They are all audibly transparent DACs. They all sound the same.

Want less piercing treble? Use either a peak filter for specific frequency, or a shelf for to pull the entire treble range down a couple dB.

interesting article, but for some reason it stops right before the point where I would EQ the cheap cans to bring back the frequencies they’re lacking. isn’t it the most obvious next step to do this and see if that makes them sound faster? and then the next question would be: do all headphones sound identical once the FR is equalized between them? my guess would be no, and the next question is what measurements or graphs would explain the remaining differences.

Can you explain what you mean by "time delays do not alter frequency domain". A delay in time domain causes a phase shift in frequency domain. So it does alter the Fourier transform.

Oh, ok. You clearly have no idea how headphones work.

All you need to see is the frequency response. Over damping and under damping might affect it, but why even bother looking at it, when the result i.e. changed FR can be measured directly?

I have two of the Woo Audio stands, they are a bit pricey but are of top notch quality.

I think you are just wrong, and you do not seem to know what flat frequency response looks like in impulse response graph. It is one sample long singular spike, followed by perfect silence afterwards, forever. You could say that studio monitor speaker systems strive to reproduce just such an impulse, and the closer it is to a very narrow spike, the better the acoustic system. Even this headset looks like it is not that far from perfect impulse apart from some ringing afterwards which suggests it has some resonance peaks and probably highpass filtering because the impulse goes below zero, and that would indicate it cancels some of the sound it produced earlier after a time delay, which is how highpass filters generally work. I don't know, it is really hard to try to read the frequency response off impulse response.

It is completely obvious to me that time delays do not have impact on the magnitude spectrum. They have an effect on the complex spectrum because phase (and group delay) are different and are encoded in the ratio of the imaginary and real parts of the complex number which is usually not shown because phase angle is difficult to relate to anything we actually hear. In that case, group delay would show the added fixed delay just fine, though.

I can only assure you that from mathematical point of view, the impulse response and complex frequency response can be converted to each other without loss. Whether Fourier analysis is good model of human hearing is perhaps a thornier question, as this isn't quite how our ears work, but I think it is still plenty useful as a construct.

Well, if damping is odd and affects sound you will see that in the frequency response graph. Therefore, just skip the damping measurement.

It does not. It is just like there are sound over 20k in the world but you never gonna hear them. Its like not seeing ultraviolet, and if a screen has capability to show ultraviolet it won't matter at all to us.

Hello, here's what I do with my TWS earbuds and TWS adapters (like FiiO UTWS3/5) or really Bluetooth/wireless/rechargable/etc. stuff in general: I try to only charge it when it has no battery or will have no battery soon.

So if I am going to eat, I just either turn off the TWS earbuds/etc. or like leave it playing. Do not eat with TWS earbuds or IEMs inside your ear btw, it's not good for your health/comfort.

And yes if your TWS earbuds or Bluetooth devices have app support sometimes there'll be settings to set it to 80% battery life or something like that to prolong the battery. This will help preserve the long term battery life in theory.

So for now just keep playing if you want to maybe save the battery life in the future. But most people will not mind the disposable nature of TWS earbuds or Bluetooth stuff and so they'll be surprised when it has way less battery life within 1-2 years.

Realistically, people are always doing that recharging habit though. It's actually very rare that people are like me where I will use the TWS earbuds/etc. without ever taking them off.

Most TWS earbuds/TWS adapters/etc. last only say 5-6 hours in practice despite claims of 8 hours or so. This depends on if you're using regular AptX, LDAC, etc. And like how loud you listen too.

Always make sure you have that perfect vacuum seal in order to save your hearing health and also to get more batter life out of the TWS earbuds.

You have to specifically look for TWS earbuds/Bluetooth devices that have long battery life if you want legit 8 hours or so.

Try Spinfit W1, FiiO HS18, AZLA SednaEarfit XELASTEC, Dunu S&S, etc. ear tips for possibly better fit/seal, noise reduction/isolation, and comfort.

You can use ear tips for wired IEMs with TWS earbuds (and vice versa) but they'll probably be too long/wide for the TWS earbuds case and so it won't charge at all, you'll need to remove the ear tips each time.

Try Spinfit CP360/CP1025, AZLA SednaEafit MAX for TWS, etc. Those are specifically made for TWS earbuds, they usually have adapters for weird nozzles like Apple, etc. devices.

