Thank you so much for the video, and the measurements. I have my hd 25 lights coming in this week, and I only ordered them for this mod. Been wanting to do it for a few months now and recently found a good deal on a used pair. I will be trying some black HD410 and yellow HD414 foam pads on them (if they fit). I really like the look of vintage sennheiser headphones (like HD410SL), so I’m hoping this works out. Would be cool to get some measurements with foam pads too. Thanks!
Looking at the graph, it reminded me of my 3 pieces closed back guitar amp cabinet response when I leave it open: relaxed mids and highs. What surprised me was that the graph reading with the velours pads showed even more bass information than the original with the earcups in, as well as bringing back some of the mid content. Willing to see you checking those beyer dinamics pads video. Let´s call it Frankennheiser HD25 XD Good job!
The graphs are normalised at 300HZ - we actually had to turn up the volume a bit to get it to match the volume of leather pads... SO... the bass probably stayed the same and everything else dropped
this is so cool happened across yr channel looking into beyerdynamics recommended by a friend but i’m rly looking for a cheap ish flattish decentish-sounding, VERY OPEN headphone and this might be what i wind up doing i wanna wear them while i’m on calls on my pc and still be able to hear the room around me (it’s a private room so i don’t have to worry abt sound bleed from my headphones into the room either so open back is ideal)
Would definitely be really interested in those over-ear pad adapters, I would certainly want to experiment open-back with a set myself. I don’t know why this hasn’t been a thing before! Very curious.
Very cool and geeky video. Again - compensation on the target curve you have in your software makes frequency response looking a bit misleading. For instance, it looks as there is a severe bass roll-off, which is not the case in reality of course.
I don't know... if you look up HD25 frequency plots most seem to start to roll off under 100hz but the scale on the graph used does not start at zero db so it makes the dips and peaks look more pronounced
@@CustomCans Sure it's great to see that graph doesn't start from zero! I meant that your software contains some kind of target curve and the measurement we see is not a raw measurement, but the one that's compensated accordingly to that target. I understand that your goal is to see the change in sound, not to perform a precise measurement. And this stand is not targeted to make precise measurements, which is fine. But not seeing nor target curve to which measurement was compensated, not an initial raw measurement doesn't make things easier ). Take a look at the data on the graphs through the link below - there are both raw and target measurements presented, which is giving a picture of frequency response, that's much closer to what you really hear and that's easy to read. crinacle.com/graphs/headphones/sennheiser-hd25/
That is a fare point and frequency plots don't really help show how they sound under normal use. I know things like waterfall charts and things give a bit more of a feel for how they respond but don't look good on screen. I will try to upload the raw data for people to download and play with in future
I have not checked out the 250bt yet but do plan on getting some in at some point. HD25 drivers would be tricky to fit in some grados - HD280 drivers would probably be a better fit but I have no idea how it would sound

This is awesome - a different mod to smooth that treble peak! Thanks for more sweet content👌🏻Tempted to get a second, used pair to experiment... 🤔

If I get round to doing an update on these U will include those measurements

Brilliant! Looking forward for more videos of this kind. Thanks!
Awesome, thank you!
You could use that shiny new 3D printer to make your adapters :)
Yes - we probably will ;)
this is so cool
happened across yr channel looking into beyerdynamics recommended by a friend
but i’m rly looking for a cheap ish flattish decentish-sounding, VERY OPEN headphone
and this might be what i wind up doing
i wanna wear them while i’m on calls on my pc and still be able to hear the room around me (it’s a private room so i don’t have to worry abt sound bleed from my headphones into the room either so open back is ideal)
anyway thanks for sharing the vid !
subbed and gonna watch a few more haha

Our 3D printer has been tied up for the past few weeks with other projects but I will get round to designing them soon
I second this! Definitely interested
@CustomCans were the larger adapters ever produced?
thank you for your videos!, great job! golden hands!
Glad you like them!
Nice

wondering what the 25 drivers would be like in a set of grados ? what drivers did they put in the HD250bt ?
I have not checked out the 250bt yet but do plan on getting some in at some point. HD25 drivers would be tricky to fit in some grados - HD280 drivers would probably be a better fit but I have no idea how it would sound
I have a similar looking pair of headphones from Sennheiser called the HD414SL. Nothing new under the sun.
The 414 are the HD25's great great grandfather ;)
@@CustomCans HD414 SL only. It is different from HD414.
Perhaps a different cable could provide the last little bit?
Yes - in the next video we will try that
Is there any chance you will do a sony cd900st detach mod? Also good content. I found you when i was looking a dt990 detach mod.
As you can see, we are a bit booked up with jobs at the moment but if you have a pair you would like to send in to have done we could do it mid July
looks promesing. The open cups are 3D printed?
No - They are the standard parts, I just removed the outer shell from the driver
have you got a few different braiding patterns for cables? be a good vid i reckon.
There are a lot of videos on braiding paracord - we really only use a flat braid pattern
Guten Morgen Jason! Wooden sennheiser/beyerdynamic earcups, is it something you want to try? :D
I would like to try it but my Lathe skills probably are not up to it and CNCing is expensive
