Is Headphone Burn In real Part 2 this time with planar headphones ... Fight me in the comments

[@spudunit]

Before I got planars, when I'd get bored with a pair of headphones I'd switch to a cheaper pair and listen until I stopped objecting to the inferior sound. Then, switching back, the better headphones became essentially new again. What I'm suggesting is that the 'burn in' might take place primarily inside our skulls. Don't discount neuroplasticity.

[@CustomCans]

I like that idea... Learn to appreciate what you have more

[@clickbaitpro]

Or the pad compression over time or burnin is just a real thing

[@warc8us]

@@clickbaitpro pad compression is a real thing, several months ago I replaced the pads on my HD600s and it was like I upgraded to a superior headphone. I'd worn down the stock pads enough that there were gaps where my glasses are and my ear placement was much closer to the drivers than stock.

[@TheIndieGamer500]

This is probably the best burn-in experiment I've seen. Props for coming up with good experimental conditions. The one thing that I think is missing to make it truly scientific is a second fresh out of the box, identical pair of headphones that would be measured at the same intervals on the same source/amp, but would not be playing any noise or music the entire time. That way if some kind of environmental variable was responsible for the change instead of the pink noise you would be able to identify it by also seeing a change in the headphones that didn't play any noise. But I understand that requires having a second matching measuring rig and opening more headphones, which is double the amount of setup and materials. Thanks for sharing your methods and findings!

[@CustomCans]

Yes, if I am brave enough to upset more people, I will do that next time. I was thinking maybe disconnect the right side of the headphones so the left side gets burnt in and the right side does not then measure them both to see if any other external factors caused the change.

[@TheIndieGamer500]

"It's suspicious how we only hear about burn in where the headphones get better." I've said this in the last video, but they most certainly can get worse. I've ordered 2 pairs of Fostex T50RPs which started to sound different in the left and right ear over the course of about 1-2 weeks. I don't think we usually hear about it, because people usually just return defective headphones.

[@1000dreams]

Headphone burn in is probably too subtle for me to notice, I'm more of an emotional listener and not an analytical listener. I do have a deep passion for music though. I also have this weird thing where I can't listen to lyrics either, it doesn't matter if I listened to a song a hundred times. Though I can feel deep sorrow or joy when I listen to music, or feel lost, adventurous, homesick, whatever the music conveys, it's quite strange. I can also remember music and replay it in my head in deep detail, but I can't bring back the lyrics, lol. I do have diagnosed ADHD and bad case of Misophonia, maybe there's something else too. Anyway that's on the subject of being able (or unable) to discover a change in the sound when it comes to burn in. You already mentioned some of the aspects that might assist in the matter, pads breaking in / getting softer and bringing the drivers closer to the ears, maybe changing the angle ever so slightly, the metal parts finding their ideal 'state of being', I think the buildup of oils and sweat also prolly affect the seal, the same with the variance in ear-wax in the ear canals prolly play a role and I wonder if the air pressure caused by the weather might play a role? Your graphs do show a measurable effect in a controlled environment, so I think that's a good take away and it makes logical sense. Thanks for putting in the work! My input is prolly that the listener's emotional state, mood, personality, mindset and things like that play a role in how music is perceived through different headphones and in moments of life. When one is grumpy and irritable for example, perhaps that one pair of headphones that's just a tiny bit hot in the treble but is usually perceived as being sparkly and extra detailed is now kinda shouty and annoying. So, burn out seems to be real, but the extent of the perceivable difference is strongly variable depending on the listener. And the placebo effect is definitely a thing, the remarkable thing is that placebo's can work even when people know it's a placebo. Human brains are extraordinary!

[@johnpulliam3307]

I only use one ear bud at a time so i am willing to try allowing one Side to sit idly by while the other goes through a rigorous burn-in process to be able to actually test them side by side to compare the results.

