Lightweight and comfortable, these in-ear headphones deliver detailed, studio-quality sound.
"A Clear Step Up"
"Taken as a whole, K391 NC is a very good noise-canceling earphone option," reports Jeremy Horwitz in his iLounge.com post for March 18, 2013. "Between the nice industrial design, clean sound, and very welcome rechargeable battery, it represents a clear step up from low-end noise-canceling earphones…"
Noisy airplane cabins. Crowded subway cars. Bustling plazas. Busy coffeehouses. You never know what kinds of ambient noise will compromise your ability to fully appreciate AKG sound. With K391 NC headphones, you don't have to accommodate noise, you can eliminate it. These in-ear headphones employ active noise-canceling technology that strips away the outside sounds and leaves you with nothing but powerful, detailed AKG sound. The battery that powers the noise canceling lasts up to 40 hours and can be easily recharged via a USB port.
The K391 NC comes with a flight adapter that takes the sound quality of in-flight movies and audio programming to new heights. The closed-back design keeps your music from leaking out and distracting others, while an in-line microphone lets you answer a call as easily as listening to a song.
Famous AKG Sound Quality
For over 65 years, AKG Acoustics has been a leader at creating studio sound in headphones. AKG holds over 1,400 patents for its groundbreaking products and has received two technical GRAMMY® Awards (in 2010 and 2005) for sound innovation.
Active Noise Cancellation
Tiny microphones on the outside of each of the earpieces detect the difference between the sound the K391 NC 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 K391 NC 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.
K391 NC headphones keep music in and noise out. Their closed-back design helps attenuate ambient noise while preventing the sounds that you're hearing from leaking out.
In-Line Microphone and Remote Control
K391 NC 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. K391 NC 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.
When it comes to audio quality, courtesy airline earphones aren't much of a courtesy. K391 NC 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.
