The Sennheiser PXC 350 noise compensation headphones reduce outside sounds such as engine roar and background conversation so you can enjoy your music at lower and safer volume levels while traveling. And they deliver warm, detailed sound, thanks to Sennheiser's patented speaker drivers and careful design.

A built-in switch activates the noise compensation. Tiny microphones in the headphones pick up the sounds of your environment. Advanced circuitry then creates a signal that "cancels out" much of this external noise without affecting your music or movie soundtrack.

The PXC 350s feature generous padding on the earcups and headband so you can wear them comfortably for hours on end — handy for long trips. And they fold flat for compact storage in the provided travel case.

Product Highlights:

  • compact, folding, around-the-ear design
  • padded, closed earcups and adjustable headband
  • up to 18 dB attenuation of ambient noise
  • frequency response 8-28,000 Hz
  • detachable 5-foot cord with stereo mini plug
  • full-size headphone and twin-plug airline system adapters
  • travel case
  • requires two "AAA" batteries (included)
  • weight 8.64 oz. (not including cable and batteries)
  • warranty: 2 years
  • Our 60-day money-back guarantee

They're great!

Written By Dan, SF Bay Area on Saturday, July 24, 2010

I've had these headphones for about a week and really enjoy tnem. I prefer headphones over earbuds and these are incredible. Often I don't even need the noise canceling turned on. But when traveling through a very noisy subway tunnel it was nice to turn that on and continue my listening. They are bulky, but they feel like they are very well made and should hold up very well. These wouldn't do well for listening while running or doing other active sports but for superb listening they are great.

Incredible headphones! Today is my first day using these, and I'm impressed.
They produce a great sound-stage and even work great without running on the
batteries. I was a little disappointed with still being able to hear a lot
without music being played, but ultimately, I will use these with sound being
played so I didn't feel this would take a star off for me. A little expensive
but well worth it, and it even comes with it's own travel case! :)

Awesome headphones!!!!

Crutchfield Customer Review (What's this?)

I bought these headphones about a year ago from Crutchfield and they still sound fantastic. The quality of materials and the great sound from the PXC-350 make it hard to pass on these. I tried the Bose and they sounded good but these are more comfortable, sound better, storage case is smaller and the price is less. It was a no brainer for me...

Hey this is Brad'
I rolled the dice on this product. To find out all they make is headphones. They are made for air line pilots. The first time I heard them I was shocked. rock @ roll, country and christian music sounded so different. Clear mid highs with the bass not muttering them. The bass is tight and smooth. The range on the frequences, blended together crisp. I am glad I bought this, it was worth the money. I play bass and this allows me to hear it clearly.

AWESOME product. I listen to drums & base, Jungle and techno which all require VERY strong base support.

6" cord is a lilttle short.

I bought these headphones for my son to use with his computer and mp3
player. I went with these over Bose because of the discounted price and
more sturdy build quality - he is 17 and I was concerned the Bose would
not stand up over time. He is extremely pleased with them. Great sound
and noise reduction, very comfortable, and solid build. I would definitely
buy them again.

Product Research


Overview: The Sennheiser PXC 350 are closed, dynamic, over-the-ear stereo headphones with active noise compensation technology know as NoiseGard Advance, designed for use with any entertainment system, including in-flight audio systems. Passive and active noise reduction enable you to enjoy music even in noisy environments.

NoiseGard Advance Noise-cancellation Technology: NoiseGard Technology is an active noise compensation system which Sennheiser originally developed for use by pilots, who have to rely on good sound quality and efficient protection against ambient noise even in high-noise environments. NoiseGard actively compensates the noise, based on the physics principle of sound and counter-sound. The PXC 350 features the NoiseGard Advance technology. This technology is a further development of the filter functions used in the original NoiseGard system, and enables even better active attenuation of ambient noise of up to 85%. It is of course also possible to use these headphones passively, without NoiseGard and without batteries.

Diaphragms: The PXC 350 enables audiophile sound experience, thanks to its adaptive baffle damping in combination with the patented Duofol diaphragms, which prevent unwanted partial oscillation and thus guarantee a highly natural, lifelike sound quality.

Volume Control: The headphone's volume can be adjusted directly on the headphones from the in-line remote integrated into the supplied headphone cable.

Comfortable Fit: The PXC 350 provides a comfortable fit and high level of passive ambient noise attenuation thanks to its over-the-earcup design and padded adjustable headband made of top quality materials.

Removable Headphone Cable: The headphone cable of the PXC 350 can easily be removed and replaced for long service life. You can also remove the headphone cable to use the headphones as a passive hearing protector device.

Airline Stereo Audio Adapter: The supplied airline stereo audio adapter allows connection to a variety of aircraft entertainment systems.

Travel Case: The headphones fold together for compact storage in the provided case, making them an ideal travel accessory.
