I love the color coordination of the pink macbook+salmon t-shirt next to the silver macbook+white t-shirt

It is so surreal to me that a $3,499 can be that fragile in such a goofy way

I think I know what’s happening. You have two processors in the front of the headset and they generate heat when in use. That heat is causing thermal expansion of the glass and then the aluminum has a bit of flex when putting it on and off and over time….crack. Apple should have ditched glass and aluminum all together and used plastic. It would cost cheaper and made the headset lighter.

If the air intake is on the bottom, isn't that precisely why the crack might start there? The rest of the device gradually heats up, but the area directly around the air intake would be colder and thus not expand at the same rate.

11:34 "this looks gross to hold" 😂

Temperature differential on a glass plastic screen sandwich that is under curvature stress. Just like on car windshield and you get a rock chip near the defroster vents. Your windshield will crack as soon as you turn on the defroster on a cold winter's day. Top of the windshield is freezing cold, but the bottom is warmed.

It's almost as if Glass in the front was a stupid idea

Well, it could just be heat from a standby bug while the vents are covered and in the case, I think the major part everyone is ignoring is that (if you’re using the solo knit band) do you have to have adequate pressure to keep it on your face. That is coming from both sides. Think about where that pressure might be pulling the glass back and where that might create a weak point… right in the center of the front glsss

Crazy to see how MKBHD is referencing the Gizmodo article which is referencing my cracked AVP lol

Maybe the cracking is caused by the different thermal expansion of glass and aluminium. That’s why concrete is used only with steel because they have the same thermal expansion coefficient.

Might be because there is a piece of metal between both sides of the glass(the nose bridge) and metal expands when heated, so it makes sense that it would expand pushing both sides apart causing it to crack right down the middle

First gen product baby!

Quite possibly temperature, they are combining metal and plastic like that, just carrying that outside in freezing conditions and coming in and putting it on would be huge temperature gradient

Started from the bottom was said so many times that I'm glad someone said "now it's here" or else I was not going to be able to sleep tonight.

the crack coming majority from the bottom and the air intake there as well cooling that lower half of the glass. the top of the glass is warm and that can cause extra stress on the bridge of the nose. add in what yall said about the lidar could that be heating the glass in a very small space while surrounded by air cooled glass. they would need stuff like those little black dots around your cars windshield to dissipate the differences in temp across the glass.

APPLE going to say it's y'all fault 😂😂

Listening to any defense of this is gross.

I’m curious to hear if people who have the crack use the original headset. The original headset pulls very hard on both sides. I wonder if that along with the heat others are mentioning could be enough to cause the crack. The secondary headset distributes the weight so that the back strap doesn’t have to be as tight. Just a thought

the aluminum expanding slightly and cracking the glass makes the most sense to me. and it might not even be the software turning off properly. i could just be the temperature of where the user is versus where the vision pro was manufactured.

just use polarized glasses to look for tension

Can you over tighten the headband?

Wait is there no warranty in the US? In Germany you have 1 year of free warranty. Also in the first 6 months apple would even need to prove that the customer damaged it if they didnt want to replace it for free. Edit: Its actually 2 years in the EU. Not just 1 year

Wait a minute... A brother in there with y'all now? Shiiiiid lemme start watching again.

My question is: Do you think this is serious enough that KZfaqrs and other promoters should send the word to the public, "Don't buy Vision Pro until Apple addresses this" to force Apple to make a move, or at least address those with existing cracks who might be falling through the gaps, or don't qualify for exchange/refund.

Most of the broken ones I've seen have been from people that put the Vision Pro in the case while they're charging the battery. It makes sense to me that they just don't shut down all the way, get too hot, and the glass cracks at its weakest and most complex point. It's also possible the glass is not perfectly shaped for the frame and just has too much stress in the center, made worse by the fact that it's only adhered to the edges and nothing else.

I learned the difference between shepherds pie and cottage pie from a Gordon Ramsay Kitchen Nightmares episode 😂

Don’t forget about the cracked MacBook Air screens. That Apple ignores.

