I have seen many keyboards come across my table and this is the most beautiful I have seen this year. The Hope75S comes with an absolutely gorgeous Solid Brass weight that completes the look of the keyboard. The Hope75 also comes with both PE and EVA foams to help tailor the sound to your liking... so what sounds better?

Love how you go into the science of the sounds, something many of us find so important yet hard to understand.
Truly a hard concept even for me. Small metal box makes noise and it depends on so many different things :)
Now this is a good example where the high price reflects the great quality product. Loved the back to back sound tests, its a very useful, keep including this style. And as usual we got to learn something new and the why's about the foams, thank you
I think its all in that brass weight haha. That's where the money is going
I love how the sound comparison is short and consecutive! you can easily identify the difference
Yeah the only Eva kind of sounds like PE but it preserves some of the higher tones better
Seriously, you got me out here contemplating studying physics just so I can understand keyboard acoustics better LOL
Ahh, I heard what you did there; "Hope this comparison..." 😆Just wanted to give you credit for that.
And as always, another terrific and scientifically informed video. Love that you especially credited the source. Doing our community that unique trademark Keybored service!
Thank you for your continued support Marco! Glad at least one person gets my jokes lol
@@Keybored A thing I've been wondering -- is there much difference between the adhesive PE/EVA switch pads/tripods and the sheet foam of the same material? I will say that your comparison here matches what I've heard using the switch pads; but because they're adhesive to the PCB, I can't easily swap between the pads and a fuller sheet of foam.
My hypothesis is... no difference.
I looked to see a wink or something but it was more subtle than that ☺️
The sound profile reminds me of the Simpler60, a more budget friendly 60% keyboard which also has a layer of EVA foam over the PCB. The Hope75 is such a good looking board and I actually think that the price is fair for what you are getting.
wow! PE foam creates a V shape sound signature, no wonder it sounds "fun". The audio guys know what I mean 😜. Great video as always Scott!
Thank you!
Makes you smile… get it?
this got me hype for the Bubble75! Wish it had the light strip too though 😅
Thanks for providing so much information. You are my favorite reviewer because you try to explain sound profiles in depth
The bubble is a great sounding board! I'm sure it'll be fun to build also
@@Keybored its gonna be my first mech outside of of modding a few pre-builts! listening to this got me so excited.
First guy on YT to back these mods with scientific data. You sir, are a bonafide legend!
Thanks for taking such an in-depth look at this keyboard. I watched Alexotos's build stream of the Hope75X and thought the board seemed a bit meh, but seeing your build of the Hope75S in the various differerent configs makes the board seem much more promising. It'll be interesting to see how it stacks up against the Mode Sonnet.
Alex is a well respected builder so his content is top notch. What's interesting about this hope series is its dependence on the foam. Without it, it's pretty weak. With it however, it sounds pretty good. Take it for what it's worth! Some hate boards that depend on foam, others don't care as much so ymmv!
@@Keybored Yes, Alex's content is great and I'm definitely not trying to throw any shade. In a stream it's not going to be feasible to build the board in lots and lots of different configurations as you have in your RUclips video, hence the value of watching a few different reviews of any new keyboard.
Wonderful video as always! Really enjoyed the content. I use Poron switch pads from KPrepublic and I always wondered how EVA compares to it.
I tested with Poron vs. without. Poron basically makes the stock sound more pronounced and more crisp with GREAT bottom-out hand feel on the switch. It also gets rid of the dull/empty switch sounds and turns them into more crisp. I don't really know how to describe it any better.
The case looks absolutely amazing! Great vid as always scott!
Thank you potato! It was crazy when I first grabbed this thing out of the box... It was like a brick!
@@Keybored That flex when you didn't use any foam tho.. that was some crazy flex
Finally, the Tecsee Carrots are getting some love! I would love to hear your thoughts on Anubis switches!
I've finally found it! I've been looking for this keyboard once I saw the thumbnail few months ago! Very elegant looking keyboard.
THIS ! ! ! At last I can find the sound I've been looking for and it being explained to me ! !
people say the PE foam makes all boards sound the same but I dunno man.. it's still a little bit different to me and i LOVE the PE foam sound
I'm somewhat into both keyboard and audio hobbies. Funny how a lot of people (myself included) tend naturally prefer the V shaped tuning. In both hobbies.
