I'm not an expert in this department or in any department for that matter but I'd have to say that definitely outweighs the stock earbuds.... But who knows maybe dftk could enlighten us.

Those things have their own battery so they will not draw from the ZVM. If anything, the ZVM batt will last longer since you may need less volume if the cancellation does what it is supposed to!

BTW, any audiophiles that come around here (I am not one) are going to tell you that BOSE sucks.

exactly. i have noise "isolation" on mine; i find myself listening to music at 2/3 or even half the volume i did before... imagine active noise cancellation!

I'm not gonna comment on Bose products per se...

What's that weird impedance rating? "350 Ohms low sensitivity, 1600 Ohms high sensitivity"? If that's anything like any normal headphone manufacturer states the impedance of their phones then these cans won't work without a really strong amplifier. Nothing over 100 Ohms impedance sounds good on a weak MP3 player's amp. ... but I guess these are just "Bose specs" and mean nothing.

Maybe they mean the impedance after the built-in amp and not what's delivered at the headphone-plug... which would be completely useless to know.

I'd suggest getting a decent pair of IEMs instead: they isolate much better than these "active" cans, don't need batteries, sound better and have better price/value ratio in general.

oh it means "low sensitivity and high sensitivity", because theres a switch in the headset that allows you to switch for "low sensitivity" or "high sensitivity"

Ah, they have a high/low switch... still, the impedance seems incredibly high. I can't imagine how they would work with a weak portable player.

i always figured that Bose was a good brand.. i wouldn't have expected Scientific American to have advertised a brand if they weren't a good brand..

Like anyone else, Scientific American will advertise for whomever ponies up the money, unless (like anyone else) they believe that the ads are slanderous, libelous, or politically incorrect to the extent that the dropoff in paying readers will outweigh the ad income. Please don't confuse advertising with endorsement.

On the other hand, if you were being sarcastic, my apologies. I've been warned many times that irony doesn't travel well on the web.

The only thing I will say about Bose, whatever the product, there is something far better for less money. That includes everything they make.

As stated above, Apple, Bose and Harley-Davidson. Good marketing, lots of hype and you can sell lots of an inferior product for more money. It just requires establishing your product as an icon.

Steve Jobs is a master at it.

EDIT: I just read that you already have the Quietcomforts... why not simply try them on the ZV:M and see how they sound? It won't drain the battery anymore than other full-sized phones, I assume...


Well, most of all it's a waste of money. With Bose you pay triple the price their stuff is actually worth... you could get Sennheiser PXC300 or even PXC350 for less money - and they sound better. They're also active noise canceling phones, a concept you seem to like. Believe me, everything is better in these Sennheisers than in the Bose's.

The Bose headphones should not consume any more amp power from the Zen than any other full size phones. As far as the battery in them, that is purely for the noise canceling system. Take it out and they'll still sound as bad ....... errrr... good as ever. If you have them and you like them USE THEM. And forget about what any of us say. After all, sound, no matter what any one says, is subjective. One person's junk is another person's treasure.

While you can get far better for less money, and my $60 Phillips HN110 sound at least as good as the Bose and I have compared them side by side, if they are already there, use them. And noise canceling is fabulous on an airplane.
