NoiseGard 2.0 and TalkThrough Technology

The switchable NoiseGard 2.0 technology reduces ambient noise up to 90%, with active/bypass mode for use as a noise cancelling or closed-back audiophile headphone. The innovative new TalkThrough function allows the user to communicate with neighbors without taking off the headphones. Unwanted background noise, such as the roar of the airplane engines, is filtered out so that only the neighbor’s voice is passed on through the headphones at top quality.

Original Review:

I compared these headphones side-by-side with five other noise cancelling headphones: Bose QC2 & 3, JVC NC250, Audio Technica ANC7, and Sennheiser PXC-250. I was in the market for a noise cancelling headphone because I travel a lot and I wanted to be able to watch movies or listen to music in relative isolation. With the ipod earbuds, you have to blast your ears in order to compete with the airplane's engines and I want to preserve my hearing. My main criteria were sound qualifty, noise cancelling, and comfort. All three were very important and I didn't really want to compromise on any of those categories. The only headphone that excelled at all three was the PXC-450. I disqualified all but the PXC-450 on the basis of out of the box testing.

The JVC was disqualified right away on the basis of its cheap build quality. It does not fit snugly on your head, it is very loose. The slightest movement of my head and the earphones would slide around on my ears. Because of that these headphones offered zero passive noise cancelling. Sound quality was okay but nothing special. These headphones never really merited serious consideration.

The Audio Techicas are one of the most popular headphones on Amazon. I read the reviews of this headphone extensively, and most people rave about these headphones. The only criticism of them I saw was sound leakage. People complained that when you listen to these headphones, people around you can hear what you're listening to. They were right.

I bought both the Bose QC-15's QuietComfort® 15 Acoustic Noise Cancelling® headphones and Sennheiser PXC-450's Sennheiser PXC 450 NoiseGard Active Noise-Canceling Headphones to compare them side by side before plunking down ~$300 for headsets.

The Sennheiser PXC-450 headset is built much better than the QC15's for durability AND comfort. The quality difference can be seen in the wire gauage, battery compartment hardware, adaptor finish quality, and ear cup cushion. Sound quality was also richer and seemed more encompassing/fuller. I'm no audiophile by any means, but that is my best subjective judgement.

The QC15's however had far superior noise cancellation. This my main determining factor between choosing which headset to keep. The noise cancellation isn't nearly as good as the demonstration unit found at retailers would lead you to believe. (those are likely configured to generate test noise at the precise frequencies of the noise cancellation circuitry of the headphones). My test was simple, I used a couple of air purifiers (not fans) running on high that reasonably simulate the white-noise like droning sound of being on airplane. Again the QC15's were much better than the Sennheiser PXC450's with respect to this non scientific test.

Bottom line, if noise cancellation is your top priority and your willing to sacrifice a little on build and sound quality, then buy the QC15's. Otherwise, if you can live a little bit more ambient noise intrusion and want greater sound and build quality, buy the Sennheiser PXC-450.

Hope I can help anyone out there.

Bose QC25 vs. Bose QC15 vs. Beats Studio (by Dre.) vs. Sennheiser PXC 450 vs. Audio-Technica ATH-ANC7b

Disclosure: I have tried all these on an airplane. I am not an audiophile. Noise Cancelation is the most important attribute to me.

The Carrying Case: All four are quite durable and stiff.
1.) Bose QC25- Very small, compact, and just big enough. Does not really have room for anything else. Could fit in a briefcase.
2.) Bose- QC15- This case is bigger than the QC25 (Which could be a good thing. Doesn't feel much bigger, and still has room for ipod, Gameboy, batteries, whatever).
3.) Sennheiser- Square shape, low profile, however not a lot of room for anything else in case.
4.) Audio Technica- Nice big case if you want to carry extra stuff (Nintendo DS, ipod, etc).
5.) Beat case is very elegant and hip, but very wide and skinny. Maybe room for an ipod and that's about it. Caribbeaner Clasp.

Build Quality:
1.) Sennheiser- you can tell this is built VERY well. Strong plastics, good components, thick cord. Top notch. You feel like you are getting something really high quality.
2.) Beats appears to be extremely well made. Heavy duty industrial plastics, metal fasteners. High end box, thick cord, great packaging, solid construction. Only concern of mine is that the battery compartment seems a little fragile.
3.) Bose25 is a step up here from the 15. Detachable cord. A little more substantial feeling. Touches of aluminum on the headphones, and some nicer quality padding. While not as substantial at the Sennheiser, they do feel more luxurious and a little more solidly built than the QC15.
4.) Audio Technica- Nice solid construction, appears durable. Mostly heavy duty plastic.
