Don't fly without it
This was my first set of noise-cancelling headphones, and I must say, the difference is astounding. Yes, the sound is good - yes, they're portable - yes, they have use-extending adapters, but the real difference is how you feel when you get off the plane.

I find myself much more relaxed, particularly after a long flight, when using these headphones. I've forgotten to bring them along on occasion, and the difference is significant.

I admit to using guinea pigs - I bought them as gifts to clients before buying one for myself. One client reported to me that he already owned a much more expensive set of Bose noise-reducing headphones, but preferred these Sennheisers.

I bought one for myself, and one for my wife. We love them, and leave them on every possible moment on the aircraft.

One tip - make sure you locate the "L" and "R" designations for the correct ear, as putting them on wrong can lead to sore ears.

Good, compact NC headphones
Very high performance noise canceling headphones without the bulk. Fairly comfortable to wear even while sleeping.

Great for airplane travel
A great, lightweight NC headset. I do a lot of traveling in all types of airplanes, and the 300s keep the noise out while providing excellent sound reproduction. In a jet airliner, the overall effect is terrific. In a turboprop, it is a godsend. The unique folding feature makes the included zipper pouch easy to store. I also like the airliner dual plug adapter, in case I want to watch what's on the airplane's entertainment system.

Wonderful headphones... except they broke after a month
I used these in a noisy cubicle environment and was very impressed at how it blocked out people's voices and ambient noise. They don't quite cover your entire ear but pretty close. The cords are nice and sturdy which was great (the Panasonic noise-canceling earbuds i got had very flimsy cords which caused a wiring malfunction).

BUT. After 1 month of daily use and being very ginger with my $220 purchase, I turned on the noise canceling one day and there was a loud, and eventually tortuous, static sound coming from one headphone. With the feature turned off it didn't happen. I returned them hoping for a replacement but I got a refund instead. I may try the similar PXC 250's which were very highly ranked by Consumer Reports. I'm keeping all the original packaging and invoice just in case!!!

Must-have for every traveler or office dweller!
This is my first purchase of noise canceling headphones, but the need was urgent as I sit next to a very loud colleague and in-ear headphones weren't cutting it. I find that with the item turned on, the music is a bit louder (though I like having the option of playing music with it) and the a/c or heat sound disappear (not that it ever bothered me) and all you can hear is your music. I still hear the loud cackling laughter occasionally, but overall, I'm able to hear my music without distraction. Even on the airplanes I don't hear the crying babies or people talking since the over-ear cups around to keep all the music in and all the noise out.

I was afraid of the pinching as I was always accustomed to wearing in-ear buds prior to this, but I don't find it painful at all, even after an 8-hour day.

The only negative, which I believe must happen with most noise-canceling devices, is that I occasionally feel pressure building in my head. I'm not sure why this is, but I'd read it before I purchased them, and even though I'm prone to severe migraines, I decided to risk it. I'm glad I did. The migraines have never been triggered, just occasionally and pressure in my head, but again, that's remedied by turning off the noise-canceling feature, and I still feel I hear the music better than with the ear buds.