There's also Final Audio E for TWS ear tips. The smaller sizes of the regular Final Audio E ear tips (it's $15 for the 5 sizes multipack on Amazon) for wired IEMs should also fit inside TWS earbuds cases. Check Audio46 (this is from New York) if they have the Final Audio E for TWS version in stock.

The dimensions/sizing/measurements/etc. for most ear tips these days will be on Amazon/AliExpress/HiFiGo/etc. Unfortunately you have to blind buy the ear tips in order to get a feel for the dimensions/measurement/etc. that you like for your ears. Remember, this will also change with different IEMs as they'll have different nozzle length, nozzle angle, and so on.

Here's a bit more info on ear tips: https://www.reddit.com/r/HeadphoneAdvice/comments/10k210n/alternative_tips_for_aria/j5o2f8q/

This is how you should use Etymotics or really any IEM or TWS earbud to make sure you have that good/perfect fit for that vacuum seal (necessary for the bass to be properly produced): https://www.youtube.com/watch?v=8KwXEqe6Gq4

For TWS earbuds, see here for more info: https://www.reddit.com/r/HeadphoneAdvice/comments/10hdr2p/are_there_any_wireless_earbuds_witouth/j58keli/

Click through those thread links if you want to look for cheaper (<$50) TWS earbuds for specifically gym/running/etc. use. Look for the ones with IPX5/7 water resistant or waterproof ratings. And ya always wipe the ears and IEMs with a clean paper towel or microfiber cloth so that it doesn't get clogged and also because sometimes the gold charging ports will be covered in sweat/dirt/etc. and it won't let the TWS earbuds charge properly.

AES paper number 5401 is about tones above 22 kHz for speakers.

Everyone can detect differences with played from a single speaker. The paper concluded it may affect sound impression.

Nope. All waves whether audible or electromagnetic pass through each other without affecting each other. Its a fundamental principle of the universe. Just like almost everything in space produces a wave and most of them are undetectable without the right device.

I prefer to un-tether from the desktop to listen to music. As a speaker & over hear headphones guy, these $20 Chu buds are a god send. Am contemplating a DAP.

When I am on the desktop, I'll throw some form of a visual from youtube. Fractals, Kaleidoscope, etc.

Hello fellow ASMR enjoyer 🐐

No, impulse response is the time domain counterpart of frequency response. They both convey the same information but in different domains. See my comment in the thread for a more detailed explanation.

Clearly you have no clue about signal processing. The frequency response (which is one of the only relevant measurement according to you) is actually computed from the impulse response by applying Fourier transform and selecting its magnitude.

Good buy. Just fyi from my experience with customs. Shit will feel tight for awhile. Will take a few days to get them feeling adjusted to your ears

An yet some people believe it is true

OP wanted to know about impulse response, not step response.

Impulse function, δ(t) is defined as function whose value is infinite at t=0 and 0 elsewhere. So, Impulse function can be thought of as a signal which has a uniform amplitude of 1 throughout the frequency range. We give this signal as an input to the system (headphones) to find it's response for all the frequencies. The output given by the system is called the impulse response (the plot you posted). Now, if you compute the Fourier transform of the Impulse response, you'll get a complex function. The magnitude of this function is the frequency response of the system. Audiophiles are usually more interested in the frequency response than its time domain counterpart.

Why do people make comments like this? The OP says they like the sound quality. Why crap on someone else's purchase and opinion?

i was talking about how most people haven't tried the headphones that they talk about, and claim to know all about it; effectively parroting what they read without confirming anything

Man jumped into the endgame right away, nice purchase.

enjoy them! give us a review after.

This is movement of the magnet of the headphone when you give it an impulse signal. Normally if everything were perfect you should be seeing a straight vertical line, but it takes time for magnet to return to its original position. And this graph shows that and with how many oscillations it takes to get there.

Dude, believe it or not, there are people in this sub that have careers AND hobbies and can afford to buy stuff. You don’t have to be “rich”. I’m a normal middle class guy 15 years into my career and since I don’t have 15 kids or some kind of crippling gambling or drug addiction, I can afford to spend money on a hobby I enjoy, just like lots of other people.

$1300 was a lot of money when I was 20, not at 35. It all about perspective, you don’t know anything about OP.
