Truthear HEXA Teardown and inside look! Related to Zero? Related to Khan? IEM Destruction!

[@KayBeattMusic]

It's so fascinating to see how something so small can produce sound that changes the competition in such a vast manner. I guess that's the magic of knowledge and development. Amazing teardown video!

[@Krinblacksnoww]

it's actually really interesting to see this teardown and how much engineering actually goes into these things. also, i like the clear-coat look, lets you see the internals. Cool

[@taipan75]

Superb tear down. Learning so much... Big Thanks...

4:55 Two words: "Inverted Polarity" 🤫

[@jackwaau]

It is deliberate. It forms a crossover attenuation of same freq from drivers. Back in the day, cheap speakers used this, so they didn't need an elaborate crossover.

[@LuciferArc1]

These seem like they are really carefully crafted. Cause it sounds like one small adjustment out of place can completely alter the sound of iems. Didn't know iems were so sophisticated in their internals

[@mikeoddone3620]

Inverting drivers polarity it´s not weird at all. Pretty common for compensating xover phase shifts...

[@hi-friaudioman]

True, I wasn't sure if that was a thing or not. I do it in my 1+3 iem. I invert both mid-range BA and I've had good success with it but it's rare that I've seen it in iem's.

[@keithberrytv5425]

i usually hate when people destroy products, but this video was rather entertaining/informative.

[@Criiies]

So.. what happens to a normal user when something like earwax or lint eventually blocks that tiny hole the DD has?

when i install in the fliter tip how can i distinguish knowles damper front side or back side? for example:my westone b30's damper(red one) the side of the arc its to the in side but another iem um pro 30's damper (white one) its another side. what a interest. 17:32 BQEYZ Autumn also have similer design. from Taiwan hi-fier, like your video bro.

[@HKS-le3hi]

Great job as always. maybe i ask if the glue that the BA used has some sort of green-ish / brown-ish nature to them? i think delta fyre mistook that as oxidation.

[@hi-friaudioman]

Yeah its a brownish glue. It's some gross stuff and definitely not oxidation.

[@zaraizara2794]

The Acoustune HS2000MX MKIII features a single dynamic driver and is priced at $3000. Its sound quality surpasses that of most IEMs on the market, even those with over 10 drivers and those with significantly higher prices. Having multiple drivers doesn’t necessarily guarantee better sound.

[@hi-friaudioman]

For sure. That's why I've always been interested in single DD. coherency is top notch and depending on the material and stiffness resolution is on par with most hybrids. It's just more difficult to achieve the same tuning with a single driver due to resonances in the cavity.

[@kqzchungus]

i cant open my hexa for the life of me, u popped it open so easily buyt i really cant seem to open it ive tried everything

[@Dartlin]

Super informative 🙏

[@rickoneill4343]

Those wires are "backwards" for inverted polarity. It helps strengthen the waveforms.

[@maxt.1726]

Great work thank you HiFri👍👍👍

[@Chevalerie2cool]

what's the tool you used to pull the dampener out called

[@JonesBrown-hy8cs]

After reading your review, I'm going straight to the order!

[@ezrabrownstein3237]

Yeah the Hexa is known to have fully inverted polarity. Big debate over whether it's a bad thing in terms of sound.

[@Gabrielnfs]

Objectively speaking it's at the very least wrong and a bad practice. Subjectively speaking it's arguable whether or not it's that big of a deal. I'd prefer if they just got the polarity right.

[@kweekeongthen8470]

at least let consumer know your product are reversed polarity not follow original recording. People can choose which tuning are suitable. Some people may prefer original red apple, some may prefer uncorrect blue apple.

[@superdominator2010]

​@@kweekeongthen8470 but you can just plug a cable the opposite way and a problem will solve

[@kweekeongthen8470]

@@superdominator2010 problem is i suggest people to reverse the cable to test. They think i am crazy people who like uncorrect polarity.

[@SSAMGS]

@@kweekeongthen8470 The problem is reversing the cable wouldn't really work for fixing polarity for hexa since not all drivers are inverted and reversing the cable would just switch which drivers are inverted

[@cheokshunwen6938]

can someone tell me thefull name of the null style dampener tool i cant find it

[@urgi4500]

i dropped mine upon opening them up unfortunately. i tried listening to them and they sound normal to me, surely they can take a fall and remain undamaged right?

