Sorry, I must have goofed on the submission, not even known it, and resubmitted. The ATs look interesting...

1) do the PXC450 work with NiMh batteries as well as with alkalines?
2) do you hear a clicking noise some people reported (maybe they had faulty pxc450?) when the battery is in, there is no music and the noise cancelling is ON or OFF?
3) how do the headphones work with a portable CD/MP3 player? (the specs show that engaging the noise cancelling rises the impedance up to 750 ohm which is rather high and may be difficult to drive from a portable source; on the other hand if the PXC450 uses internal amp, it may somehow compensate for the lower levels from a portable)

Recently I have been wondering about active noise cancelling headphones for the office use (AC noise, computer noise, people talking, etc.) and PXC450 have been receiving a lot of attention from the press...

Thanks!

1) It comes with 2 batteries, but need 1 ony at a time. I think it should work with either type of battery.
2) I dont understand your question. Whenever you want to change battery and/or switching NC on/off, you need to take it off your head. Is that your question?
3) It sounds reasonably good with my Zan vision:M. A dedicated amp makes it sound somewhat better.Senn centainly knows when/where users are going to use it mostly. Dont worry about it.
4) The sound quality is niceably downgraded when NC=on. But that is expected.
5) Comparing pxc450, HD650 sounds more refined and yet veiled, and deeper in bass so it makes you feel wam. pxc450 must be more articulate, otherwise would have sounded too subtle when NC=on. But HD650 is not NC-capable and requires a dedicated amp.
6) if you have Grado 325, then pxc450 is more like it then hd650 when nc=off. But of course, they sound differnt here and there.
7) I found something very inetresting about pxc450. It is a closed phone, unlike pxc300. If I move my head around, especailly left or right, so that some air might leak out of the phone, then the sound quality significantly impacted. I am used to open phone so that is a little problem. But as long as it is closed, then bass and sound stage are quite impressive coming out pxc450, when nc=off in particular.

I was thinking exactly about iPod when I asked my questions. Thanks a lot for the answer!

Aactually, I was thinking of using NiMh (or NiCd) rechargable battery instead of regular alkaline. The difference is that alkalines are rated 1.5V while rechargables are 1.2V.

I read info on ATH-ANC7 that it needed alkalines and wouldn't work with rechargable batteries (is that true?). And I was wondering if this was the case also with PXC450...

I was refering to some strange phenomenon noticed by few people. They heard quiet clicking when the baterry was inserted in the PXC450 but the noise cancellation was off. Right now it is still unclear to me why some people noticed this while others had no such problem.

Thanks for your other thoughts about the PCX450. Especially the comparison between the PXC450 and HD650. I realized that NC would degrade the sound to some degree but, from what you wrote, I think they must sound quite decent.

Thanks again!
Peter

Any more notes on your use of the PXC 450's?

Wrong quote, sorry. Any more notes/thoughts on your use of the PXC 450s?

I have only used it when I traveled. At home, I prefer my Mackie HR624MK2 plus E-MU PS12 sub. So it has been packed in its case since I came back from my last fright. I am going to use it at work. Then I give you update.
