Very High Sensitivity Laser Embedded Antenna
and Cutting-Edge Airoha Chip
COWON CK11 Pro is equipped with a customized LDS(Laser Direct Structuring) antenna, exclusively designed and laser-shaped for CK11 Pro. There is no interruption when on the move, whether on a subway or bus, and seamless sound is maintained in open spaces for up to 40 meters.
Left and Right Earphones Connected Simultaneously with MCSync Technology The Airoha chip with MCSync technology applied in CK11 Pro 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.
2600mAh High Capacity Cradle: Get a month's Use from a Single Charge & Use as a Backup Battery The capacity of 2600mAh is enough to recharge the earphones more than 10 times. With this high-capacity charging cradle, one full charge lasts for a month in Dual mode. You can also use the cradle as a backup battery. It's very useful when you need to charge your smartphone.
Digital Battery Indicator Check the battery level at a glance. The battery levels of the charging cradle and the left and right earphones are displayed on the LED display.
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.
Complete the Pairing just by Opening the Cradle Lid When the lid of the charging cradle is opened, the power is automatically turned on and paired for a more prompt
and convenient wireless connection.

* Auto-pairing is available once the initial device pairing has been completed.
One Button to Control Them All
One-click Volume Control Feature
All earphone controls are available via a single button. The convenient multi-function button handles various functions such as power on/off, Bluetooth pairing, music playback, and calls. COWON CK11 Pro also features a volume control that conveniently allows you to adjust the volume by clicking the button on your earphones without taking out your smartphone.
Smart Speech Recognition
Google / Siri Activation
To use a speech recognition feature such as Google Assistant or
Siri, press 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 CK11 Pro, 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.
Call Audio in Both Channels, Dual Microphones & Noise Reduction Technology It enables you to make your phone calls with one side of your earphone. Because each earphone is equipped with its own dual microphone, calls can be made through either earphone when using Single Mode.
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

magnetically install them in the correct orientation and begin recharging automatically.
