active noise cancellation?

Archived from groups: rec.audio.pro (More info?)

What are best (active) noise cancallation headphones for pro audio purpose?
I currently use Beyerdynamic DT250 for almost any app but would like to have
something _smaller_ and more _portable_ for overall use while on road.

Tried my bro's Brookstone Soundshield 250 headphones during last flight from
Chicago to Paris
and they worked very well. Also in my noisy VW van the sound isolation was
great making me to
want own pair as well.

But since dont know anything about Brookstone or Soundshield I would like to
see or
hear other options as well.

I know Sony and Sennheiser has something similar and Bose as well, but dont
know which
is best for what purpose and how they perform. How about "the boom quiet"?

Also since I use my DT250's for demanding purposes I dont really place extra
weight on sound quality
but surely they need to sound good as possible.

Does active noise cancellation still place the pressure to ear (making it
still harmfull)?

also if someone know good forum/site/review/... for active noise
cancellation stuff, please let me know.
Did not find anything specific manufacturing site for Brookstone
Soundshield's but I can say that for the
price (150usd) they perform pretty well. Sound quality was not tested since
had only feed from poor
airplane radio/tv supply.

thanks in advance,

Airplane, noisy open rear van etc. seems to work very well. I do get
pressure
in ear while active protection is on but not like I could hear it.

in-ear phones can be right if good one. only problem that most basic
in-ear's keep
falling from my ears. Dont know really how its with good S's (senn, sony,
shure)
or Koss.

I brought mine from Germany couple years ago and it has got some rust on it
after that.
cars are only vehicles (specially vans) so dont really care as long it runs.
Since its self imported
it does get rost but those imported to Finland as new are protected against
rust. You hit it or
skip washing/services/rust protection program (every 5 years or so) it
surely does gets in rust.

my van is not that historic (more like teen aged).... but yes we do have
salt on roads that gives nice brown colour to our cars.
cars from 70's or early 80's do have better poison paint and more metal so
they seems to be even better condition that newer ones.
also because taxes here in Finland, cars do get old age while in traffic.

Disagree, with regard to the bodywork at least. Recent vehicles from
most major manufacturers use galvanized body panels and are far, far
more likely to survive tough environmental conditions.

ok.. well need to get some isolating in-ears.
