Manufacturer's Description
The PXC 350 is a circumaural high-end travel headphone set with NoiseGard Advance technology for active attenuation of ambient noise

The PXC 350 enables an unprecedented sound experience for people on the move, 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

NoiseGard 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

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, i.e. without NoiseGard and without batteries

The PXC 350 is foldable and is supplied complete with a practical transport case, 2 AAA batteries and audio adaptors (double mono and 6.3mm)

Volume control integrated in the single-sided cable, which is detachable and replaceable, ensure maximum convenience for the user.

PXC 350 versus PXC 250
Having been delighted with the performance of the smaller PXC250s I bought a pair of PXC350s so that my wife and I each have something to use on flights and coach journeys. For the last few days I've been able to compare and contrast the two sets AND pester my wife for her opinions.

Sound Quality; I can't honestly say that the more expensive model sounds better ... they both sound excellent. However, the PXC350s enclose the ears and so the music comes from a 'place' that is a little off or away from the ear, rather than 'on' the ear and I prefer that. The slight 'hiss' that can be heard when the noise canceling is switched on is far less noticeable on the 350s perhaps because of this. Sennheiser have also reduced the hiss by comparison with the 250s. Either way, these are the two best headphone sets I've ever owned.

Noise Canceling; on a flight the PXC250s are excellent ... have yet to test the 350s. However, I HAVE compared them here in the home with loud music playing on my hi-fi and sat in the car. Basically, the noise canceling on both sets virtually eliminates the bass sounds from the hi-fi sub-woofer ... only the singing and higher pitches can be heard. It's amazing switching them on and off to hear the difference. In the car (wife driving!) the low engine and road rumble is also vastly reduced. As should be expected, the 350s DO cut out a little more 'noise' than the 250s, but not 3 times as much as might be expected by the price difference.

In use; the 250s are often criticized for having the separate electronic unit housing the batteries. Sure, you DO have to deal with it but when sat on a coach or whatever, it's no real problem. The 350s do not have this separate unit and so are much easier to use. I also prefer the single lead from the left earcup rather than one to each ear as in the 250s. Both sets are very comfortable to wear, though I do get warm ears and face when wearing the 350s for any length of time ... the 250s fare better in this respect.

Folding; obviously, the 250s fold into a smaller package ( the case is about half the size of the 350s case ). However, when folded flat the 350s are not much bigger than a Penguin paperback book, and they're extremely lightweight.

Conclusions; Here in the house, on planes and coaches, the 350s will be my preferred choice. However, in situations where I'll feel a little more self conscious the 250s will be used ( walking around town etc). Both are fantastic really ... especially when compared to the Bose prices!

And finally; I've read that some users feel a little pressure discomfort in the ear drum when using the noise-canceling feature. I don't notice it, my wife does. Time will tell whether she gets used to it or tries something different.

And finally finally ... regardless of which I'm using, I'm enjoying my music more than ever before ... and am able to listen with excellent quality wherever I am.

And finally finally finally ... both pairs really show up the differences in playback quality of different mp3 players. I played the same tracks on a variety of Apple iPods, Creative, Sony PSP and iRiver players. iRiver is the clear winner every time ... streets ahead of the others. Something to bear in mind if you're shelling out for good phones!

Hope you find my comments helpful ... happy listening

sennheiser pxc350 Vs pxc450
I as usual ummmed and arrrhhed over which set to buy the pxc450s at £169 (sorry Amazon not from you on this occasion) or the pxc350s at £107 from Amazon (excellently priced). I opted for the pxc350 as my impression was that the overall quality between the two would be the same in terms of headphone coils and sound with the only difference being the circuitry of the noiseguard.

Ok so first test i was in my office and they are a noisy bunch always shouting down the phone AND CREATING GENERAL DISTURBANCE. I work below an aircon unit too so i put this on and put the cans on. I used my sony minidisc as I wanted a decent signal without too much compression to test the range. With noiseguard off the sound is unimpressive and of course noise gets in, however with noiseguard switched on the aircon sound went and i couldnt hear the office noise just the pure music which sounded fantastic in fact i found myself missing the noise of the colleagues and found myself taking them off so as not to miss to much office banter. The next test was on the train home where i used my archos to listen to war of the worlds again the noise of the train disappeared. Next a film on the train now this is a different kettle of fish as the sounds are all shifted at one end of the spectrum with voices however Arthur and the invisibles did not disappoint the headphones allowed me to enjoy the film excluding the train noise, excluding the women a seat across me on her mobile and all the kids swearing. This morning I caught the train and listened to war of the worlds now i couldnt hear the train and sometimes opened my eyes as i wasnt sure if we were moving or not then i fell asleep and woke with my mobile vibrating. The point here is that the headphones worked fantastically and it was as if i wasnt on the train I mean you can feel the movement but not all the noise. I have no doubt that on a flight will be the same all the external noise will go. These phones are true to their claim that they get rid of most of the noise 85% I mean to me it seemd all or most of the external noise went so I dont see much gain in buying the more expensive pxc450s however I have not tried those the only perceivable difference is that the 450s have the voice pass through facility so you can talk without removing the headphones but lets face it its polite to remove them if someone is speaking to you.
Pound for pound the 350s are excellent and will offer better value for money and if you think what else is available at £107 then these are miles in front of the competition. purely impressive technology contained in a well robust and "sexy" looking headset. Ok you have to get used to the sets being over your ears and they feel warmer but you get a superb sound true to the original and if the batteries run out ok you will be disappointed at the sound but I bet you run off and get a spare set of batteries. The case is well made and the phones fold flat for storage. you have space for batteries in the case and the aircraft adaptor and 6.5mm adaptor too. Dont hesitate buy them I cannot recommend them enough as Sennheiser have put everything into these.

Brilliant
I have had these since christmas 08 and i havent been dissapointed.
It is packaged very well, and comes with the following accessories:
Travel case(very useful!)
6.3mm adaptop for use with hifi equipment
aeroplane adaptor for use on aeroplanes

The sound quality these produce is fantastic. Im no audiophile but i appreciate the sound of good music. It has a good range, the bass is good without being overpowering, and the sound is generally very open.

I have used them mainly for travel on the London Underground with my 60gb iPod. the noise cancellation is excellent, with the all to familiar raquet made by the trains, reduced to almost nothing when music is playing with the noise cancellation on. One thing to point out is that the cable is fairly long, although not excessively long which could be a problem to some people(not me)

I cannot comment on whether or not it is worth upgrading to the 450's as i have not heard them but im sure you wont be disapointed with these! Another quality Sennheiser Product!
