, calls can be made through either earphone when using Single Mode.
Dual microphone delivers crystal clear voice.
Single Mode In Single Mode, each earphone will
output sound with both microphones
enabled for use.
Dual Mode In Dual mode, the microphone of the earphone removed from the cradle first will be enabled. Removing L and R earphones from the cradle at the same time enables the "R" microphone.
Charging, and Storage All in One
Double Magnetic Charging Cradle
When storing the earphones, simply place the earphones near the cradle to magnetically install them in the correct orientation and
begin recharging automatically. The double magnetic charging cradle uses magnets to prevent the unintentional loss of your earphones.

* Please charge the charging cradle periodically. When the cradle battery is discharged,
the earphone units may turn-on instead of being charged, causing the earphone to be discharged.