Would love to see you compare both PE and EVA to poron under switches :)
Gorgeous keyboard. As always best keyboard content with a bit of sound science. Love this channel.
Thank you so much! Really happy to hear that
My GOD this board is gorgeous. I love the lesson you gave on sound frequencies regarding the PE versus the EVA foam. It makes me wonder what frequencies the IXPE foam does.
Anyways, you sold me on this. I preordered the Hope75 X Brass in White/Gold with the POM plate, though I'm wondering if I should get an FR4 plate. I kind of want a fuller sound, but if the FR4 plate has some flex cuts, I might get it. Just got to wait six more months... 😅
been enjoying your content a lot, always get to learn and understand something new about keyboards
Add a gold artisan esc just to top it off! It'll look sooo clean!
Sounds like a plan!
Once again an awesome scientific explanation. In layman's terms. Thank you so much.
You're very welcome! Thank you for watching and the comments!
This review sold this board on me for sure. The differences in foam's are unbelievable!
Finally, actual science and not guessing games. Love it!
Glad to hear it!
Thanks professor scott k, appreciate the way you make it easy to digest the information
Yet again, a very informative and interesting video! thank you!
how do you only have 60k subs deserves a million tbh
This is the best keyboard i have ever heard, great job!
wow the GB is open tomorrow, the kit looking good
now i know what keyboard im gonna buy next
Get the brass one!
This looks really cool!! Reminds me a lot of the Bubble 75 GB you convinced me to join :) (should be coming in a few months!!) Glad to see more premium 75% options! 75% > 65% for me! Thanks for the video Scott!
You know? This really is reminiscent of the bubble. The bubble is a nice sounding and feeling board also, and I do have it in my regular rotation!
@@Keybored This board is actually run by Velocifire, same guys who ran the Bubble75. They seem to create random studios for each and every one of their boards. Love the videos!
@@Keybored That’s great to know that even someone who has a lot of choice has it in their rotation! I’ve mostly used the more budget end boards (a couple bakanekos and Tofu60), really excited to try a more premium gasket mount!
Philippines represent!!!
You guys doing some good work out there!
Thank you good sir for putting so much science behind our keyboards. Much appreciated
Much appreciate your support and view!
Amazing vid! Will you also review sonnet anytime soon? I'm torn between Sonnet and this. I 100% love the look of this board over Sonnet. Do you think Alu plate will bring the sound even louder and less like other PE foam boards?
I haven't had a chance to review any of the mode boards unfortunately :( but alu plates will create a clackier sound VS pc
I'm gonna be honest, I had a hard time finding a difference between those PE foam and EVA foam clips!
amazing vid as always :)
You covered in your Keychron Q2 video that you used a paper towel instead of PE foam, and I assume that this absorbs and reflects different frequencies than PE foam. Any thoughts on what kind? I would assume it absorbs less.
Love these science segments, please keep them going!
Yup! I'm sure the paper towel is similar in concept as the PE and Eva foams. I haven't done a 1 to 1 comparison but perhaps I can look into it in the future!
This Hope75 looks llike combining Mammonth 75 and Jelly Epoch. Look nice and sounds thoccky! BTW will you consider live release with chat room?
So many great boards coming out these days! I did miss the mammoth but that thing looked pretty nice also. I have been considering the live releases in the future! Should be fun to interact with you guys at release!
Instead of "look at all those chickens"... Look at all those flex cuts xD. Great video and solid build as usual!
Haha thanks!
That polished brass weight i stunning!
It looks and feels like a gold bar
I'm getting this board I love my gmmk pro and I have a zoom 65 on the way but this looks to be that premium board that I've been wanting.
As usual you never disappoint andddd another kb I cannot afford
wow that thing looks beautiful
I love how this thing looks! That gold bling!
Interesting, when I removed pefoam from Owlab's keyboards, I experienced a decrease in sound completeness, and it was easy to understand because there was scientific evidence.
The PE foams seems to put a "V" equalizer on the boards! It's very interesting!
