The thing is, those are still more of a perception thing. The physical driver will follow whatever the signal is near instantaneously since it's a minimum phase system. Even between "slow" sounding and "fast" sounding headphones, the driver response is basically identical. So effects of attack, decay, speed, and clarity, are more due to frequency masking and what parts of the frequency a particular driver emphasizes more than another (not something you can just EQ in. Different drivers have unique sounds to them).

I just think the term "resolution" can be misleading to some since it may imply more of a physical difference you can read on a stat sheet, rather than something you just have to hear for yourself to understand

Watched them now. Really informative and actually enjoyable to watch. Thanks for sharing that!

It's just a play on sound waves and wave forms. Music has multiple frequencies, but they're all combined together into a single waveform that the driver follows to create a pressure wave. Then your ear hears that pressure wave and extracts the individual frequencies again

Yeah. It's just a meme based on semantics, that's all. It's producing multiple sounds, just in one waveform. Nothing to take seriously

It's just a play on how transducers make sound. The speaker itself is only moving up and down to generate a single waveform. It's just that the waveform is a combination of many frequencies which our ears and brain is able to decipher as individual sounds

Asking the real questions

Will definitely when I get off work. Thanks

Thanks. I know it's a math equation that I really don't understand. Hoping to learn as much as possible, but yeah my understanding is definitely limited

Disregard my original comment, I misread the comment above, and mine is a poor and incorrect explanation>!Yeah it all combines together through the fourier transform. The movement of the driver is a sum of its frequencies, and even if the driver seems to be moving up and down in a simple pattern, it is doing that as a result of the different frequencies all adding together. Your ear is able to take that sound and through a reverse of the same fourier transform equation, each individual frequency is separated and heard individually!<

Nah but for real, I think the term "Resolution" is misused a lot in audiophile terms since we think of Resolution as a fixed stat. Screen resolution, etc.

In terms of audio, we could call the frequency range or bit rate as "resolution" but that's not what people mean when they describe resolving headphones. They more talking about a perception or how it feels

Sennheiser build has changed a lot. Still durable, but thinner and lighter plastics. Even a new HD600 or 650 next to an older pair (or compared to a current 6xx which uses the old mold), the new one feels cheap and light. At first I even thought it was fake because of how it felt in comparison

>2. Referring to the Harman target and headphones that fit it well as "neutral" when that is clearly V-shaped. Neutral is flat, damnit.

I think when people think of Harman, they hyper focus on the bass, which is meant to be adjusted to your liking. More important to the Harman target are the mids and treble. That's why things like the HD600 are considered as following the Harman target really well, even though it has neutral bass

20hz-20khz

Yeah it's more just meant as a joke on how some react.

15+ more upper mids and treble? We're ascending to the next level of hifi untapped before

I think Soundstage is the most overvalued (me a 6X0 enjoyer)

Listen to them for a few days straight. Your brain will always "auto EQ" to whatever you listen to the most. This makes the difference in sound signature exaggerated for a couple days.

When I first switched to 600s they sounded anemic and lacking energy, but after a few days they sounded very balanced and clear, and other headphones I was used to sounded muddy and really lacking in sound quality

I do think that for your case its probably better to return the Alice. I found moondrop Bluetooth IEMs have sort of a background noise and don't sound the best on my devices. For a reliable TWS, I do prefer airpods pro or Galaxy Buds Pro.

I do like wired IEMs, but fit and convenience is really important

The SE215 is quite bass boosted and something i consider bloated compared to most IEMs and headphones in my collection. So if that's your daily driver, it's important to remember that your brain will automatically adjust and equalize to whatever headphones you listen to on the regular. So if you're used to the 215, anything that has less bass or is more neutral will sound anemic and like the lack of bass is exaggerated. It usually takes a few days of constant listening to reset your brain.

That said, I'm not saying you need to like them. I haven't used the Alice and can't comment on how it's sounds (although usually moondrop is somewhat of s Harman sound). To be honest, for wireless not a big fan of moondrop IEMs, but for wired they're one of my favorites

If there are other issues other than sound that you don't like, absolutely those are important criticisms. But if the main complaint is just the sound signature or tonal balance, I always recommend spending a few days straight using them first.

No you don't NEED an external amp. Unless the headphones are really low sensitivity, you can drive higher impedance headphones from a wide variety of sources. I ran 300ohm headphones from just a little mp3 player or my Nintendo switch. I've also done that with my 250ohm beyerdynamics fine

Either, but yes with the lights off and listening in a dark room does seem to improve my perception imaging in binaural tracks for me

8:1 is just the common middle ground that has been accepted, but oratory goes into it a little more in section 3 of this post https://www.reddit.com/r/oratory1990/comments/ugofb0/why_can_measurements_from_different_sources/

Tl;dr while 8 times is the generaly accepted ratio, there's no reason its specifically that, as even an 8:1 ratio can cause a 1dB difference in the frequency response of the headphones due to the damping factor. so a higher ratio can still be more desired for less of a change in FR

You generally want as low of an output impedance as possible to have a high damping factor ratio. If you use a higher output impedance with headphones that are too close in load impedance (usually any ratio closer than 1:8), than it may have an impact on the headphones frequency response and change how they sound. Some pairings use this for specific changes, but usually you want a generaly low output impedance, even if the load impedance is higher

The blue line is a fletcher Munson curve/equal loudness curve. It's an average measurment of human range of hearing for each frequency.

The curve isn't ideal for headphones or audio as a target, and also changes by listening volume and flattens quite a lot as the volume increases.

The only other person I've seen use the equal loudness curve as a target is nouvraught, although he would do it by first compensating the headphones FR to diffuse field first, and then comparing against the equal loudness curve... not that it's to be taken seriously anyway. As far as I know, it's mostly baseless methodology

I would be tempted... but I'm trying to manage my impulse spending habits better... also new pokemon just came out