[@viderethevaccinatorfromhol7536]

Just asking. Why not some kind of membership or patreon? Your videos are a lot of work and so much better than most "review" channel's. So maybe you can invest in some more high end teardown stuff. Or somewhere around the €500,- market to start. 250 -500

[@aaronmagdaleno2250]

Is it possible to remove the stucked pins in the iems when opened?

[@muralidharan2703]

My truthhear hexa connector pin was broken and the remaining pin was stuck inside the headphone, can you help me for how to remove that

[@giuseppeburmeister6009]

Same here, did you figure out a solution?

[@tinydiccbandito4953]

I feel like one of the drivers in my right monitor gave up. There is an imbalance where the left sounds much fuller, probably the mids BA died. I have already eliminated the cable or the dampers as the cause. Will have to measure them. Sooo… should I open them and try to fix em or will I destroy the casing or the internals?

[@LISTEDGames]

Are you gonna check out 7hz legato?

[@sagaman4785]

7hz Legato looks interesting, bass canon, but looks well tuned. A review and tear down would be great! The Simgot EA 500 would be a good one to review as well.

[@sD-lo4sx]

Good information, thank you so much

[@Ethan-mw1qx]

How would you go about opening a mental shell like the moondrop aria? Some heat and pry? Would heat damage the driver?

[@hi-friaudioman]

Heat will definitely damage the driver if too much heat it applied. You can try leaving them out in the sun for a couple hours which shouldn't hurt. Also I recommend buying a razor knife to split the seam. It's a little dangerous to attempt but a razor knife and a small hammer work well with heat. This is how I open 90% of my iems and it works well but takes time to figure out without accidentally cutting yourself or getting metal in your eye so just be careful.

[@Ethan-mw1qx]

@@hi-friaudioman Awesome. Appreciate your videos and response. Always interesting to see all your different tear downs, not a lot of documented footage elsewhere.

[@pliedtka]

Cool. I just gonna buy Hexa to see how much I can improve the tonality - lower the mids. I'm pretty good at loudspeaker crossovers, but headphones might be a little different without specialized CAD.

That's array driver or series installation it's supposed to be that way as far as I can tell.. Tell m if I am wrong and why as I have done this before in a small Bluetooth speaker I made

[@veltruski]

Inverted BA could be here just for tuning purposes. It might tame the DD a bit. This could be easily tested with a mic and software to show a graph with both, and single drivers active. Do it. Your channel will grow.

[@FatOnAxis]

Naa Inverted does not show in magnitude response.

[@veltruski]

@@FatOnAxis but it attenuates the overall frequency curve. It "irons out" the sum of frequencies.

@@FatOnAxis I know you cant see it It affects the overall frequency. If it's used like that. You wouldn't be able to see it, but it would affect the response. Unless it's mute. Then it's there just for show.

[@bwloawesome]

I wonder how hard it'd be to 3d print a new faceplate. Great video

[@genaishivatov1737]

Hi-Fri Audio, I had a KZ PR1 hi-fi version - annoying high frequencies interfered a lot, now a balance version has arrived - with high frequencies more or less, but massive bass often interferes. Is it possible to somehow reduce its mass - add compensation holes or in another way ??? Thanks in advance.

[@hi-friaudioman]

If the bass is interfering you can try to use a needle to carefully poke the hole in the front to vent the bass, however this is irreversible and you can damage the driver if you poke too far. You can buy a dampener set on aliexpress if you make the hole too wide but they have to go on the outside of the shell and sweat and wear can make them fall off but they're pretty cheap and last a little while. You can also try changing/adding more dampener on the back of the planar and that might help the bass. This is the safest way to tune the bass but you will have to remove the faceplate to reach the back of the planar.

[@genaishivatov1737]

@@hi-friaudioman and if you make small holes on the faceplate - a little bit, a little at once - but a few ???

There is glue holding the faceplate too, also yeah the dampener makes a big difference when removed. It will destroy the bass though.
