I don't even think the headphone looks good - the aesthetics - so it's not got the measurements & it's not got the looks! That distortion going down with increased level, albeit was high distortion at all levels, that was an interesting point, I wouldn't know how to describe why that was the case, so that's pretty interesting. At least it's not a British headphone, I thought that with Amir's initial comment on "looks the part" as a British saying was a subtle indicator that it was a British headphone, but thankfully it's not this time (I may also be thinking of some British speakers (or something else!) that measured poorly recently here, so not a headphone probably)!

It's a tough one re what Amir was saying about not knowing why companies create all these headphones still with random frequency responses. I suppose we can't have all manufacturers creating headphones with exactly the same frequency responses (eg the Harman Target), but thinking it through as I type this it's true that headphones need to get some minimums right when it comes to frequency response - it's still got to be relatively balanced frequency response with most areas represented in some way, and that can still be done to an acceptable balance if not deviating massively away from Harman and also if the counterposing frequency response areas complement each others variations - like if a headphone was slightly under represented in parts of the treble then you probably wouldn't want full Harman bass compliance & instead you'd probably want it slightly below Harman bass level - a bit like how the frequency response patterns/balance goes for New Version HD560s headphone in my experience which sounds good at stock. So yep there's still room for headphones to not be exact carbon copies of each other whilst still retaining some acceptable balance to the sound.
 
Oh yeah, those were pretty universally disliked, not sure that's a good thing to copy. In fact, the SRH1540 were some of the most annoying to wear expensive headphones I ever tried.
The 1840s were not universally disliked. They may be the most underrated open-back headphone ever made, though. There are few good reasons to dislike them. Reduced soundstage width might be one, but I would take a more neutral headphone over a wide soundstage any day. I doubt the headphones reviewed at the top of this thread compare with them, although it might be worth buying a pair just to see.

I’m not aware of any more neutral headphone on the market than the SRH1840, or one with a smoother overall response, which makes them perfect for reference-quality mixing, mastering and close listening. An exception to that statement would be the HE-1, which are undeniably better, but hardly comparable.

As a matter of fact, I shopped for years after buying the SRH1840 for something better (because I was seeking the best) and aside from the HE-1, never found it. My speakers are Neumann KH120s and K&H O 300s. I bought them for piano, after hearing the SRH1840. The speakers do not reach the same level of perfection and realism as the headphones, but they are the closest that I’ve found or expect to find for the same budget.

If you have a pair of headphones that measures more neutrally than the SRH1840, let me know. The HD600 is their closest competitor, and is disliked by very few. That people buy the HD600 instead can hardly be a knock against the SRH1840.

At some point I’d like to do a volume-matched A/B listening test between the two with my ADI-2 Pro.

For a long time I wanted a pair of HD 800S and a pair of Dan Clark Stealth. I had a chance to audition both in the same afternoon as the HE-1. The latter were obviously better headphones, in the sense that it was impossible to find anything lacking in their sound, but I prefer the 1840s to either of others. The 800 sounded slightly shrill, rather than detailed, and the deliberate bump in one part of the bass on the Stealth made no sense to my ears.

Among those who appreciate the 1840s is @solderdude who reviewed them favourably. The worst thing he could say about them was that they weren’t needed to replace the HD600, and that their non-linear behaviour at higher decibels counted as a design flaw. Otherwise, he has said they’re very good.

While I haven’t tried the 1540s, the 1840 is also by far the most comfortable headphone I’ve ever worn. They’re light as a feather and you forget they’re on your ears. Perfect for a long session and for realism in general. Potentially even better than the HD600, because they match their neutrality closely, but arguably look and feel better.

Another reason the 1840s were panned by many was their high levels of measured distortion (which nobody could confirm was actually audible or unpleasant). I’ve done distortion tests with them using extremely performant DACs, and the distortion is inaudible.

I agree. So in that respect, and also as far as measurements go, they look like a poor copy of the SRH1840.

Edit: however, the non-linear response and distortion (which may amount to the same thing) appears to be shared by both. Someone elsewhere said they’re using different drivers. But perhaps they are even closer copies than I think.

They can create whatever frequency response they want. Either they follow the research or, do their own to determine customer preference. The issue I have is some random response that has no foundation to be valid. We don't have amplifier with these wild responses. Why headphones?

Is part of the answer that they are only working with a single driver?

No. Single drivers are fine. It is not like speakers where you need multiple drivers.
 
This is a review, listening test, EQ and detailed measurements of the THIERAUDIO GHOST headphone. It was kindly drop shipped to me by a member and costs US $129.

