Question: Can you switch on noise canceling even  without listening to music?
Document: I owned an older version of these from 2005. These newer versions have a noise cancelling switch that is much smaller and less cumbersome, but I feel like they have lost a bit of the low end. They are just okay for listening to music, and I think for music there are certainly better options out there for the price. The noise cancellation is good, and they are, however, excellent for watching movies or listening to talk podcasts on a plane or subway.
Yeah noise cancellation is indeed moderate but still affective. Does do some damage to the hum of a jet engine for example. Biggest plus for me is the balanced tight audio though. Non hyped up low end with solid mids and highs. Slim and sturdy design, pretty comfortable. I actually like listening to music on these. The ability to use without battery is a plus too but this is just for utilitarian or emergency use since the sound is rendered dead. Recommended. Had these for well over a year.
I travel about 100,000 miles a year and these have been a godsend both for listening to music and surviving my plane flights without headache and stress.
Very handy.- Comfortable : The ear pad cushion is very comfortable and fits snugly.- Battery not a must : You can keep listening even if the battery dies. This is not an option in many active noise canceling headphones (read 'Bose').- Works well on my iphone with good volume.Overall, I give it 3 stars because it misses on the 2 reasons I initially bought them for - noise cancellation in office and sound quality.
The noise canceling works very well on transit and airplane noise, making listening to music while traveling that much more of a musical experience. I have used this model and its predecessor for a number of years, so I am used to the way they fit on the ears, but would suggest giving the headphones a serious try out to see how your ears feel about how firmly they press your head before committing.
I'm a bit of a headphone geek because I like music and I live in a noisy urban environment. The biggest advantage of these headphones is that they're so compact and lightweight. Sound quality is great considering the cost. Noise-canceling is OK, but not as good as with over-the-ear headphones like the Bose QC15 or Panasonic's RP-HC series. Because they're so portable, I primarily use these for walking around town or short bus rides while listening to an iPod.
It didn't cancel any noise. When I flipped the switch I couldn't tell any difference. It doesn't even cover one's ears, so how could it possibly work?
Even the wires seem to be of very high quality, as even when I'd accidentally pull hard on a wire that got caught on something, I never ripped it or damaged any connection points.Unfortunately, every pair I've previously had (including PXC-250 II) sooner or later developed the same problem- the switch that's turns noise cancellation on/off would start working intermittently and then stop working altogether. In some cases, there would also be a "scratchy" sound when the switch is flipped.
But the noise cancellation is sufficient enough to drown out airplane engines and NYC subway noises while listening to your tunes.In fact, I've auditioned about a dozen noise-cancelling headsets in the $200-300 range at an electronics shop, most of which were also bigger and bulkier, including Dr. Dre/Monster Studio Beats and none came close in accuracy and quality of sound reproduction to Sennheiser PXC-250.And even know I own other regular (i.e.
These are fantastic. If you put them on with no music at work or in a commercial jet, you will really see what the noise cancelling circuit does, cuts out a specific frequency of lowish hum/noise. I get the sensation that I stepped out of a public building/bus and into the middle of nowhere. I used these on a couple flights and they really do block out the noise and allow you to just hear music or whatever you might be listening to via your mobile electronic device.
Answer: Yes, and it's very useful to do so.  Conversely, you can listen to music without a battery in the headphones (but you'll need to switch the device to "off").
