I use these headphones, the QC2. I paid around $100 for them on ebay
over a year ago. There's an occasional hum in the right chanel I get
every so often but was just sent a fix for it a couple days ago. As
the humm is not there I haven't done the fix. (the hypothesis is a
potentiometer needs
I tried a pair in a bose store and was unimpressed, cant turn the gain
up enough, so I built my own, they are a safety hazard now :)

I use these as they contain no electronics, just good isolation.
They're not cheap but they work great.

Yup. :-) Time to end this thread.
In general, once an OT thread has generated over 10-15 messages, I'd
like to ask that people self moderate. We really need to limit volume to
avoid email list overload.

I've always wondered how well Bose noise cancelling phones worked.
Do they really cancel noise external to the head-set

I understand the concept...mic the external noise and mix it back into
the earphones 180 out of phase.
Just never got a chance to see how effective.

I bought some noise cancelling Sennheisers in Changi Airport a couple of
years ago, they were not as expensive as the Bose, but not far off. They
did a fantastic job of cancelling the sorts of frequencies which are
troublesome in a jet; I found that I could turn my iPod right down and still
hear
be without them!

A lot of guys here at work have the Bose NC headphones to try to cancel
out nearby office noise. I suspect they work OK in that application and
no better.
Doesn't Bose have a liberal return policy? You could answer your own
question by ordering a pair and seeing if they work for you. If not,

I have a pair of Sony noise-canceling headphones that I'm really pleased
with. They were $89.95 at Best Buy. Model MDR-NC6. They run on a single

They work best on constant droning noises...perfect for eliminating

I've been using a pair of Direct Sound's Extreme Isolation headphones
for years. They are very good for blocking out noisy environments.
They are not noise canceling, but rather use passive techniques (tight
fit, sound absorbing material) to reduce ambient noise by 29dB (or so

If you **truly** want to block out ambient noise, there are much better and
less expensive solutions. If I recall correctly the $300 (fair traded) Bose
QC2 units only have ~10 dB of attenuation. Bose doe not spec their sound
reduction because it really isn't so great. I think I found the 10 dB

One other comment in this thread re: RFI. I've not seen the Bose
cans, but I operate fairly often at N6RO, where a lot of guys bring
Heil noise-cancelling headsets. They DO have RFI problems, and Ken's
antennas are mostly not very close to the shack (mostly 200 feet or
more).

They work - about as well as a K3 does - so go buy them now!

I don't know the 'street' price of the Bose headphones, but the
suggested retail puts them on a par with a David Clark H10-30 aviation
headset. Over 20dB of passive quieting and a comm quality microphone.
I've had a set of H10-40's (27dB) for 20 years. They are indestructible.

I have both the Bose and the Heil noise cancelling headsets, hands down the
Bose is better. I don't like the big dongle on the Heils, I just wish the
Bose had the boom mic on them I've had no RFI with the Bose but have had
with the Heil. The Bose is more comfortable but very $$$
