You sound like a regular Head-Fier with this post, it's astonishing. There may be hope for you yet...

I had the E4c's for a time and wasn't blown away either, however- I did find them more enjoyable than the Etymotic ER-4's.

Well if one were to say that you can get good audio from an ipod and headphone under $200.....no one would refute that. I certainly believe in focusing on a budget. There's been no intellectual debate about how the audio quality of an expensive setup compares, though, so as such you cannot take the "article" or this thread seriously.

Also, I wonder how credible n2xe's ears are since he's just claimed that he hears more bass out of the SR325i vs the CX300. Technical data begs to differ:

but maybe that's his humor surfacing again

Frequency (f) of sinusoidal wave is the inverse of its period (T).
f=1/T.

And its angular velocity W=2pi(f) because there are 2pi rad in one period.

This is fundamental to any engineer and physicists.

Hmm... I guess that makes my empty piggy bank unassailable then. I feel so secure now!

Are you even remotely serious? Yea, a sine wave rotates between 0 and 360 degrees to complete one cycle.

thank you! finally some sanity...

What's the source for this data?

Headroom I believe (Online headphone store).

Do you see the huge headroom image in the background of the graph n2xe?

my god ur back?

i can't count the number of times we've told u the difference between the frequency of a sine wave is not angular velocity, and in a language kindergarteners can understand.

-frequency is a "number", angular velocity is a vector (an "arrow" of a certain length pointing in a direction)

-frequency is measured in hz, angular velocity is measured in rad/s and has a direction

they are not the same thing. there's a relationship between them, but they aren't the same thing. acknowledge at least this far and we may make some progress.

that's angular speed. velocity has a direction. if u skip the direction, u may run into problems.

actually, "sine waves" don't rotate.

imagine u are on a ferris wheel. think of how high ur off the ground and graph it against time. the graph will be a sine wave. but it's the ferris wheel that's doing the rotating, not the sine wave.

so the statement is incorrect. it is merely a nitpick, however, as are a lot of what we're saying.

but u don't need to begin with "Are you even remotely serious?", which is just rude, and reserved for those occasions when someone is completely wrong and ur completely right.

Not being an engineer or physicist, I enlist the aide of wikipedia:

http://en.wikipedia.org/wiki/Angular_frequency
http://en.wikipedia.org/wiki/Angular_velocity

Still waiting on that SR-80 graph n2xe. Since I can't find it, maybe you can.

 

[Jigglybootch]

I thought angular velocity was related to the rotation of a particle or body along a fixed axis? And as far as I know, the frequency of a sinusoid is not a vector quantity (which angular velocity is). I don't see how the two are the same.