I've always used a Tech21 case with my iPhone and they aged great. The only issue I had was an old one that kind of started to decompose in a drawer, but that was on my old iPhone 5C, so after like 9 years of iPhone protection I don't blame it for giving up.

Could it be the headstrap is too tight and bends the glass to crack in the middle?

In Australia that is an easy replacement under consumer law. It seems like the layer of glass which is covered by a plastic film, was mad of 2 pieces. Maybe this is why it needed a plastic film on the outside (unlike Apple). It seems like the join is cracking.

I believe the nose area shape is causing internal stress on the glass the sharp bends by the nose may be to much for some glass where the glass structure is not as stable

I had the Apple leather case on my iPhone 6 Pro. Yep - picks up a certain 'humid' crud after a while. I'll avoid the woven cover too... I have a soft clear case, did not yellow (4.5 years) for my 11.

I loved how knowledgeable Ellis was on the glass stuff.

Apple's response is : You are using it wrong

My guess is that the crack is caused from over tightening the head strap. The weight makes it uncomfortable in an attempt to find comfort you over tighten the strap. The thinnest part of the frame where it will bend from this lines up with where cracks at happening.

In Canada the spigen zero one case was only $20 and it’s amazing. Strongest MagSafe and protects the phone pretty good.

Woahh they got another brother✊🏾

Few people are having this issue. And I really question what in the world they are doing to make it happen.

The nose curve is a very tight radius so it suffer from stress concentration. The sharper the inside radius of a material, the worse the stress concentration and fatigueing (thermal expansion cycles are a great source of these) over time will cause cracking and breaking. This issue is precisely why airplane windows have very rounded corners and not as square as in the past (de Havilland Comet distruxtions in the 1950s).

7:45 The nose arch is probably causing a higher stress concentration in that area. Wine bottle divots and wine glass rims are continuous symmetric shapes which add strength because of their continuity, which distributes stress uniformly. Notches are a different story--they tend to produce stress concentrations. My guess is that this is a result of coefficient of thermal expansion mismatch between the aluminum and glass, combined with heat. Glass and aluminum do not expand the same amount for a given change in temperature, and this is a fairly fragile contoured piece of glass bonded to an aluminum frame. This is a much worse scenario than a phone screen, because a phone screen is a flat piece of glass and the thermal expansion produces in-plane stresses. The shape of the VP, however, will produce tensile and bending stresses in the glass as that expansion/contraction happens.

I wonder if one of the headbands are pulling the glass more than was intended. Are the cracks showing up more on one headband type than the other? Maybe the over the top of the head headband was rushed before testing could reveal this issue. Maybe the amount people are tightening the headband is too much?

8:00 WRONG, here's how it works: Imagine a circle, it easier to break out from inside the circle but harder to break into the circle. That's how curved reinforcement work and that's why that middle part of vision pro is structural weakness

Not sure exactly how, but there is a method to check where the tension is on glass. Something with polarised light.

It makes sense it starts from the bottom . The top gets warm from the exhaust heat and expands slowly. The colder bottom, at the "pinch point" no less, gets stressed from the expansion at the top, until the glass fails.

I own one, and from grabbing it off my face and not being perfect about doing it from the middle, I bet it’s from grabbing it on the side and it twisting from the bottom up while taking it off.

i bet the crack is caused by over tightening while wearing

If the air intake is at the bottom, outlet at the top. It could be that the bottom cools more rapidly when the cooling fans kick on. Thus more shock. Immediate temperature changes love breaking glass. Whereas, the air is preheated by the time it reaches the top of the device, thus the cooling isn't as rapid or damaging

Meanwhile you can literally throw a Meta Quest headset in a washing machine without having any noticeable damage 😂

Maybe the crazy shape of it required them to build a glass in two parts and then they used some sort of epoxy to put the two halves together and the epoxy is giving out

temperature changes and differential expansion? frame or glass warping? regards to design, yeah, there's probably an undiscovered stress point somewhere because of the shape and/or manufacturing process (reminds me of prince rupert's drops)

I guess that the crack has to do with the stress imposed on the headset while people tighten the grip against their face. Maybe this caused the headset to bend on either side against the vertical line between their forehead and their nose.