As our British friends would say, the headphone "looks the part." Alas, it doesn't "feel" the part. One touch and you realize this is NOT what luxury products are made out of. It just feels cheap. I did like the thin cables that came with it although I wonder how long they will last. The feel was that of some "hardness" and stiff pushing of the corners of my ears -- not my favorite.

Member had sent me the Brainwavz Angled Pads as well. He said the word is that with them, it will rival that of Sennheiser HD6XXX. Given the measurements below, I highly doubt that. At any rate, I only tested them with the stock pads.

If you are not familiar with my headphone measurements, I highly recommend to watch my tutorial on it:

THIERAUDIO GHOST headphone Measurements
Getting the headphone to fit well and produce similar response on both channels was difficult. I tried everything and this is the best I got for the headphone frequency response:
View attachment 439145

Checked elsewhere and correlation is very good so the bass is indeed drooping that much. As is treble response. If the only part of the music you like is from 150 Hz to 1 kHz, this is the headphone for you! EQ curve should not be hard to develop:
View attachment 439146

I don't think I have seen a headphone where distortion reduces with increased level but here we are:
View attachment 439147
I could easily see the bass sine wave distorted in the measurement panel (it takes a lot for it to look that way):
View attachment 439148
We have a very broad distortion pattern. Not good.

Group delay shows some disturbances but pales in comparison to above:
View attachment 439149

Impedance is low-mid range, meaning you need more current than voltage:
View attachment 439150

Sensitivity is better than average:
View attachment 439151
The combo should make it relatively easy to drive.

THIERAUDIO GHOST headphone Measurements
Did someone turn the audiophile life off??? That was the first impression of listening to the headphone. Dull, closed in, and totally non-hi-fi. If I have heard worse headphone sound, I don't remember it. A couple of filters bring some light back the the "picture:"

View attachment 439152

Given the massive boost I needed for bass, I had dial in a lot of headroom. This counters the sensitivity of the headphone, requiring a proper amp to drive it. With the three filters in place, the sound no longer sucked. While tonality was improved, spatial qualities were so poor that I could still not find words to praise it. By this time my ears were suffering from the hard pads I had to take the headphones off.

Conclusions
I don't know how much longer we need to so many companies choosing random frequency responses. Or is it just whatever they wound up with after they stuck a driver in an enclosure with nary a measurement? Yes, the price is low. If it had the response of Sennheiser HD6XX, it would pass. But it doesn't. HD6XX only lacks bass. This headphone lacks just about everything.

Really bad.

I can't recommend the THIERAUDIO GHOST headphone. Hopefully other than the poor owner, none of you have bought it.

Here are some thoughts about the EQ.
Please report your findings, positive or negative!

Notes about the EQ design:
  • The average L/R is used to calculate the score.
  • The resolution is 12 points per octave interpolated from the raw data (provided by @amirm)
  • A Genetic Algorithm is used to optimize the EQ.
  • The EQ Score is designed to MAXIMIZE the Score WHILE fitting the Harman target curve (and other constraints) with a fixed complexity.
    This will avoid weird results if one only optimizes for the Score, start your journey here or there.
    There is a presentation by S. Olive here.
    It will probably flatten the Error regression doing so, the tonal balance should be therefore more neutral.
  • The EQs are starting point and may require tuning (certainly at LF and maybe at HF).
  • The range around and above 10kHz is usually not EQed unless smooth enough to do so.
  • I am using PEQ (PK) as from my experience the definition is more consistent across different DSP/platform implementations than shelves.
  • With some HP/amp combo, the boosts and preamp gain (loss of Dynamic range) need to be carefully considered to avoid issues with, amongst other things, too low a Max SPL or damaging your device. You have beed warned.
  • Not all units of the same product are made equal. The EQ is based on the measurements of a single unit. YMMV with regard to the very unit you are trying this EQ on.
  • I sometimes use variations of the Harman curve for some reasons. See rational here and here
  • NOTE: the score then calculated is not comparable to the scores derived from the default Harman target curve if not otherwise noted.
Good L/R match.

