Sophisticated, modern design

Harman Kardon NI headphones offer high-tech performance wrapped in an elegant package and interface. With its blend of aluminum and black, the NIs’ design and function complement Apple products while reinforcing the sophisticated elegance of the Harman Kardon brand.

Optimized driver system

High-performance 3/8-inch (9-millimeter) drivers generate an excellent frequency response (20Hz – 20kHz), wide dynamic range and high sound-pressure levels. They also produce accurate bass at any volume level.

Sonic clarity and accuracy even at low volume levels

The NIs’ acoustic engineering and passive noise-reduction mean that you can hear music and other audio content clearly at low volume levels. So you can enjoy all the music definition without all the volume – and that’s safer for your ears.

Black one-piece housing

The rectangular housing complements the shape of companion iPhone, iPad and iPod products, while the beveled surface underneath the housing enhances in-ear comfort.

Silicone sleeves

Three pairs of sleeves (small, medium and large) are included. The choice of size ensures maximum comfort – and minimum ambient noise – in the ear canal.

Apple three-button remote with built-in microphone

Made specifically for use with iPhone and iPod, the streamlined remote offers familiar controls for audio playback controls and phone calls.

Heavy cable and durable plug

The cable on the NI headphones features a metal plug and an elastomer-coated cable that resists tangling. High-quality materials help the cable and plug last longer.

Carrying case

Beautiful sound is worth protecting. Harman Kardon NI headphones come with a carrying case that keeps the silicone sleeves from getting lost and reduces cable tangling.

NI is rated 3.4146 out of 5 by 164.
Rated 3 out of 5 by from Good sound, Bad housing design I am satisfied (just) with its sound, especially considering its size, but I might not recommend this to my friends. 1. Sound: (4.5/5) Last night, I compared with some other old headphones/earphones I have, AKG K99 (over-the-ear), Sennheiser PXC 250 (on-ear, noise cancelling on), and Sennheiser CX-380 (in-ear-canal), which are in a similar price range (street price) roughly. I used Nexus 4 and an MP3 player as its sound source, because I guess most people use this for outdoor use. HK NI has pretty good mid and high, but when it comes to bass, there is no oomph, which can be expected naturally from its small-sized unit. If the included ear-tips can give you a perfect fit, you might feel a little bit differently. Overall, I felt its sound was quite similar to AKG K99's, well balanced across the entire frequency range with slight focus on upper-mid and high. This might be due to the fact that AKG got involved in its design. For me, AKG K99 was the best among them, PXC250 was a little bit better than HK NI, and CX380 was a lot worse than HK NI. Considering its small size, it provides quite descent sound, but if you are looking for bass-heavy headphones, HK NI is clearly not for you. 2. Design: (1/5) I guess HK designers wanted to maintain an identity across the entire headphone line up. Rectangular design looks okay on its big brother BT or CL, but personally I think they should have used a different shape for in-ear headphone design. Rectangular ones simply do not fit into outer ear comfortably. It is not painful to wear HK NI, but not as comfortable as CX380. In addition, pushing the ear-tips in is okay, but removing them is quite uncomfortable because of its small, rectangular design. I usually use middle ear-tips, but with this one, I needed to use large ones in order to alleviate its uncomfortable fit. The wire is quite curly and stiff: even after around 10 days of use, it stays the same. 3. Three-button control: (4/5) HK NI is for iPod/iPhone/iPad. So, only one button in the middle works correctly with Nexus 4: one short click for play/pause, one long click for Google now, two clicks for skip forward, and three clicks for skip backward. Google now works quite well with the microphone on the wire. I didn't test call connection or termination with this. In short, HK NI gives you quite well balanced sound, but because of the not-so-ergonomic rectangular design, it is a little bit uncomfortable to wear.

Rated 4 out of 5 by from Buy these on sale; great phone headphones When you first use these headphones they sound bland. After 40 hours of so of getting the headphones broken in with white noise they start budding (pun intended) and start sounding like HK quality-- so don't judge them right away. I got these for a steal for $18.00 a pair (here on the HK website), so I can't complain!--this is why I had my value maxed out on my review. Cons: Bass is weak -- but the bass doesn't sound muddy, so raise up the volume, cord length could have been just a bit longer for my liking, price is expensive--unless on sale Pros: the 3 different sized earbuds will fit anyone, the cord doesn't tangle easy, very good sound EQ balance, great noise isolation, awesome phone mic and sound

Rated 5 out of 5 by from Amazing Sound Way better than Bose headaphones, I did a side by side test. These blow Bose out of the water. Buy them! You won't regret it.

Rated 1 out of 5 by from Poor audio quality These earphones remind of listening to audio through a tin can, except slightly more comfortable. You could do worse than these set of earphones, I suppose, since these at the very least have a nice and sturdy cable, but there is no overlooking the pathetic audio quality.

Rated 1 out of 5 by from Thin Sound I read many reviews that complained about the bass on these headphones. In the current culture where head-rattling bass seems to be the prime criteria for audio equipment, I chose to ignore all these warnings, figuring I wasn't in that crowd. Should have listened. These things are so high frequency sensitive and so bass excluding as to be unlistenable. Without significant equalization the sound of a snare or trumpet will pierce your head like an icepick while any bass drum or guitar is completely gone.

Rated 1 out of 5 by from Bad fitting and design Looking at the price and brand I bought these headphones thinking they might be comparable to likes of Bose, but realized they are not as good as skull candy when it comes to fitting in the ear.