Such a beautiful board, only thing that has me thinking is weather i order it like yours or white top / black bottom with silver brass.... decision.
The sound is crazy in any configuration
Man, that board is GORGEOUS. I feel like they tried a little too hard to design around the thin flex cut PCB and the flex cut PC plate. I wonder if they would have been better off using a thicker PBC and regular plate.
I think the thin pcb does add an interesting sound, but I do agree, prob didn't need as much flex... It was airing on too much
@@Keybored erring* :)
Another banger video! Was always wondering how the eva foam affected a board.
It does a pretty good job!
Thanks again for the science!!
I liked the EVA sound.
Thank you! Glad the science is helpful!
you should do a foam comparison video just build the same keeb with a bunch of diff foams
It looks so sleek. But tbh, it also shines so well with the glacier
They're like partners now
That scientific article was super helpful. Thanks!
I love eva foam, so easy to wrok with, you can do so much with it, I'd reccomend trying to do eva foam "gummy mounts"
Thanks for review Scott, top notch quality as always! How you compare typing experience and sound of Hope75 to Buble75?
Hope sounds more dense than the bubble and it's a whole lot heavier. Without the foam the hope is also much more flexible
I definitely like the S better than the X as well after taking a look. 5 more days for this GB and I don't think I'll be able to make it. I'm missing the AV4 as well. Just had too many expenses and bills to take care of and my deposits are all late. Hahah. Even trying to sell my S22 Ultra just to buy keyboards but I don't want to take too much of a loss.
I'm looking forward to the content about building your own custom keyboard from scatch by PCBway
I want to see sci-boi Mark-1 keyboard 🤣🤣🤣
glad i found you dope video sick board.
You are what I image carykh will be like when he grows up
It's kind of like a hifi speaker analogy. You perhaps want your keyboard to produce a flat response on the full spectrum of frequencies. If you prefer a heavy midrange, go with this type of speaker. Otherwise tune your keyboard to have equal treble, mids, and bass
I ordered an EVA foam for my keyboard after watching this video, thank you! Now, poron switch pads or not? So confused..
great vid! this sounds just like my mammoth 75 so I may have to pass on this one unless i want a different colorway. The Mode Sonnet looks promising as well
Sonnet does look promising!
Agree, all 3 different configurations sound really nice however PE foam is slightly better than others for my ears. Thanks for you video, its not the most beautiful keyboard i ever seen (my Dream keyboard is SEN80 by IQuinix - btw SEN in my polish language means DREAM!), however it is beautiful indeed.
had to buy this.. so good looking.
Looks beautiful and sounds like an epoch
dope video! just wondering where you got your all black cable, thanks 👊.
Cable mod!
That civic reference tho. Type R owner here ;)
That looks amazing! Better if its in my hands
Haha it's so heavy in the hands
Video suggestion: suggested keebs for each price point for a 75%.
Wouuuh the sound is amazing where i can bye ?
You should try reviewing the anubis vs boba switch!
I wish you'd actually post a sample of without the case foam! Realistically that's what I would want to run (only the very thin bottom most layer of foam). Using the EVA foam sheet with that might offset the thinness too.
I recorded it and thought man that's just meh lol
@@Keybored Right, but we should know what it sounds like, useful information, especially in comparison to the other sound test you showed.
Awesome video! How was the coating finish on the board? Is it rough or on the smoother side?
It's actually very smooth. Didn't do any scratch testing or anything but it's on the smoother side
@@Keybored Thank you!
Wow perfect sounds I want this board wish it was 65 percent t though and jt is kinda expensive and tired if long as gb
Philippines Keeb content creator represent!
Yall doing some good things out there!
Would u say this is the best keyboard uve reviewed between the 400 - 500 dollar price range in stock ? Im looking to get this for my first custom board it looks really premium
I would say the brass version is one of the best looking in this range, but structural design and assembly wise, I feel there are other options that will best this in this range.
hello dear Keybored. Can you advice or recommend to buy ready 100% Fully sized keyboard, with some light switches ~45gr force which will cost around ~100$. Currently using Cherry MX-Board 3.0., wanted to buy keyboard with some similar keys... Don't like when keys or keyboard it too tall
For that prize I hope it comes preinstalled too😉
What would you say is the sound characteristics of kitchen towel? Saw it in your keychron q2 build.
