Bose noise canceling headphones

Ah!
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.

There are times when I have trouble with noises in the house, and I
would love it if the head-phones could totally cancel all that out.
But.... not sure how far advertised is from reality :)

Re: Bose noise canceling headphones

They work great with constant type noise sources such as engines, fans, AC
etc. You can still hear people talking in the background, books drop.

I have a pair and love them!

Re: Bose noise canceling headphones

In reply to this post by dw-4

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 it.

However, in a domestic situation I find that although they do reduce
extraneous noise, they don't do a wonderful job of it and the background
hiss caused by the amplifier I find unsettling. Such hiss would not have
been audible in a noisy environment such as a jet. Now it might be that the
Bose are very very much better, but it might be worth trying to find out
before lashing out $$$'s!

Hope that helps

Re: Bose noise canceling headphones

In reply to this post by dw-4

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 AAA battery.

They work best on constant droning noises...perfect for eliminating generator noise during Field Day! They also work well on noise from things like fans and air conditioners.

These particular phones sit on your ears rather than surrounding them, so there's always a little noise that leaks in. I'm sure any model that completely covers the ear would be more effective. For the money I'm very happy with mine...wouldn't be without them!

Re: Bose noise canceling headphones

In reply to this post by dw-4

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,
ship them back for a refund.

I use a pair of $100 Sony over the ear headphones with my K3. They're
not noise cancelling but they do reduce the background noise enough to
be worth having.

Re: Bose noise canceling headphones

In reply to this post by Ken Alexander-2

Ken, thanks for including the battery information.
I have been attracted to the idea of noise-cancelling headphones for years,
but never had enough information about the power sources.
My interest has never been urgent enough to write or telephone the
manufacturers.
Curiously, mose advertisements don't mention that aspect at all. When I had
a job, I wanted a pair that could be powered through a wall wart.
In the rare occasions that I am on an airplane I would want to use
disposable batteries. The worst possible situation in my opinion would be to
have to use rechargeables. For daily use they create extra work, and for
occasional use they are never ready when needed.

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
they claim). They are not the most comfortable to wear for long
periods, but they are very effective.

I use and have used my Bose (QC-1 and QC-2) for years on rechargeable
AAA batteries. (The QC-3 comes with an internal rechargeable
battery.) Work great and most of the time can get an entire contest
in on one battery/charge. I keep some spares with me. I can always
buy a primary cell if I am caught somewhere without a charged
battery, which hasn't happened yet in years of use. Using AC mains
is the worst. It could introduce ground loops, hum, tether you to a
power source, extra wire tangle, etc.

Re: Bose noise canceling headphones

In reply to this post by K7TV

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 figure above from a 3rd party evaluation of the original Bose QC.

I've used the Etymotic ER-6 which is an in-ear solution with claimed average noise reduction of 34-36 dB for ~$85 at amazon.com.

http://www.etymotic.com/ephp/er6.aspx

The only problem with the ER-6 is it may be uncomfortable for some people. I've worn them in contests and had no problems for extended periods (i.e. 14-15 hours per sitting).

My personal favorite now is the Extreme Isolation EX-29. These are over-the-ear headphones that have 29 dB average rejection and can be found for ~$90.

http://www.extremeheadphones.com/ex-29.html

I had Prof. Amar Bose for my introductory circuit theory class in 1963. He was a great teacher, but IMHO there are much better noise-reduction solutions available for much less money.

73, Bill

P.S. I also once borrowed a David Clark aviation headset from a pilot friend. They were worse than awful...uncomfortable, did not block sound well and sounded distorted.

Re: Bose noise canceling headphones

I have seen rfi issues with the QC2 and the Heil noise cancelling headsets.
A couple of turns through a snap on fixed that. Neither are great at random
shack noises but both seemed to work very well on fixed sounds like fans. I
don't doubt that there are better solutions out there. Bose has one heck of
a marketing budget!

The folks at Heil told me that they will have some new headphones/sets at
Dayton this year that are supposed to be better then the Bose and more rfi
proof then their previous headsets and more comfortable.

OT Bose noise canceling headphones

I too use the EX29 phones and find them to be very comfortable and believe
me, you won't ever have to worry about hearing the amplifier fan. In fact,
the phone, someone knocking at the door, the furnace going on etc.

I use the Heil quiet phones plus headset and have never had any RFI issues running

the "loud" side but when I put these quiet phones on you hardly notice it's there.

Agreed on all counts. I work in pro audio, and have long used the more
expensive Etymotic ER4 in-ear phones to mix live music. Their noise isolation
is EXCELLENT if the earpiece matches your outer ear well, less satisfactory
if it does not. That's very much a matter of every person's ears. These
earphones, and competing models sold by Shure, are made primarily for
musicians working on stage. I own two pairs of ER4s and three pairs of Shures
(three different models). The ER4s and the higher priced Shures are all quite
comfortable, and easy to wear for the duration of a contest as anything else
I've tried. With all of these higher quality in-ear earphones, you can go to
an audiologist and have ear molds made to fit your own ears. That's pretty
much the ultimate both in comfort and in noise isolation.

I also like and use Sony MDR7506 headphones. They are comfortable and sound
great, but have far less isolation.

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).

K3LR loves the Bose headphones, and uses them extensively in his
contesting super-station. I've driven past Tim's station (it's on
the frontage road to one of the interstates at the OH/PA border),
but I haven't toured it. Some of his antennas ARE pretty close to
his shack.

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

Hi,
The Bose noise cancelling phones work GREAT for repetitive noise like
fan noise, rain on the roof (right W0YK?) and other things like that. I
have the QC2 having recently upgraded from the QC1s. They are the around
the ear model and the muffs have great noise reduction themselves.

Ah!
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.

There are times when I have trouble with noises in the house, and I
would love it if the head-phones could totally cancel all that out.
But.... not sure how far advertised is from reality :)

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 $$$

Re: Bose noise canceling headphones

It may be about time to end this OT thread. But, I will say that I used to
travel a lot for work, and I chose the Sennheiser noise canceling headphones
to make flying less tiring. I think that they sound better than the Bose
(with all of its marketing hype). They also cost less than half as much.
The battery pack is in a dongle with long life using alkaline batteries. I
enjoy having them available. I am biased toward wide frequency response
headphones (noise canceling in the shack is less an issue), and I use my
Grado hi-fi phones (SR-60) on the K3. My Heil Goldline mic is on a boom in
front of my face.

73,

Phil, NS7P
