  2. Insert the smaller end of the cable into the port on the left ear-cup of the headphones. Twist gently to engage the cable-locking mechanism.
  3. Insert the 3.5mm gold-plated jack into the headphone port of your audio device (smartphone, tablet, laptop, etc.). Ensure the extension ring on the jack allows for connection even with a protective case on your device.

Operation

Using the In-Line Remote and Microphone

The in-line remote, located on the cable, provides convenient control for Apple devices. Functionality may vary with other devices.

DJ Pivot Mechanism

The ear-cups can be rotated up to 180 degrees. This feature allows you to listen with one ear while remaining aware of your surroundings or engaging in conversations. To store the headphones, rotate the ear-cups inwards under the headband for a more compact form factor.