You make good stuff
does thicker PE foam contribute to a more marble-y sound compare to a thinner PE foam? 0.5mm vs 1mm?
By any chance, can you drop a tutorial video on how to paint a metal keyboard case? TIA!
Hmm that is something I do not know haha. I might have to ask Betty
Hey scott, I was just wondering could you make the scientific part dark mode friendly?
Can u make a sound test on a same keyboard between the gateron box black ink v2 and jwick black linear switch? Idk what to choose between those 2
Overall, how do you think this keyboard compares to the Bubble75? It seems super similar except for the weight/led and the thinner PCB. They both have EVA/IXPE foam options too!
It's similar in design but how the case comes together is different. And the weight below for the hope takes away some interior volume so the sound is different as well. The hope sounds denser and bubble sounds more aerie
@@Keybored Thanks!
still can't say for sure which one I like more since they all sound nice...
All 3 actually does sound good!
great vid once again KD! but but can you get a new wrist rest? :D :D :D peace
Hahaha yeah I've been using the same one all the time. I need something more comfortable
i don't understand that "flair" led.
it's on the back... where you'll never look at while it's on your desk.
How do you think these kinds of foam compared to the silicone dampener?
Wow the explanation is super interesting! I wonder if you could record the stock sound of a keyboard, fft it, use the data from that study to do a weighted filter based on frequency, then the sound you fft back would reproduce that 'marble' pop we hear irl.
That would be an interesting experiment!
So PE foam will scoop the mid frequency. Nice finding
Hi, i don't mean to be a buzzkill but the polyethylene foam from the research paper was 1-2 inches or 25.4-50.8 mm thick.
As you mentioned in another comment's replies, the pe foam in the board was (you assume) 0.2mm thick or roughly 127x thinner than the thinnest foam used in the paper. I'm not an expert but I'm pretty sure thats over-extrapolating the data a fair bit. Maybe the data still holds up at that scale but I would honestly doubt that. I hope you see this comment so you can address this issue in some way, even if to retort it. Thanks! :)
@8:04 I see screws in the PCB, are those for standoffs for the PCB/Plate?
Where can I buy appropriate PE and EVA foams for keyboards so I can do actual CUSTOM work?
I don’t think this keyboard really can compare to the 7v apart from the aesthetics. 7v can be used plateless, is a leaf spring mount, and most importantly, DOESN’T NEED FOAM. Still the 7v is one of my favorite boards in my collection even after owning boards such as the Mr Suit, Vega, and F1-8x.
Yup looks like the 7V
Does this board have another group buy? I’m planning on buying these.
I’m waiting for delivery of the X with an FR4 plate
I’m still going to use it with no PE foam and no plate foam as IMO is cheapen’s the sound a bit.
I’m planning to use Just the case foam and I bought some UHMW tape to tape up all the flex cuts in both the PCB and plate
HOPEfully it works 😂 and I get some clack out of it
Hey, how are you enjoying your Hope75X? Any problems with the strength of the magnetic feet? I also heard about an issue with some of the screws of the top case interfering with some switches. Did you also run into that?
@@ac_4466 I never got it in the end.
A lot of them came through with very bad QC.
A large percentage of them had no inside bevels at all and Velocifier just sent them through anyway!!
I will never trust that company again!
It’s clear that they are just pumping out model after model with only profit in mind.
Luckily my vendor was gracious enough to warn me and ask me if I wanted a refund before they sent it out which I gladly took and bought a TGR Tomo from the same vendor instead which I’m very happy with
In my opinion it's just
PE=marbly
EVA=creamy
Really needed this comment. I’m waiting for my board to arrive and the last decision I needed to make for my build was pe or Eva and you just said what I wanted to hear
So many boards named after positives 🤷♂️ I need boards named like Despair75, Depression65 or EmotionalDamageTKL to balance it all out
Lol goingbroke75 also sounds like a good one
I wonder what type of material(eva, poron, silicone) the plate foam hope75 is using. 🤔
Plate foam feels soft like poron
@@Keybored Thanks Scot
