Setup

1. Unpacking: Carefully remove the headphones and all accessories from the packaging. Verify that all components listed in the "What's in the Box" section are present.
2. Connecting to Audio Source:
   • Locate the 3-meter long cable attached to the left earcup.
   • The cable terminates in a 3.5mm (1/8-inch) jack. Insert this jack into the headphone output of your audio device (e.g., smartphone, tablet, computer, MP3 player).
   • For devices with a 6.35mm (1/4-inch) headphone jack, attach the included 1/4-inch adapter to the 3.5mm jack. Ensure the adapter is securely screwed onto the jack for a stable connection.
   • The slim, tapered connector ensures compatibility with a wide range of devices, including various generations of iPhone and other portable audio players.
3. Wearing the Headphones:
   • Place the headphones over your ears. The self-adjusting headband will automatically conform to the shape of your head.
   • Ensure the ear pads fully enclose your ears for optimal sound isolation and comfort. The "L" and "R" markings on the earcups indicate the left and right channels, respectively.

Operation

Once connected, your AKG K 272 HD headphones are ready for use. Follow these guidelines for an optimal listening experience:

• Volume Control: Adjust the volume directly on your audio source. Start with a low volume and gradually increase it to a comfortable listening level. Avoid excessively high volumes to prevent hearing damage.
• Sound Quality: These headphones are designed to deliver a wide frequency response (16Hz to 28kHz) with minimal distortion. For the best audio fidelity, use high-quality audio files and sources.
• Comfort for Extended Use: The luxurious velvet ear pads and self-adjusting headband are designed for long listening sessions. If you experience discomfort, adjust the headphones slightly on your head.
• Sound Isolation: The closed-back design provides passive noise isolation, reducing ambient noise and preventing sound leakage. This makes them suitable for environments where you need to focus on your audio.

Maintenance

Proper care will extend the life and maintain the performance of your headphones:

• Cleaning Ear Pads: The velvet ear pads can be gently cleaned with a soft, dry cloth. For stubborn marks, a slightly damp cloth with mild soap can be used, but ensure the pads are completely dry before re-use. The ear pads are replaceable if they become worn.
• Cleaning the Headband and Housing: Wipe the headband and earcup housing with a soft, dry cloth. Avoid using harsh chemicals or abrasive cleaners.
• Cable Care: Avoid sharp bends or excessive pulling on the cable. Store the cable neatly when not in use to prevent tangles and damage.
• Storage: When not in use, store the headphones in a clean, dry place, preferably in the included carrying case, to protect them from dust and physical damage.
• Temperature and Humidity: Avoid exposing the headphones to extreme temperatures, high humidity, or direct sunlight for prolonged periods.

Troubleshooting

If you encounter issues with your AKG K 272 HD headphones, please refer to the following common solutions:

• No Sound:
  • Ensure the headphone jack is fully inserted into the audio source.
  • Check the volume level on your audio device; it might be muted or set too low.
  • Test the headphones with a different audio source to rule out a device issue.
  • Inspect the cable for any visible damage or kinks.
• Distorted Sound:
  • Reduce the volume on your audio source.
  • Ensure the audio file or source is not of low quality.
  • Check for proper connection of the 1/4-inch adapter if used.
• Sound Only in One Earcup:
  • Verify the headphone jack is fully inserted and not partially pulled out.
  • Rotate the jack slightly in the port to ensure good contact.
  • Test with another audio source to determine if the issue is with the headphones or the source device.

If the issue persists after trying these steps, please contact AKG customer support for further assistance.
