[@bobbyhutter5654]

god DAMN IT do i ever regret getting into this hobby - i remember when i could make decisions. those were good times. However, because of your hard work and thorough documentation of these varying materials - i can now confidently say FR4 is my favorite; something i wasn't able to say before I had watched. im very appreciative of your scientific approach and i thank you for having done all this hard work for all of us.

[@justinhille8151]

This is so impressive! I haven't been able to find such well-thought-out comparison videos anywhere else!

[@JL-fh4qw]

Brass seems to boost both low and high end simultaneously, FR4 is similar but less high end and more midrange. POM and Polycarbonate are very similar, not much midrange or top end, maybe low midrange and lower end but at the same time you can't say it's thockier than FR4, a lil more muted. Aluminium has a little scratchiness to it despite it also adding some low midrange, which makes me think it boosts a bit of some very high frequencies above brass even though it's not a clacky sound.

[@raymondmichalak1026]

Personally I don’t like how brass feels it’s too stiff. I don’t think high end is the right word to describe it. It’s just different.

I absolutely hate brass in person it's much worse then this video. Pom has the most pop in person. Pc is right there with it and alu is great with Mx blacks or op blacks on this board. Brass is the worse out of the bunch tbh. But then again it's all preference tbh it would of helped if he actually did good with luring the stabs and switches he had so little pop compared to what there should of been and pc/pom with switches that sound unused sound worse when lubed though sound way way better if they were all lubed correctly these plates would of sounded much different I am not trying to be rude but it was horrible lol

[@neiylaQQ]

From the bottom of my heart I appreciate your honesty of not being able to tell exactly which plate is which by sound. I was starting to think that there was something wrong with me :D

[@hardlinenexus]

Oh trust me, majority of the world can't... At least not without a decent amount of time spent training your ears by watching and listening to a bunch of sound tests or trying by first hand experience lol.

[@bodabodaguy3193]

hey man thanks for this! I'm loving the fr4, I'm actually back into this hobby, got some bubba u4t silent tactile switches like nearly 3 years ago, and finally I decided to make a new build. so this vid has helped me a lot! cheers!

[@JustinHernandezkhz]

Nice! Appreciate you doing the hard work and documenting it in high quality. I just put the FR4 plate and V3 Everglide Water Kings in my Eighty and I’m pretty happy, it feels and sounds the best to me. Switched from the aluminum plate with Signals.

[@hardlinenexus]

I heard good stuff about Everglides. Which ones you recommend? Do they have more than one type of switch?

[@fragile784]

best plate comp vid i’ve watched. learned a ton

[@mrjohnjones]

These are great comparisons. I appreciate them a lot. If you'd do a sound test similar to this in the future, I would suggest using a metronome to match the speed you're pressing the buttons across different video cuts.

[@hardlinenexus]

I've realized that lately, I need to match my patterns

[@jdbaker82]

These videos were amazing thank you I feel the same way!

[@Indra_Ninja]

Brass has always been my go to but interested to try FR4. It sounds thockier in your sound test!

[@hardlinenexus]

It is thockier

[@mrperlai]

Great video! Thanks for putting in the work. I'm like you, more able to distinguish by feel than sound. I spent too much time at concerts I guess (but will end up saving hundreds of dollars on audiophile equipment). Maybe with time I'll begin to pick up on the nuanced differences. As for feel, I've yet to try FR4 or POM (though I have both on the way). So far I don't dislike PC's relative flex. It's an interesting experience using really tactile switches on it (Holy Bobas). Maybe I'll like PC less with linears. Anyway, like you, still a lot of experimentation to be done. Cheers!

[@Rhoadspc]

Insane amount of behind the scenes on both parts of these comparisons, but it’s valuable to anyone watching. I gotta say Brass and Aluminum take it for me with both types of switches

[@hardlinenexus]

Ill be doing a new plates comparison video with Mode's new 65% keyboard soon. Will include carbon fiber and copper plates

[@Arguing101]

Awesome video. Straight to the point, great methodology, and not afraid to diverge from the mass opinion of how plates make a drastic sound difference. Also cool to see someone have the same unorthodox right hand typing style. IDK when but I stopped using my thumbs for spacebar and shifted to using my index finger

[@hardlinenexus]

Someone pointed out my typing style and I've been trying to correct it. I know it's not proper, but after a few months of trying to type "properly", I'm done. I been typing with index hitting space since forever... habit is burnt in lolol

[@Arguing101]

@@hardlinenexus ironically I'm pretty sure I started hitting space with index finger after spending a week trying to change to correct home row. It just feels more ergonomic having my hand angled I will say my WPM went from 110 to 130 when i started doing index finger space bar 😂

Thanks man, these are awesome videos and I appreciate the effort that went into this. Personally I like Alu a lot and FR4 is great too - the others don't really add much for me but Brass is kinda unique and sometimes you just want that slap, know what I'm sayin'? :D

[@robsinHL]

Ironically carbon fiber is my favorite. One for my dz60 from kbd fans and one for my preonic, a PLA / carbon fiber blend that I printed. Stiff but not harsh sounding. Sounds great in aluminum cases.

