I'm not sure. There doesn't seem to be many measurments of it.

Here is HobbyTalk's measurment of it, unfortunately he doesn't have the same Harman target to compare, so this is comparing with the Truthear Zero https://hobbytalk.squig.link/?share=Hobby_Talk_IEM_Preference_2022_Target,JBL_Endurance_Run,Truthear_Zero

Compared to mine with the truthear Zero https://suporsalad.squig.link/?share=Harman_IEM_Target,JBL_Endurance_Run,Truthear_Zero

I wonder if maybe there is a bit of difference with leakage and the coupler. I'm using just the 711 coupler with the metal end for IEMs which is similar to what crinacle uses. I believe Sean olive measured his in a Gras 45CA with the pinna

It's worth noting that the 8khz and 16khz peak are common artifacts of the measurement coupler. The Gras version of the coupler has damping to lower those artifacts for measurments

I bought these after Sean olive posted the graph of the ones he bought, but mine sounded different than what he graphed. More bloated and peaky. When I measured mine they graphed like this

I wonder if there's some variation that isn't clear on the packaging or something

I can't remember, it was a while ago, but it wasn't too much

When it was delivered to my door, I did have to pay a bit extra

Friction mainly. It takes extra work. For each headphone and cross different devices.

I think that's the main reason. Many prefer just plug and play. I like EQ, but even I only use it on devices that save the EQ profile on them like Bluetooth headphones

Same. The 7hz zero has a little too much upper mids-low treble for me which makes them a bit fatiguing

Got good things

Truthear hola finally arrived. The box was crushed. Taking it out, the pouch containing the iems was pressed so hard into the tips that it left indents on the pouch. Luckily the IEMs themselves seem fine, but it's annoying. Oh well, now just to listen to them. Hoping for good things.

Mine came black

Yeah I don't often EQ unless it's something that can save the EQ like TWS. I do think they sound better than the Aria and galaxy buds pro, which were my main comparison for them. But other more expensive IEMs I do think still sound better

Yeah they do have dips from 4khz- through much of the lower treble, then it comes back up in the upper frequencies. Many important frequencies for drums do end up sounding a touch masked, although EQ seems to fix a lot of the timbre issues there. Otherwise on those tracks with drums yeah the resonance from drum hits do sound a touch muted, although still better than a lot of budget IEM which for me tend to be too boosted in those frequencies, causing fatigue to my ear.

Yeah shipping was definitely not as good as other brands I've ordered from shenzhenaudio. Normally tracking is decent and it comes in a week. But both truthear's I've ordered took over a month and tracking said it was going all over the place.

People seem to say great things about the IE200

Normally when I receive a headphone or IEM, I use it for a day or a few hours, get an impression, and make some measurements before I write a review here. Usually, I post a review the day after receiving it

In the case of the Truthear Hexa... I didn't do that. I received them late in the evening, and decided to bring them to work the next day to get an impression of them then... and I haven't stopped using them since. That's not to say they're the best IEM in my collection, or that I prefer them over stuff like the ER4SE or Blessing 2 Dusk... what that means is, I've been choosing to take them to work everyday over the other options I have.

I work as a flooring installer. There's a lot of movement and sometimes loud noise (I wear earmuffs when needed). For the longest time, even though I have a decent collection of IEMs I have always chosen to use my Galaxy Buds Pro over everything else. They sound good enough to compete with things like the Aria/Starfield, and Dunu Titan S, but in a more convenient package without wires. I have other IEMs that a much prefer the sound of like the Blessing 2 D, but I don't want to risk ruining them on a job site.

Well the Hexa did a few things that surprised me and made them the IEM of choice for work. They sound really good. They have a similar sort of signature to the Aria, but they also have a little less muddy sound to them and more controlled but clear treble. I'd describe them as neutral bright, but with sub bass. The instrument separation comes across a lot more defined than things like the Aria or Galaxy Buds Pro, but also not fatiguing in the treble like I've experienced with other IEMs.

Sound wise, it was enough of an upgrade over the Galaxy Buds Pro to motivate me to use them, even though they are less convenient being wired.

The other reason I felt comfortable to take them to work is because they feel sturdy and durable. The main shell of the body is a hard plastic with a bit of a matte finish, and then what I believe is an aluminum back plate. All together it feels very durable, but still light. As well they in my opinion I like their understated look. Being all black with the angular lines, I think they look premium, but still not overly flashy, which I appreciate for a daily/work IEM.

Overall, I'm very impressed. I don't have any measurements this time because, I just remembered now that I haven't reviewed these after using them for almost 2 weeks daily. I just really enjoyed their package as a whole. I'd say it's good if an IEM is enjoyable enough you forget you meant to review them

Waterfall plots are misleading when it comes to headphones, since headphones are mostly minimum phase, the "decay" from a Waterfall plot is directly linked to the FR. You can see this if you EQ the headphone or just shift the headphone on the measurment rig so the FR slightly changes, the "decay" will also change equally with the FR change.

Waterfall plots are designed for speakers and room treatment, and they work for that since it's measuring in different conditions, but for use in headphone measurements they can be more misleading rather than helpful if viewed the same way as waterfall plots for loudspeakers

Are you claiming that Amir doesn't take extra care to have a proper seal and make sure that variables like pad wear are accounted for? /s

This is a good article on the topic https://www.soundstagesolo.com/index.php/features/313-is-it-possible-for-headphones-to-sound-fast-or-slow

Eq?

Typically a headphone with a boom mic is called a headset. Designed for long use as a communication device. The mic is on the arm so you can move it to a comfortable position and talk clearly.

Headphones (Typically Bluetooth) that have the mic built into the side of the cup are more intended to be used for phone calls or short conferences, but not meant to be a dedicated communication device

I will admit that even with my wired collection, 99% of the time I'm using tws buds or Bluetooth headphones for the convenience, and also so I don't have to use adapters if my phone is charging.

Removing the 3.5 jack from phones, and now tablets and laptops is really harming the convenience factor, but I hope it will come around and the 3.5 jack will be brought back

Congratulations. Really these do stand out to me as very good for the price, even in today's market

Huh? They are removable. Or do you have some vintage ones or something?

Glad to see some love for Steins; Gate

The funny thing is a lot of these old headphones that are between 1000-4000ohms are meant to be run on crystal radios. No external power, just the energy in the radio waves themselves are what supplies power to the radio and headphones

Revert back to 4000 ohm headphones to get sound and power from radio waves
