They (LTT) do tend to dumb down to cater for the general public but their move to having the lab and this purchase will also give the general public more in depth information which you can only find in enthusiast space. It’s still a win for us consumers regardless.

[@KL-tn1xc]

yes, but even then, if they don't do waterfall graphs i'm going to be malding. soooo. i guess i'm just setting myself up to mald. heh. even though crinacle says "waterfall doesn't matter" that's not entirely true when it comes to certain professional disciplines, sound design & mixing and mastering.

[@EliteSniperTV]

Their mainstream focus lets them do bigger stuff, I'm fine with it 🤷 I miss tf out of tek syndicate tho 😭

[@Vamp898]

It's not. It's a win for the KZbinrs and ChiFi Companies. Nothing of this is even remotely relevant for the consumer. Everyone who ever bought an Headphone/Earphone based on measurements and ended up with horrible sounding garbage knows exactly what I mean. Consumers have no advantage looking at measurements. Most of the best sounding Headphones measure horrible and a lot of painful bad mess measures excellent. For most people in this Hobbie it doesn't really matter because they don't really listen to music anyway. They buy their gear to listen to their gear but for the People who buy their gear to listen to music, measurements have pretty much no relevance.

[@CockatooDude]

@@EliteSniperTV You and me both dude, they had such a good dynamic and aesthetic. Ahead of their time really.

[@kornkernel2232]

​@@Vamp898 These measurements are the tool to help decided purchasing audio gear, especially with these consumer products where mostly unable to test out on the retail shops, only selected few but some just don't have at all and depends where you live. Not to mention, many of these products aren't even available on retail, so you can only buy them online. Not everybody has a friend who has a collection of audio gear for people to borrow. This gives consumer more informed decision than just being swayed from marketing speak. Which mostly aren't relevant anyways since it's easy to claim "balance sound" or "hifi quality". I find people actually looking for measurements are the one more likely care about the music, since they care about the fidelity they can get most out from their music collection, it even encourage them to actually acquire looseless and well mastered tracks to really enjoy the music from their better gear. Most who just buy headphones or IEMs are mostly end up crap ones, wasting money and time. This even limits their genre they can listen since many of the mainstream music will be tuned to at least sound okay with crappy audio devices. That's because they have more money for really master their tracks to work on those, but sometimes that may also limit the creativity on the instruments on the tracks due to having so many layers will easily get muddy tk bad headphones, IEMs or speakers.

[@JamieVatarga]

Also I'm pretty sure they're going to do sound demos anyway because well... dankpods

[@listener-reviews]

:yea:

[@whatr0]

i mean tbf, i think sound demos *can* be helpful as long as its made clear to take it with a pinch of salt and has a reference comparison. for the general viewer, it's a lot easier for them to be able to hear the comparison then just leaving them a graph overlaid onto the neutral target.

[@whatr0]

@Omega oh of course, but I think they're useful for helping a general audience better understand the tuning of a given headphone/IEM. like i said, it 100% needs to be made clear to take it with a heavy pinch of salt, but i dont think they're useless (especially if the tuning is particularly godawful in some aspect)

[@renniekimutai6293]

how u comment 21 hrs ago

[@sweetlows1]

He isn't the only one that does that too. i find it so misleading, the whole "hear the difference" thing, it is something Brian Tong does for instance. I think for the sake of comparison it isn't terrible for changes in frequency response between the two with the knowledge of what your own headphones sounds as a bias but that is about it. However LMG doesn't like to do gimmicky things for real reviews of a products. They may have fun with a gimmick of a product but they are very consumer first from what I can tell and Linus talks about transparency of reviews on The WAN Show often. At the very least if this does happen, like dankpods, they will explicitly say, this is not an accurate test and the factors that make that the case. I like dankpods because he listens to garbage headphones and having the HD six-hundos as reference just adds to the joke. Maybe Dankpods will make a guest appearance on LTT one day after making the jump to Floatplane after Twitch kept letting him down with lack of tech support.

[@toast1797]

From what I understand, the LTT Labs stuff is partly to do more detailed non-KZbin stuff, and also to do contract work (3rd party testing)

[@Hotrob_J]

Regardless, they dropped 50 grand, so they're not going to use it a couple times and let it gather dust lol

[@kornkernel2232]

Yeah, one thing with LTT that most people may not be aware of. They actually also open for business to do contract work for other companies. For example they sometimes do production for ads to some companies, considering they already have high end expensive gear that what you expect from a reputable media companies. They will really make use of it

[@benwu7980]

My understanding is there will be a more 'written' based leaning for the labs' output, whether forum based, or similar.

[@BubbaBearsFriend]

I really doubt that they'll do 3rd party "official" standards compliance type testing since that requires the lab to be certified. That requires a lot of effort, time, and money. I can see them offering services on a "as time permits" based on LMG needs first to floatplane creators though.

[@sinuslebastian6366]

Linus said that he's reluctant to go into 3rd party testing as it becomes a huge conflict for them to cover that product in the future.

[@noxalbus]

Well, they don't *have to* do sound demos from an audio perspective, absolutely. But for the average viewer who won't even spend 10 seconds learning about graphs, yeah they're going to have sound demos for sure.

[@FahmiZFX]

Undoubtedly. Also, it just make people think that they can hear the difference, thus more engagement points. Finna see that huge "Most Replayed" bump on that part real steep whenever a new video with audio demo gets released.

[@EricBentleyW]

What's the point though? By the time the viewer hears it through whatever random device they're playing the video on, and after compression, it's not going to sound like what the headphones actually sound like.

[@MrWizardjr9]

unless the viewer is listening to it through some perfectly neutral headphones or completely flat speakers it could be misleading though

[@Silicon_0014]

they'll definitely try to explain the graphs in a way people can understand (hopefully successfully). also there is no way the lab hires aren't aware of crinacle. i'm sure they'll relay what's important.

[@666dreamboat]

I think the most important thing for them to do is to always show the graph with like 3 pairs of headphones that people may have heard in that form factor: like apple buds, qc 35 ii, dt770, hd600. Most people get the graph but tell me it's useless without a reference point of something they understand. Then talk about non graph friendly things like detail retrieval so the listener can get a good idea. I'm actually not against doing recordings either, as long as they are shown with context to products people may have already heard.

[@dubi127]

exactly, for most users, graphs on their own are useless, for general public i think sound demos are more useful than graphs, but only in reference to other headphones, you dont get exact data, but you get a comparison, of course, distorted and mangled to fuck by youtube compression, but in my opinion sound demo like the ones DankPods does tells you more than a graph on its own