[@davieslm]

Great video and it was very useful in helping me to pick a plate. When the Mode Eighty becomes available to order this month then I am going for all Black with Boba U4T and GMK Wob switches and the FR4 plate. Have you preordered the Mode SixtyFive? If so when what colourway did you pick? Andy Nguyen did some tests with the Mode SixtyFive and brass bottom with tactile switches. The cheaper aluminium bottom sounded much nicer. Does the same apply for the Mode Eighty? I.e. stick with the stock aluminium bottom.

[@hardlinenexus]

I did order the 65. I'm also working with Mode to make some videos for them, one of the videos being a plate comparison like I did here. The main reason why I'm redoing the plate comparison in 65 is to incorporate two plates that weren't available for the 80 back when this was uploaded (copper and carbon fiber). I'll be getting my samples and the 65 this month (in a couple weeks). Stay tuned :)

[@davieslm]

@@hardlinenexus Great! Look forward to your video.

[@sprazer]

When you say the POM is too soft, can you elaborate how you not enjoying it? I just bought the Keychron V1 and then I just learned about the gasket mount and I am thinking about investing money on modifying the board to be gasket like (cutting the standoffs and such) The thing is I have never tried a gasket keyboard and I don't have access to try it out in where I live and I am not sure if I will really like super soft feeling....

[@hardlinenexus]

So plates like POM and PC are softer than the other materials. This video is a bit old and I will say my preferences have changed a bit and I can appreciate POM and PC plates more now, but they still aren't my main preference. To elaborate, I think at the time of doing this video, I just didn't like the installation process of POM and PC plates, switches take a bit more work to fully seat into the plate/PCB stack is all.

[@bernreccion]

Hi! My current keeb has a steel plate(stock) and I'm rocking u4ts in it. I have an option to upgrade my plate to a POM plate only. Would it make a difference in terms of sound and feel? I'm fairly new in the keyboard world. Btw nice comparisons!

[@hardlinenexus]

Yes, steel and POM are basically on the complete opposite ends of the spectrum for both sound and feel. POM is very soft and firm for typing. Steel is solid and can sound high pitched in comparison.

[@muCephei_]

I actually like Aluminum sound the most

[@caseykukielski2410]

I currently have a hotswap PCB with FR4 and POM plates. The FR4 is less flexy but to me it feels a little softer and has a better sound profile. I think I'm gonna order a solder PCB and POM or FR4 half plate for more flex. You still think FR4 would be the best half plate option?

[@n3lls81]

Thanks for the video, yeah tactile makes the plates sound a bit similar. I prefer brass for sound and feel but then the sound difference for me is minute when I am actually typing normally and not spamming like in youtube sound tests videos.

[@ChickenMcNublets]

Now i'm questioning whether or not i'll prefer the softer typing feel of PC... Guess there's only one way to find out lol. Still really want to try FR4 though.

[@hardlinenexus]

There's no right or wrong. You can always just get the one you want and can always get the other later. Experience is good

[@kennethfajardo3604]

Hii, did the tactility feel less when you go for a softer plate compared to a stiffer one?

[@muhammadali-io8hl]

I hope you or anyone could reply, im actually using a keyboard with full plastic build and im hoping to switch the pcb plate if i switch it with aluminium would it be safe ? And what would be better aluminium or acrylic (plexi glass or what ever people call it) the keys are black optical.

When I built my mode with alum vs FR4 it sounded totally different

What did it sound like to you? The differences that is

[@tombaker2510]

@@hardlinenexus The alum plate was definitely a higher pitched sound comapred to the fr4, FR4 is definitely the more thockier sound. I understand you might not like the soft typing feel of the pom and poly but they really do sound different even in your sound test.

[@vaxtrixradicalbro4295]

How did you get any other material for the plate besides alu? I checked mode's website and I couldn't find it. Is this something you got that was made by another creator or was this some sort of group buy for the Eighty that I might have missed? EDIT: Nevermind, I've found it but I'm disappointed to find that these other material options are only available for the solderable plate. I plan to get a hotswap pcb but now knowing this I'm not so sure anymore. Do you think that the solder plates will work on a hotswap pcb?

You are correct, the plates are for the solderable PCB. But I used these with the hotswap as well and they are compatible

why would you use such a quiet board to compare sounds

[@hardlinenexus]

"such a quiet board" is subjective. Mode Eighty is also the only custom keyboard I personally own that has this many plate variations. And it's also a board that was more accessible to the public with a fast delivery time. EDIT: Also, it wouldn't have really mattered if I used some other boards, because each one will sound different regardless. If I did one with a Keycult, RAMA, NK65, Tofu... whatever, people are going to ask for comparison in another board. So I used what I have.
