Setup
- Attach the Cable: Select either the 3-meter straight cable or the 5-meter coiled cable. Connect the mini XLR end of the cable to the input jack located on the left earcup of the headphones. Ensure it clicks securely into place.
- Connect to Audio Source: Plug the 3.5mm jack end of the cable into your audio device (e.g., audio interface, mixer, computer, smartphone). If your audio device requires a 1/4-inch connection, screw on the included 1/4-inch adapter to the 3.5mm jack.

Operating Instructions
Wearing the Headphones
The K271 MKII features a self-adjusting headband designed for optimal fit and comfort during long listening sessions. Simply place the headphones on your head; the headband will automatically adjust to your size.

Auto-Mute Feature
The K271 MKII includes an auto-mute switch integrated into the headband. When the headphones are removed from your head, the audio signal is automatically muted. This prevents unwanted sound leakage and conserves power if connected to certain devices. The audio resumes when the headphones are placed back on your head.

Closed-Back Design and Sound Isolation
These headphones feature an advanced closed-back design, providing high noise insulation. This is particularly beneficial in studio environments to minimize signal bleeding into microphones during recording, and for maximum isolation in live mixing applications.

Maintenance
Cleaning
- Wipe the headphones with a soft, dry cloth.
- Do not use liquid cleaners or solvents.
- For ear pads, follow specific cleaning instructions provided by AKG or use a slightly damp cloth and allow to air dry completely before reattaching.
Cable Replacement
The detachable cable with a professional mini XLR connector allows for easy replacement. To detach, gently pull back the locking mechanism on the mini XLR connector and pull the cable out. To attach a new cable, align the connector and push until it clicks securely.
Ear Pad Replacement
Ear pads can be replaced for hygiene or comfort. Gently peel off the old ear pad from the earcup. Align the new ear pad with the earcup's rim and carefully work it around the edge until it is fully seated and secure.