I have generated one EQ, the APO config file is attached

I mainly see it that Harman Target is a good option for a lot of people (most), and then some people prefer slight tweaks to the Harman Target to get what they think is their best sound but these latter people are really just audiophiles that have experimented with EQ with at least one headphone to work out what their own preferred target curve is. So I tend to think that headphones designed around somewhat subtle tweaks around the Harman Curve are most useful to people or indeed just headphones designed to mimic Harman Target just as good they can. Best sound for everyone is not exactly Harman Target, so a few headphones designed around it but with somewhat subtle differences could be useful to those people if they want to use that headphone at stock - it would be a crap shoot for inexperienced/uninformed headphone buyers though (which it is for most people who buy headphones out in the wide world beyond ASR anyway). Different models of headphones that would measure the same on a GRAS rig won't necessarily sound the same when you listen to them anyway, but they should be really quite similar, so there's always gonna be that level of difference between different headphone designs even if manufacturers all aimed for the Harman Target. I don't think it's that logical that all headphone companies would ever just all aim for the Harman Target because headphone's vary too much in that specific model's interaction with measurement fixtures & real humans such that it is not as definitive in how it would sound to someone vs the Anechoic Flat Speaker standards that we use here on ASR which are much more locked down and definitive than headphones could ever be - so I think there is some intellectual wiggle room for some headphone designers to target even slightly different targets to Harman Target even if they agree with the Harman Target science, and perhaps such manufacturers may do their own testing (rigs & real humans) to work out their best tweak to each specific headphone model. But for sure I'm not in favour of wild frequency responses in headphones that differ wildly from Harman and also when they have no consideration with how they vary from it to retain balance. And of course I also think it's right that the Harman Target is used here on ASR as the target of comparison for the objective measurements.

People’s eyes are different, but you would never say this [edit: I mean that there is “wiggle room” for manufacturers] about colour standards for screens. We need to break out of the audio circle of confusion.

Consumers aren’t going to test headphones and verify that they match a standardized response. Manufacturers and reviewers need to do it. If something deviates from the standard, it should be quantified, and buyers should be informed that their headphones are modifying the signal to conform to a different standard, or no standard at all.

Playback devices should have EQ available to both correct for the idiosyncrasies of a particular headphone model (as with Sonarworks headphone profiles), and to correct for individual hearing differences and preferences.

All this is not nearly as hard to do as you might imagine. Most of it was standardized for video ages ago.

We already quantify it here on ASR with the frequency response vs Harman Target graph, so we've got that covered. Headphones are a bit too variable between different people and rigs though to be totally locked down, so it's not quite the same as saying there should be a set colour standard for video reproduction for instance. If everyone had to listen with Harman Target headphones it wouldn't totally remove the circle of confusion because of that variability I mentioned, but yes it would make it closer - but we're already doing justice to that with the ASR measurements here vs Harman Target. I don't think I'd want to see all manufacturers have identical measured frequency responses for the reasons I mentioned that it's not absolutely best sound for everyone, but I'd like to see them be somewhat subtle variations on Harman Target or indeed Harman Target. Marketing wise, and just for point of differentiation it's impossible that all headphone companies target exactly the same frequency response, otherwise there'd be no point in buying headphone X Y or Z apart from comfort/fit issues, distortion measurements, cost, anecdotal soundstage reports by users, build quality/aesthetics, and degree of unit to unit variation (how tight their manufacturing specs are) which is a current mostly unknown anyway unless you measure a good amount of units - well that's actually quite a long list of potential differentiation if they were to target the same frequency response, but some of those mentioned qualities are not important or visible to average consumer.
 
I have a pair of these. I’m not a regular user of headphones - I use them a less than 25 hours per year. The best thing I can say is that they sound better than my Grado SR125’s.
 
I have to hold my hand up here. I bought these after listening to a snake oil "influencers" review on Youtube.
Sound quality wise I found them somewhat underwhelming which why, I suppose, I have recently bought a pair of Hifiman HE400SE replacements. The Hifimans were under half the cost, are constructed with better materials, have a more comfortable fit and offer a frequency response and clarity far superior to that of the Thieaudio Ghost headphones. Don't make the same mistake as me. There are much better headphones out there than the Thieaudio Ghost, even at reduced pricing.

Thanks for sharing; my experience with headphones is very limited. What other headphones under $300 are better buys than the Ghost? My preamp manufacturer recommends headphones having greater than 50 ohms impedance.

I'd recommend HD560s if you're not using EQ because they're well balanced even without EQ, and if you're using EQ then you could still get the HD560s or Hifiman HE400SE - those would be the ones I would recommend. Actually though the HE400SE has a low impedance around 28ohm so that would be too low for you then. In that case I recommend the HD560s.

Not sure now with the tariffs - but possible the Hifiman Sundara or the Edition XS can I think be got for < $300 and both are pretty good, the Edition XS if you aren't put off by the giant ear cups is pretty amazing IMO. There is now also probably the FiiO FT1 Pro also as a reasonable good cheap option.