When things like this happen, it’s such huge news that I’m honestly dubious about the source.

Good for you guys, the video that other paid shill reviewers (like iJustine) will never put out there!

I think maybe because of the curve in the bottom, there is just more “glass” material there and when it gets heated, the lower part expands more than the rest of glass so the entire front glass will expand unevenly. Therefore crack starts

I've only had my Vision Pro for a few days and I have a feeling I'll be using it most days of the week. I've found it really nice to have my 3D printer status and video feed above the printer itself so I don't have to bend down and open the enclosure(it's placed on a fairly low Ikea lack table). I also used my quest 3 daily for doing homework or zoom calls(audio only)now that I've gone back to school and the AVP has made it much easier to multitask on this. I haven't really watched anything other than KZfaq on it so I'll probably watch a 3D movie later this week when I have free time to use it for playing around and not just productivity. I do wholeheartedly believe that this IS NOT for everyone quite yet, the price is one issue but I don't see it as the biggest one. Vision OS seems to be this devices biggest limitation while also being what makes it much better than the Quest 3. It feels limited in the ways that an iPad is. If it happens to work for you it'll be amazing, but if you have to try to make it work for your scenario, it's just not going to.

the new guy looks like marques brownlee at home

I feel like in 2024, it's refreshing to see something as straight as that break line.

Any spiegen case is the one you are looking for. Great quality, paid mine for s23+ 17 euros

Could the crack be produced by over-tightening the original strap while wearing the headset?

JerryRigEverything show how fragile those fake glass are.

lol marques just casually saying that he and his company no longer use 7k dollars worth of headsets for anything must be nice.

In the air, on a train, in a drawer, or at the store!

Not sure if Marques is out of touch on phone cases, or it's an iPhone thing... $15 is like the sweet spot for a simple black or solid color, rubber protective case that's fine to hold, good button feel, and won't degrade quickly. Got one right next to me that I used actively for two years, and has been on the phone through various use for another three. Ringke on an Xperia xz2.

Bet the crack is from the stress of the thing pushing on their face

Apple built a product no one wants or needs. Google Glass should have been a lesson

“Giant crack down the middle” 😂😂😂

Curved surface's is always more resistent than flat surfaces, what ever the material. If i were to guess, however, the crack is probably due to the dilation of the diferent materials. Glass dilates different then aluminum. Because of the inward design in the middle of the display, it probably creates more tension in that space.

Can't trust MKBHD due to his relationship with Apple. He's Apple's golden boy. Being mentioned in Apple's promotional event is Marques' wet dream, he would never do anything to jeopardize that.

Nobody care about this vr headset to be honest

A bent piece of glass in that way will be under incredible tension, while being incredible brittle. Then, some thermal difference can reasonably lead to cracking, because the stress has nowhere to go.

is the crack just the outside glass or the inside glass behind outside glass also?

People are probably putting it on and pressing each side equally hard to get a good seal and this creates pressure in the center part of the glass and you get an even crack.

I believe this crack is happening because of the stress you put on it when you tighten the strap with the side knob.. I haven’t had an issue yet, I use the other strap with the overhead strap..

I commented in a Reddit thread...if you read through the manual, theres some conflict... in one part it says it's OK to leave the battery cord connected to the headset when you're not using it. And another part, it says it generates heat and not to block the vents. And another part it says to make sure the unit is covered and protected basically when not in use. And other things like this that I saw. I don't think they realize that with the power cord connected, it does background activities, maybe like iCloud sync, etc. With the cover on its blocking the vents. so when you leave the battery cord hooked up to it and it's doing background events while you're not using it, and the covers on and the vents are choked… There's your heat buildup and your glass crack. ( I'm not even talking about the battery hooked to the headset AND charging the battery either... although if some people are doing that with a power brick inside the case, there's even more heat for you.)

Wonder if its cracking due to the increase in pressure when pressed against someone head and device bends/flexes when tightening it to get a snug fit.

Got to love the manufactured intrigue.

