Sony NC200D Side Shot

Key Features

Digital Noise Canceling Technology

Digital technology provides for optimal noise cancellation with outstanding audio performance. The NC100D reduces up to 98.2% ambient noise when the noise canceling circuit is activated.

Sony Sound

Full, natural sound is reproduced via full digital amplification in concert with a digital equalizer. The MDR-NC100D's large 13.5mm drivers work with digital sound enhancer circuitry to deliver wider frequency response and broad dynamic range.

How it Works

Sony NC100 Wave

The headphones have an inside microphone on each earpiece that captures the exterior sound waves and works in conjuction with internal circuitry to create an opposite sound wave. Ambient sound is reduced internal by synthesizing with a sound in the opposite phase produced by the noise canceling circuit.

Intelligent Auto-Selection

Sony Intelligent Auto Selection

Noise canceling that is optimized for your environment because not all ambient noise is the same. When you press the Artificial Intelligence (AI) button the headphones will automatically select the optimal noise canceling mode (for aircraft, train or office) based on intelligent analysis of environmental ambient noise. 

Passive Listening

Allows audio listening even when the power is turned off. Listening in an already quiet environment? Save the battery for later. Or should your battery run out mid-flight and you not have a spare, you’ll still be able to listen without the noise canceling activated.

Convenient Operation

Sony NC200D Side Shot

Easy-to-reach volume and built-in monitor function on the controller allows you to hear surrounding sound without taking off the headphones for flight announcements or conversation.


Vertical in-ear style housing and proper fitting earbud sizes allow the large 13.5mm drivers to rest comfortably in your ear.

Long Battery Life

Sony Battery

Compact and highly portable, these headphones are ready when you are. One AAA battery can provide up to 22 hours of noise-free listening enjoyment.

Travel Ready

Travel pouch, in-flight adapter, neck-chain style cord with controller (4.9ft), cord adjuster, and a AAA battery included.

Given the price range, this is probably as best you can get unless you are willing to pay more. The item comes ready to go with a AAA battery included. Aside from the On/Off switch to enable active noise canceling, there is a monitor button to temporarily disable all noise canceling and playing music and an AI button to automatically determine the level of digital noise canceling applied

-Generous cord length, comes with airplane mini stereo plug, different size earbuds to suit your ear
-Fits snug, fairly lightweight
-Audio passthrough when noise canceling is turned off (a major plus when you run out of battery)
-Corded headphones have the ability to amplify noise transmitted physically through the cord (e.g. rubbing against your shirt), these material of the cord minimizes this effect

-Audible hiss when in noisy conditions - this is common for active noise canceling technology, although a pleasant surprise this is not apparent in low noise environments
-22 hour battery life claim is significantly less than a Bose QC15's 35hr which I also own
-Physical interference noise (e.g. standing in front of an office fan, exhaust etc) is still an issue for in-ear headphones
-The AI button while works, I find having to press it far too often - it would be easier to automatically adjust the level of noise canceling based on the environment
-The monitor button brings all external sounds picked up by the microphone and plays it into the headphone, allowing you to hear surrounding sounds without removing the headphone. I find the resulting effect strange and much prefer just physically removing the earbud.

I had noise-canceling earbuds on my Wish List and actually ended up with a choice... "Keep the ones you like best." It took me a while to test them out. After I decided, I thought I'd share some notes. All comments are my personal opinions only!

- Sony MDR-NC100D; ~$100-160 on Amazon
- Panasonic RP-HC55; ~$45 at Costco

- Standing in front of kitchen range hood fan on high. I felt this is similar to airplane engine noise.

Noise canceling, no music:
- Mid-low range: Good for both Sony & Pana.
- Lowest range: Most remains for both Sony & Pana.
- Mid-high range hiss: Sony is lower.

Music: Natalie Merchant, Carnival
- Bass: Much better for Pana.
- Treble: Slightly better for Pana.

- Cord length: ~5' for both Sony & Pana.
- Cord design: Sony has shorter cord to L ear (bad if feeds are on R); Pana cords are same to L & R ears.
- Controls weight: Same for both Sony & Pana.
- Controls size: Sony is smaller than Pana and positioned a little lower on cord (i.e. more length between controls and ears).
- Volume control: Pana has volume control; Sony does not. Sony has 'monitor' function that pauses all music. Sony allows music to pass when unit is off (e.g. dead battery); Pana does not.
- NC settings: Sony has 3 settings and automatically chooses best; Pana has one setting.
- Earbuds: Pana rubber is softer and more comfortable than Sony.
- Battery life: Sony publishes 22h; Pana publishes 40h.

- Sony has better NC tech and sound pass-through when battery dies.
- Pana has better bass, comfort, battery life, and price.

My personal decision was for the Panasonic. I fly cross-country every other week and will use it mostly on long flights. I'll just carry an extra battery. It was hard justify Sony's ~3x higher price when I liked Panasonic's sound so much more.

Verified Purchase
I was torn between these and a more expensive over-the-ear model. I decided to go with the portability, since I would be using these primarily for travel. The sound quality is great (even with the unit turned off), the inserts are comfortable, and the noise cancelling worked as well as any over-the-ear model I have tried. The battery life worked as advertised; I got over 20 hours out of the first one. The only thing keeping this from getting 5 stars is the location of the battery and controls on the cord. You do need to clip it to your shirt or keep it on the tray table to prevent it from falling and yanking one of the headphones out of your ears. I wish they would have located the battery unit closer to the end of the cord near the plug so this wouldn't be an issue.

When I originally started looking for noise cancelling earphones, I looked to buy a pair of the Bose QC3's. Because of the reputation of Bose producing high quality products with great stereo sound, we know this comes at a premium price. Initially, I was willing to pay the $349 price until I had the opportunity to hear them. Bose has taken a few steps backwards in sound quality with the QC3 headset. The QC15's are still the best noise cancelling, premium sound headphones on the market....PERIOD.
That being said, and after doing some research, I decided to go with a set of noise cancelling ear buds. My goal was to reduce as much noise as possible while traveling on long flight over seas. So I figured I would try a set of NC ear buds. I already had a set of $50 Sony ear buds that were not NC ear buds, and a few years old. Although they were not noise cancelling, they reduced a lot of the noise and had great sound. So I decided to try the MDRNC 100D headset. The sound great, and 100 times better than the Bose QC3's. Even with the volume maxed out, there was little to no distortion, and the NC feature works great. The stereo sound was also superior to the set I already own. What is also nice is that they are noise reducing as soon as you place them in your ears. Couple that with the noise cancelling feature and great stereo sound, and you a great product. The only downside was the $150 price tag on Amazon and just about everywhere else I looked. I wasn't real crazy about pay that for ear buds, but IF had, they are worth it. The one great thing about Amazon is that they will offer the consumer other buying options from other merchants. I found these at for $99 and got them in two can't beat them at this price.
