General
The same ingeniously tiny but sealing design as the PX200. The earcup colour seems to be different on the PXC250, a dull Unterseeboot grey. I can't help but feel that it looks cheaper than the PX200. The noise cancelling component comes in a stick with a swivelling belt clip about the size of a really fat pen, and is permanently attached to the headphone via a 1m or so cable. The cable from the noise cancelling unit to a regular 3.5mm headphone plug is about 0.75m. There's space for 2 AAA batteries, and an on/off switch. Strangely, the fit on the PXC250 seems a lot better than my previous PX series unit, the PX200. Even with my prodigiously huge head, the PXC250 sits fine with headband 'clicks' to spare. Long-term (1 hour+) continuous wear is comfortable.

Sealing
With the Noisegard off, it's a lot like the PX200. Surprising amount of sealing for a tiny headphone like this, but not anywhere like the HD280 Pro for example, which is something of a benchmark in this respect. Hit the Noisegard switch however and... Ambient rumbles and clanks fade into the background. It's VERY impressive. It won't drown out baby noise for example, but low-frequency components that are an integral part of train, bus and aircraft travel will simply go away. For aircraft/train/bus use, you don't need to have a source plugged in, you can just use it as a pair of earmuffs.

Sound
Noiseguard has a major effect on the sound. WIth it switched off, the phone sounds like the PX200 (please reference PX200 reviews but in my view it sounds too bass-heavy like the HD212). To me, the PXC250 sounds better than the PX200 with Noiseguard off (albeit still bass-heavy) because it fits me better than the PX200 did, so I get some semblance of trebles now. The only difference seems to be that the PXC250 is noticeably quieter than the PX200, with or without Noiseguard. An ear-deafening volume setting on the Eggo D22 was reduced to a below optimal setting on the PXC250. I found myself setting the volume to Max on the Sony Minidisc to get a good sound, and about 25 out of 30 on the Sharp to get a good sound level.
Turning on Noisegard has the effect of taking away a lot of the bass response of the phones, markedly changing the character of the sound. The quality of sound with Noisegard on is definitely not that from a £90 ($140) closed phone. In fact soundwise it has more in common with the Y5,500 ($40) Sony Eggo MDR-D22SL. Bass can pack a kick, given the right music and some assistance from the portable, but on the whole it's weak. Trebles are fairly well represented, and mids are somewhat lacking although perfectly discernible. But on the whole, it's a perfectly listenable sound, more so I think if your portable has EQ of some description to tailor the response with. Even Bass Boost helps to round out the somewhat thin feeling sound with Noisegard enabled.

Conclusion
The way that it can provide a calm oasis in trains, aircraft (yet to be tried but I will do so soon), etc is a major advantage. I don't know if Etys would seal out more noise, but I would imagine the PXC250 to be a lot more convenient in general use. Not great sounding, definitely not 'hi-fi' but OK for most uses out of a portable. Theyre very portable (packs into a space far smaller than an MDR-7506), provide very good noise cancelling and fair sound.


Highly recommended for frequent travellers.

Yes... I think I've found my ideal compromise too. Soundwise not THAT hot but perfectly listenable. The cancelling works surprisingly well. Was a bit of a shame to let the HD25's go too, but they just weren't getting any use.

Just an update also. I'm really liking this noise cancelling. General noises areound you are attenuated by the design of the phone, and the noise cancelling works on the lower rumbling sounds (until a certain point... there's only so much a tiny headphone can do to counter very low frequency noises). The bass is not a disaster at all. Just a slight bit of bass enhancement from the portable, and I was very happy with the overall response.
It may sound like only a decent $40-$50 phone, but the major difference is that you can hear it all whatever the noise around you is. I LIKE it.

Further edited update. The change in the music between Noiseguard on and off is MAJOR. I don't think I stressed this enough. Stand astonished as flipping a switch removes that huge wooly bass of the PX200, to come up with actually quite an agreeable sound, combined with the advantage of noise cancelling. I think I misstated the lack of mids in the original post, I may have had the EQ on the wrong setting with the Sony (sheepish grin) I've listened to it far longer with the Sharp today which only has bass boost, and it's fairly well balanced. There's a definite added hiss and added artifacts in the sound which can be heard every now and again, but on the whole it really is worlds apart from the PX200's sound, which you can sample (and grimace at) with the Noisegard off.

Bangraman...

This pen thing you mention... is it like a microphone? - the noise cancelling circuitry? - does the 'cancelling' get worse when the 'pen' is in your pocket?

And... where did you get them from? Ask Electronics?

Thanks
 
Jan 9, 2003 at 9:15 PM Post #8 of 16
Yes, I got them from ask. And as for the 'pen' thing, that's the odd thing. I can put them anywhere, under a jacket, and they still cancel... So I have to assume that the PXC250 headphone itself has it, but when I accidentally bang the 'pen' against something there's a noticeable blup in the sound. I really don't know where the mic is. However of course the electronics are in the 'pen' as well as the battery compartment.

They last a remarkably long time. I haven't yet run out of batteries on the PXC250 in use. I just change them every now and again when I feel like it... Maybe every three weeks? Your mileage may vary, since these are ONLY my travelling headphones... I don't use them for anything else. When I do use them, Noisegard is always on and many times I forget to switch it off and only notice it a few hours later. It still works fine the day after, the day after that, etc despite this.

It's been touched on several times before on this forum. No problems with the Sharp MD unamped, I set the volume about 25 out of 30 and it's a sane listening level while commuting. With the Sony MD when I had it, I had to turn the volume all the way up and even then I was left slightly wanting, so you can see my 'slightly weak' comments in the review because I was trying it with the Sony MD.
So it's not ideal unamped with the lower powered portable gear, but it should work fine with things like hard disk players and of course Sharp MD's.

I received a pair of the PXC250s and used them for my first transcontinental flight last week. I found that the noise cancelling was OK, but I was disappointed in their sealing ability. I found that to get really good noise cancelling and fidelity, I needed to clamp them against my ears using my hands--not a practical way to use headphones.

I would rate them as better than non-noise cancelling headphones for airline use, but I switched back to my ety 4Ps for the flight home. I sent my Sennheiser PXC250 headphones back to J&R for a refund.

Oh God... Please don't say things like that. I've already got a CD3000 to buy, and now an Ety too? Nooooooo! Do you realise I could already buy a really nice secondhand BMW or Mercedes with what I've spent on headphones alone (not audio equipment) over the last couple of years?

Bangraman...

The ETYs sound like nothing you currently own... they'd more than likely be fatuiging in the long run... thats why I sold mine on...

Maximum fidelity maybe, but for me... minimum emotion...

Sorry ETY lovers, just my own personal $0.02