[@CustomCans]

Good idea

[@BionicSammich]

What gets me going is when people say burn in totally changed the way their headphones sounded. I've read posts online how their headphones went from being super trebly to fairly dark and smooth sounding. I just don't buy that. A dB or two here or there, understandable, but not a complete change in tonality. What really gets me is cables and people saying they change the sound drastically like a silver cable making it brighter or a copper cable making it darker. I have a set of Meze Elites that came with one of their Copper PCUHD premium cables and a mate of mine has Empyreans with a silver PCUHD cable. We measured both sets with the stock cable, the copper cable and the silver cable and there was nothing outside of the margin of error. Are those cables pointless then? no, they fell great and are nice to have. Just like the handful of Custom Cans cables I've had for other sets of headphones. They don't sound any better or worse, but just enhance the experience with their looks and comfort. Maybe it would be different if the stock cable was sub-par or something. So any Meze Elite/Empyrean users out there, save your money on the Meze cables and buy a Custom Cans cable!

[@CustomCans]

Yes, it is definitely not a night and day change. To be honest I was not expecting it to be noticeable on the graphs. As for cables .... Yes, I know we get a lot of feedback on our cables saying that they improved the sound but I suspect, unless the cable they were replacing was really bad... the improvements will mainly be in looks and ergonomics and any psychological benefits that brings.

[@Hijynx87]

Oh for sure, if it’s real it’s only a db or less here and there. Maybe the bass tightens a bit. As for cables, I haven’t really taken the time to a b on my iems, I usually try to match color or like the feel. Stock Hifiman cables are dog crap bad lol, like a catheter.

[@andysledge]

placebo is insane and real

[@LDWilliams]

I feel that the thing about this is this, Are the small differences in the graph readings worth you Not enjoying your cans immediately? If so, great for you, if not then 'burn in' will occur naturally anyway and the sound will improve for you over time.

[@impuls60]

To me it proves that the changes are small. With speaker drivers the Fs always changes a few Hz lower with burn in. For fun you could have shown the results completely unsmoothed, I think the absolute peaks would be higher after burn in because of the lower stiffness in the "suspension" if one can call the membrane that^^. In some amps the transistors behave differently warm than cold, but obviously not in your amp :) All in all a very interesting video!

[@CustomCans]

Thanks and yes... the changes are very small but there does seem to be something in it

[@BlueTJLP]

@@CustomCans Are they really as small as they look like on the graph? Or is it like an EQ where by putting more emphasis on the bass...for the same volume as before doing that adjustment, bassy frequencies are more in the foreground now and other frequencies are more quiet in direct comparison? Sorry, it's a weird way of putting it. But what I'm trying to say is that if the line on the burnt-in graph is a bit higher in the lower frequency range, for example, it affects all other frequencies by making them stand out a bit less. On the surface it may look like a small change, but in reality it affects the whole sound.

[@Raikos100]

​@@BlueTJLP Just like EQ, one point in any frequency up or down you can definitely perceive the difference, even if small, tho it doesn't do much overall, if you are very sensitive to sound frequencies (I do) it can be day and night.

[@FullFledged2010]

The earpads getting wornin and getting softer also has a huge effect on lowend. Try and press your headphones against your ears and behold how insane the lowend gets. If you wanna test this you'd need to measure the exact distance the pads get squished with each test.

[@CustomCans]

On this test we 3D printed solid pads to stop that from happening

[@hartyewh1]

I wonder how big a change that is percentage wise. In the highs the second measurement is also a but tamer and 2dB below 50Hz is noticeable with the right music for sure.

