  Key Features

  Famous AKG sound quality

  For over 65 years, AKG Acoustics has been the leader in creating studio sound in headphones. AKG holds over 1,400 patents for their groundbreaking products; and two TECHNICAL GRAMMY Awards (2010, 2005) for sound innovation.

  Active noise cancellation

  Tiny microphones on the outside of each of the earpieces detect the difference between the sound the K391NC headphones are delivering and the sound coming from the world around. Noise-canceling technology then creates exact waveforms to negate the unwanted noise, so that all you hear is the desired music or audio.

  40-hour play time

  The battery used to power the active noise cancellation in the K391NC headphones will last up to 40 hours. And the battery is easily rechargeable via a USB port, making recharging convenient in airports, planes and other locations with USB recharging stations. Two cables for different phone models are included.

  Closed-back design

  K391NC headphones keep music in and noise out. Their closed-back design helps attenuate ambient noise while also preventing the sounds that you are hearing from leaking out.

  In-line microphone and remote control

  K391NC headphones have an in-line microphone, so you can make calls that are every bit as crisp and noise-free as the music you listen to on your smartphone. The mic is ideal for FaceTime, Skype and virtually any application requiring a microphone. The three-button remote lets you control the playback functions and volume from iPhone and iPad devices, as well as Apple laptops and desktop computers.

  Premium hard case for iPhone

  Your iPhone is an on-the-go audio source. AKG K391NC headphones come with a premium hard case to protect it from all the bangs and bumps of an active day. That way, your iPhone is as protected from the outside world as your ears are from outside noise.

  Flight adapter

  When it comes to audio quality, courtesy airline earphones are not much of a courtesy. K391NC headphones come with an adapter that makes them compatible with nearly every airline, so that you can enjoy in-flight entertainment with AKG sound quality.
