Connecting via Bluetooth
To connect the product to a Bluetooth device, the product needs to pair (register) with the device.
Pairing a Bluetooth device
• Read the user manual for the Bluetooth device.
• Place the Bluetooth device within 1 m (3.3') of the product to perform pairing 
correctly.
• To confirm the progress of the pairing process, wear the product while performing 
this procedure and listen for the confirmation tone.
1.  Remove the headphones (L (left) and R (right)) from the charging case.
• The indicator lamps will flash in white.
2.  Use your Bluetooth device to begin the pairing process and search for the product.  
When your Bluetooth device finds the product, “ATH-CKS5TW” will be displayed on the device.
• For information about using your Bluetooth device, refer to the device’s user manual.
• This product may be displayed as "ATH-CKS5TW", "BLE_ATH-CKS5TW", or both. If both are displayed, select 
"ATH-CKS5TW". If only one is displayed, select that one.
3.  Select “ATH-CKS5TW” to pair the product and your Bluetooth device.
• Some devices may ask for a passkey. 
In this case, enter “0000”. The passkey may also be called a passcode, 
PIN code, PIN number, or password.
• The product sounds a confirmation tone when pairing is complete.
About pairing
When connecting a new Bluetooth device, you need to pair it with the product. Once the Bluetooth device and the 
product are paired, you do not need to pair them again. The product supports multipairing, in which a connection 
history is saved.
However, in the following cases you will need to pair again even if the Bluetooth device was paired once:
• If the product is deleted from the Bluetooth device’s connection history.
• If the product is sent out for repair.
• When switching to a Bluetooth device, you may not be able 
to pair because the previously connected Bluetooth device 
cannot be disconnected. In such cases, place the headphones 
into the charging case (with battery level remaining for the 
case) and press and hold (about 6 seconds) the multifunction 
button on the R (right) side. The indicator lamp lights in red. 
After lighting in red, the product will switch to the “searching 
for devices” state and you will be able to pair with your desired 
Bluetooth device.