Thanks I won't comment too much on burn-in but I would like to talk about how it rolls of at 60hz I'm not saying music does not reach that low I do know some music actually makes use of such frequencies but wouldn't that be a good reason why people don't really notice the difference in burn-in? like there are actual people who couldn't hear properly below those frequencies and let's not forget not all music makes use of such frequencies and that is "deep" sub-bass territory which in my opinion it's that part of the music spectrum where you just "feel" the rumble rather than actually "hear" the rumble If it rolls off at around like 150hz now that should be noticeable to everyone so my point here is it probably really depends on each individual if they can HEAR that low and the TYPE of music they play of course being a somewhat objectivist but also subjectivist on certain aspects in audio I would just like to note that just like any other medical research or Thesis I hope more people would do a similar test after all we can't really make a conclusion on just one test from one person (btw this is not me questioning the video this is me proposing to actually make this topic be done once and for all) EDIT: I would also just like to add again that the topic about it rolling off at 60hz gets even worse if your headphone like an open back is already rolled off at those frequencies meaning you already have a hard time hearing that low by default doing burn-in or for that extra 2db increase at 60hz below probably is not gonna make a difference the most noticeable case for this would probably for IEMs and those who play like hardcore bass tracks but like I said it's probably dependent if you can actually hear that low and the type of music you play

[@chungang7037]

During the audiophile dark ages (early 2000s) I had no money and did way too much research on what headphones to buy. Forums on the HD600 even had burn in stories, from people who were into house music and other genres with a lot of slamming base where they claimed the drivers loosened up over time and they were able to enjoy the headphones more. Fast forward 15 years, you rarely hear about the HD600 anymore, much less so among base heads. I often wondered what that would do to a driver, if people were listening at high volumes with a lot of base over time. Would pink noise have the same effect? Anyway, great video~~

[@CustomCans]

Yes - I have heard about it for years with people very passionate on both sides which is why I was trying to confirm / disprove it for my self. I am still not 100% certain but it is starting to look like there could be something in it

Thanks - I am hoping to do the third and final episode next month with lots more tests

[@Viewer13128]

I would like to express my appreciation for the scientific approach taken in this study, which has been the most rigorous and well-conceived methodology I have encountered thus far. I have always been saying that the science guys who claimed burn-in was false ALSO lacked a study with "proper" or "satisfactory" methodology to actually have high validity, and had been proposing a similar methodology to test burn-in. Your method is the best methodology so far, and when you address the few limitations brought up in some of the comments here, it will be even better. But as of right now, this video here is the best so far. Up until now, neither camp had science backing them up as far as I was concerned. The against camp simply had a bunch of theories that were untested/tested with poor methodology. They would provide theories on why rigidity loss can be real, but claimed it won't affect sound, without actually testing it. Or, they would claim measurements are inconsistent, or differences (e.g., 1dB) are not significant. I would suggest, for the sake of it, that in future tests, a lot of measurements be taken each time to demonstrate that they all graph the same at a certain point in time without even a 1dB difference 10 times in a row. This is the only test I've seen that I would be willing to call a test with sufficient validity. It's the best one I have seen and I look forward to your future one.

[@CustomCans]

The instructions booklet in the HE1000Se box says burn in 150 hrs

[@dasninjastix]

I'm perfectly fine with the "placebo effect" here being ascribed to burn-in as "it can't hurt" or "you think or expect there will be an improvement after burn-in, so there's an improvement". No issues with that context. But that's different from representing burn-in as different states of rigidity or tension with the driver creating noticeable and beneficial improvement over a certain number of hours of playback. Let's say that burn-in is 100% applicable and is always beneficial - I would then contend that the ability to perceive the differences or benefits is going to vary WILDLY from person to person as we all hear differently, we're all listening to our own music preferences, through different software or hardware, and at different volumes in different environments from one another. Attributing positive changes over time to burn-in continues to seem like an oversimplification of the listening experience. And it makes sense why a manufacturing would want to stress a driver either for QA or for tuning. Why wouldn't you want to know how the driver will respond over time? But whether that will make an audible difference to your average listener.. seems like it would depend on a multitude of factors not just the wear of the driver or its tuning materials over time. I would be willing to bet serious money that an stealth increase of 2 to 3 db in volume, from a first listen on a Monday to a next listen on a Wednesday, after some 36 hours of burn-in, would result in all the glowing language you hear from burn-in evangelists. I think I'd also wager that mood and general comfort have a bigger impact on sound perception and enjoyment than burn-in.