Every time a user straps on the headset if they are pulling the straps back or tightening ita bit much, that could cause stress on the front glass. Apple is probably bonding 2 pieces of glass together to get it to look like one seamless piece and the crack is happening at the joint point.

It's the same with every vr for most ppl you use it for a good while at the start and it ends up collecting dust after a while is what's stopping me from buying the quest 3 I hop into my 2 from time to time but mostly just sits around

Looks like it's probably not a single piece of glass, but two pieces fused together. Regular thermal expansion and compression might be stressing the joint where the pieces are fused, and causing it to fail, exposing where the two pieces were joined.

Still could be caused by heat, even if the crack stops from the bottom. Conside: cool air pulled in from the bottom keeps the bottom cool, while the to heats up and expands. That could cause the cooler glass on the bottom to crack. Temp differential.

I wonder if it would be the stress of the head strap pulling on both sides when it's on and then releasing when it's off. And that repeated tension stress and release may be it.

It's the heat from using the unit, the quest 2 gets hot at that spot also, so I think it's from getting hot in the case then cracking.

I have a pretty good guess what the issue is if anyone’s figured it out yet. My analogy I’m going to use. Regular scuba diving snorkel goggles. Every time you put those on and off your head, it flexes a little bit. It’s a lot easier to see. The outer layer is going to flex the most on the Apple vision pros and the stress of just people putting it on and taking it off a bunch of times put more and more stress on the center of the glass. Kind of like folding a piece of paper 1000 times eventually it will just fall apart in a perfectly straight line.

Also Aluminum is a huge heatsink and right next to the glass then setting it down how ever softly will always put some stress right where we are seeing the cracks. Glass was just a bad idea in this instance of material combination.

There's plastic on top of the glass, so they might as well have made it fully plastic and prevent the cracks or fully glass and prevent if from scratching at a level 3 with deeper grooves at level 4, which is 3 whole levels below glass out of a total of 10 levels.

I had long time ago a Puma sunglasses similar shaped and one long glass and it happens the same. So I guess is something quite common with the One glass lenses.

@Marques: As a black man, it’s really good to see that you’re hiring other skilled and capable brothers to work for and/or with you. Love it! 🤗

Any chance the crack is from over tightening the band for prolonged time? Or that plus heat? If the crack is at the nose bridge it could be from the slight pressure from your nose since we all have different noses. Maybe the cracked one comes from big noses?

When you have such a fold(don't compare it to a dome), it's a stress point

What about from people cinching the back strap on too tight putting tension on the frame/glass. Combine that with taking on and off just stresses the glass over time.

I have a narrow face and even on the quest i had to 3d print a custom face plate... so what i think is theres more pressure in the center, and for me i would tighten the strap a lot more when i had the default one. Considering its glass on aluminum, im sure the frame is bending to some peoples face when they tighten it... seems pretty obvious to me

I'd be surprised if this had anything to do with heat, first impressions is that this is because the glass is under tension when its on someones head, the straps pulling back at each side round your face will create tension across the surface of the glass and the indent for the nose will focus all the stress on that point. over time with the tension bein applied and releaved as it goes on and off someones head its really not surprising that it cracks.

Are they leaving it on while in the case? That might cause expansion leading to a crack

The samsung S10e (my work phone) had an issue where the cover on their cameras was too tight so temperature changes would result in the glass cracking. We watched my coworker's shatter while the phone was sitting on a desk. This seems like a housing tightness issue.

Curve = stress concentration which makes it fatigue faster. It might add to impact strength depending on the setup, but subtracts from fatigue strength all else equal

Could it be that the shape of someone's head puts some stress over the frame which in turn causes stress on the glass?

‘Your face is holding it wrong’ -Apple 😄😂

Looks like a temp or stress crack where the center moldings is.. The center is not as wide, so any stress gets put dead center .. This is a design issue with the shaping of the glass.

It’s got to be user applied mechanical force. I wonder if the frame support is distributing that force evenly. Like they built the flex in to allow for when people put it on their face, but they didn’t consider the inflexibility of the glass.

Jerry showed us that it's basically plastic. We hoped that it wouldn't just crack because of that but this is just weird.
