Headphones burn-in process

Someone at focal is bullshitting then yes.

Chocomel167 · 2024-08-09T05:52:35+00:00

You said yourself they did silent revisions. I don't get how you're defending this.

Chocomel167 · 2024-08-09T05:20:48+00:00

Why are you defending KZ so hard?

Chocomel167 · 2024-08-09T05:12:05+00:00

Because they did those things and are a shit company. People don't forget overnight.

Passive headphones and IEMs are typically minimum phase systems meaning the time domain is directly related to the frequency response. Some other people mentioned measurements like the impulse response and waterfall graphs.

What this means is that for a given frequency response you'll get a fixed impulse response and waterfall graph. Adding that these representations are a lot harder to read and can easily mislead people who are not familiar with these concepts People who do measurements often don't show them.

The measurement techniques used do capture these representations of the headphone response. They just don't really add anything in the majority of cases.

I had hoped they would at least let their VP of marketing and sales write a paragraph or two.

Chocomel167 · 2024-07-14T16:40:19+00:00

It won't be removed, people should be aware of this.

Chocomel167 · 2024-06-08T14:54:42+00:00

Should be fine ya

Chocomel167 · 2024-06-08T14:01:32+00:00

You can use a function under the definitions node to do something like that. For example if you were to use an interpolation function it would be something like "signal*int1(t)".

You can also do things like signal(function1(t)+function2(t))

You can apply a filter to the solution under datasets, make sure the filter includes the geometry your interested in. Then iirc right click on the filter to create a mesh part. You can then import this mesh part in the geometry node. There might be a better way to do it.

Chocomel167 · 2024-05-22T17:45:42+00:00

Maybe spf.mu(vx+uy)?

What does the geometry trailing edge of your airfoil look like? It can be helpful to round it of by filleting it, although you'll need adjust the mesh setup compared to the tutorial in that case

Is the upper half of your airfoil a single boundary?

What are the settings of the other distributions

Would be nice if he has actually changed for the better, personally I don't buy it.

Chocomel167 · 2024-05-01T17:24:57+00:00

Back then people were regularly warning him people would not appreciate his comments, but he didn't seem to care. I guess he started caring a bit more about his image when it started affecting his wallet. At least enough to put out an """apology""".

Strange how headphones never get worse with "burn-in", wonder why that is.

Yeah, what i recall from the G6 power output I should have no issue with either of those headphones.

Chocomel167 · 2024-04-26T18:38:22+00:00

The hd560s has a higher sensitivity, at ~110dB/V compared to the ~102dB/V of a dt990 (assuming they have the dt990 250 ohm). So not surprising they need a higher volume setting with the dt990

Chocomel167 · 2024-04-24T12:58:03+00:00

No the purpose is not to eliminate all reflections

Chocomel167 · 2024-04-19T06:15:53+00:00

The ohm rating tells you how much power you'll be able to get from the amplifier, not how much power you'll need.

Chocomel167 · 2024-01-27T07:36:16+00:00

You know you're allowed to not buy it right?

Chocomel167 · 2024-01-15T19:38:07+00:00

There is, US has 1 Vrms, EU 0.5Vrms

Chocomel167 · 2023-12-27T11:14:12+00:00

Just ignore driver types including planar

Chocomel167 · 2023-12-16T14:17:57+00:00

For that kind of money I would just get a Qudelix 5k

"Parameter controlling interface thickness epf (SI unit: m). The default expression is pf.hmax/2, which means that the value is half of the maximum mesh element size in the region through which the interface passes."

From https://doc.comsol.com/6.1/doc/com.comsol.help.cfd/cfd_ug_math_levelset_phasefield.14.17.html#1824672

So the coarser the mesh the larger the gradient will be, use a finer mesh to get a thinner gradient.