[@CustomCans]

Yes - I think this shows that if there is an effect, it is very small and probably not noticeable. As you say - my memory is not good enough to remember exactly how something sounded 48 hrs after my initial listening sesh and my mood / how hungry I was would probably have more of an effect of whether I thought they sounded a bit better or not ;)

[@hartyewh1]

The only burn-in experience I'm rather confident in (wouldn't put money on it, but would whine at strangers online) was the M50 I bought as a teenager. I went to test them several times and for about two hours when I finally bought them. I tested with certain songs and when I got home to unbox my very own unit and play the same songs with same volume I found the sound very harsh (even for an M50). It was apparent in under 2min of listening. I freaked out that I wasted my money and went online where I heard of burn-in. I left them play over night and voilá! In the morning I was immediately pleased with them. Either brain burn-in happened much faster then I would expect or something changed. My theory is that the rubber ring holding the driver loosened a bit since that could make sense. About the best sound to play for burn-in. I would assume something causing the most movement would be ideal as in a big and fast bass beat, no? If something changes then it has to be mechanical so why would pink noise be better?

I would say he was going about it pretty scientifically, as a first start. And I'm a scientist. He did show that there was a measurable difference. Now he would need to validate his findings by controlling all factors he didn't so far and take more samples/measurements at each step.

Our objectivist messiah NwAvGuy tested this 13 years ago with a Sennheiser HD 650 where the resonant frequency in free air moved down a couple Hertz after 48 h of break in. That way of showing break in was smart because with a free air impedance measurement all these coupling variances have 0 influence. I think in your case the silicone of the miniDSP started to give a little after a day which made the seal ever so slightly better. Of course the tension on the diaphragm will also be more loosy goosy. While we're at it temperature should also have an effect on the stiffness. Would be cool if you could stick the headphone in the freezer to see how much that affects it :) The PET will also soak some moisture and the glues air out. Pad wear and unit variance should outclass any of these effects by a mile though.

I’d say doing the test again on dynamic drivers would be an obvious next step. But instead of the pink noise, I’d run the exact same frequency sweep over and over to ensure each frequency had equal exposure through the driver. I’d also suggest keeping the cushioned pads and putting double sided tape on them in case the solid cup had any resonance on the (I’m guessing plastic) ear.

Burn in cannot be real for the simple fact a driver would fail almost immediately if it's elasticity changed so easily cannot reproduce sounds repeatedly.

[@CustomCans]

You may be right - I have a few more things to try before I will be convinced either way.

Very dumb logic( or the lack of ) you got there. lol

@@guybuddy1 For instances, the He400se have a total harmonic distortion below 1% at 105 dBspl and according to rtings their average standard deviation is 0.34 dB. This means they don't distort and they play accurately all the time, and this is not a planar thing, dynamic drivers produce similar test results. Considering drivers easily vibrate billions of times, I don't think it is logical to assume that their properties change so dramatically and so quickly otherwise they would end up failing the strict parameters they are rated at and eventually fail.

Is it a thing? Yeah absolutely. A driver diaphragm is just like a pair of new shoes. Takes a little bit of use before they get properly loosened up and comfy. Does it matter and should you hold off on using your new headphones till it's been done? No. Who gives a shit. Just wear them and they'll come good in their own time.

Wasted opportunity. Let it go longer. You will see more difference on treble

[@CustomCans]

I would not say wasted... I learnt a bit more while making this video. Also... we have an actual business to run and only one test rig so I can't have it tied up for too long. For part 3 I may make / buy another test rig so we can let it run for longer under test conditions

[@ibzman1393]

@@CustomCans I didn't mean anything by it. Just thought that as you had done all the hard work, could have let it go a bit longer, but yes next time. Muchappreciate your efforts. Thankyou

[@towsifshahriarshovo]

Yup,I told you burn in is real. Make a another part of the video, that video burn the headphones for 72-100 hours. That's gonna be interesting.

[@CustomCans]

When ever I do this kind of thing it gets people all worked up so I will give it a few months few months before I give it another go ;)
