New Beyerdynaimc DT770 upgrade - the V3 custom cans mass loading and damping kit

k so how many people rushed to the emergency after trying to open the cans with a set of scissors?

In shortcut - This mod is making 30ohm sound profile from 80ohm version

I hate to say it but I am disappointed with this mod. I did installing/removing V3 kit three times to make sure there was no mistake. Final effect was nothing like sound comparison between standard 770 and v3 770 presented on this video. I am aware of the fact that mini dsp is not perfect sound measurement device but gives some image of a expected result. In my case v3 mode made my 770 sound a bit worst. Low bass didn't improved at all, opposite, I've noticed less oompf in low frequencies, below 60Hz. Not much of a disaster but not an improvement either.
Also V3 was supposed to add some low mids and tame Beyer 9kHz peak - non of those sound upgrades were present on my headphones after mod... and I rather have pretty solid ear.
I decided to remove all foam and leave rings as they didn't affected a sound in a bad way, I am not sure if they improved anything but generally increasing weight of a driver's chassis is a good thing.
My disappointment is deepen by the fact that cost of this kit including all import charges, shipping fees outside UK came up to near 25% of a new DT770 value.
Anyway, if you find this mod an upgrade - good for you. Nothing wrong in a DIY hi-fi hobby:)

Does this mean it will become better for the Mix?
Another question: Can I order the headphone without a cable?
One last question, can I request a special design for the dt 770?

Is there a place I can get that white cotton ring that comes with them stock I lost one of mine

cool mod :)

Is this compatible with the DT770 pro x ? If not, are you planning on releasing similar stuff for it?

Hola amigo, compré unos Dt 770 pro de 80 Ohm y los estoy usando con una Audient ID14 MkII. Mis audífonos distorsionan en los graves cerca del punto dulce de escucha, podrías ayudarme?? Los destapé con cuidado, no les vi pelos, están nuevos. :(

The V3 mod is great, soundstage is more apparent, gives a tidier low end, and the top end is tamed really well while keeping the clarity.

However, for those of you with thumbs for fingers like me, and/or have a set of older DT-770’s, it might be worth buying a pair of new pads as I ripped apart the inside join all the way around, doh!

Hi! There is no mention of the bass port, which is tuned in V2. Is it because with the foam the bass port does not do as much anymore?

hello, i love the dt 770 soundstage, does the v3 mod sacrifices some soundstage?

I have the Uber 770 80ohm V3 from you guys, just ordered the V2 kit because I want to experiment. Wild question - what happens if you have both kits installed at the same time? Have you guys tried that out?

Excellent overview sir. Thankyou. V3 ordered. I use mine with my Roland TD30 electronic drum kit, so hoping there's a slight improvement in the bottom end.

i had DT770 250ohms and loved the wideness and the sound-stage but due to my tinnitus and sound sensitivity i found it too bright and sold it. i switched to the akg k371 but i find the sound stage on these very compact and very narrow sounding (although less ear fatigue) im thinking about getting the dt770 again (the modded one from your shop) i just cant find any headphones in the same price range with the comparability and build quality,ease of repair as the dt770's

Thank you very much for the Video! Just watched it and talked to my Father in law who recently bought the 990 Pros. I got myself the 770 Pros 10 years ago. We were so amazed that we both ordered the V3 Kit for our headphones straight away!
Really excited how it sounds in person!

Ive recently installed the mass/damping kit and balance upgrade into my dt770 250 ohm. Really does elevate them to a level where you realistically, need nothing more expensive.

Got a question, will the V3 version work with the detachable cable mod as well? Or is it one or the other, I just got a set of dt 770s and I was going to order your kit to DIY my headset.

I was looking to get a pair of the v3s and i was wondering if there is any way to compare them to the letshouer S12 iem as that is what i am used to using these would be my first good over ear closed backs

After unsuccessful attempts to listen and produce amateur music using Brainwawz HM5, Yamaha HPH-MT5, and wireless B&W PX headphones (wired), I decided to purchase Beyerdynamic DT770 PRO 32ohm. They suited me best in terms of construction, comfort and interesting sound, but for me they were too sharp at the top and quite tiring in the low tones.
I had seen customcans kits before and decided to give them a try. I decided on the V3 variant but with the whole set including the central key-shaped plug, for me without this plug the high tones were still too irritating, although everything else was great, this plug has the impression that it takes up a bit of space, but in the end I like the way they present the music now.
I recently had the opportunity to listen to the DT880 and I have the impression that the closed DT770 32ohm after the v3 mod now sound very similar to the dt880 250ohm, although the treble in the dt880 is a bit sharper, perhaps more clear or detailed,
I don't know if it's also a matter of resistance 32 vs 250 ohm. I use velor pads (although the set included eco-leather pads) - if I want a bit better bass response, I use eco-leather. Thanks to the V3 mod, I can now wear these headphones all day long and they don't tire me out. Well done.

Hey, i’m trying to decide between the V2 and V3. I want the bass to be able to go deep, but I don’t want it to take away from the other details in the music, what do you suggest?

great mod this, fitted mine yesterday.
will be using the 770 much more regularly now.
had to swap out stock pads though as they clash with my glasses and make horrid creaking noise whenever i move. fitted some dekoni hybrids which dont suffer the same issue. has altered the signature slightly ie reduced the bass, but not by much.
i am tempted by your modded DT1770 now that this has whetted my appetite.

I'm sitting here watching this while wearing my stock DT 770s. The audio tutorial does sound much more different than listening to the song directly. I do understand that previewing the music via the binaural microphones will have different results. The previews have a much more crisp tone (which I don't personally like), while the actual audio from the song is more warm. I'm sure the V3 bass boost benefits a ton from these mods. Planning on doing the detachable cable mod and getting the foam inserts with weights

Also on a side note, I've noted a crackle from time to time with my DT 770s when there is a ton of boost. Would these dampening mods help reduce those effects? Thanks

I just bought the V3 kit for my DT770 PRO 80 Ohms. Thank you.

Sorry to take it off-topic, but the way the ear-cups are designed to move angle is very poorly designed, and results in a huge CLUNK sound sometimes. I haven't found anyone else who finds this, nor have a solution. This is my third pair...

Hi there, this was an awesome video. Wondering if you have any recommendations for fitting a microphone into the headset. I understand I can probably just get a BT accessory and attach it but if I'm going to have the cans taken apart anyways...

I was able to get a used pair of DT 770 pro's (250ohm) for only 45 euro!! It arrived today and I'm very happy with the quality and comfort, but the treble is a bit much to my ears. I might pick up this kit, seems like a good deal 👌

hi, will those mod sets change the character of the different impedance versions of the DT770 in the same way? I plan to buy the 32 Ohm version to run it on my work PC and my phone.

I know I'm late to the party, but just incase you didn't regift the ones that someone else threw back into the give a way....

On a serious note I just purchased the DT 770 Pro 250 Ohm about a month ago. They are my first headphones that I bought without testing that I loved at first listen. I tried AHG sheepskin pads, but they made the sound to dark. I then bought the Dekoni Choice leathers based off of Z's reviews, they were better, but they still kinda killed that Beyerdynamic shimmer that I love in the DT 770's.

I am leading to a question... I promise.

My pursuit lead me to you all, and I cant thank you enough for your videos, and all the info you share. Your sense of humor really adds to the videos. I wish I seen your pad rolling video before I tried the Dekoni's. You were right on... sorry Z.

Which mod do you feel keeps more of that Beyerdynamic sizzle in the treble. My goal is to enhance the bass with detailed bass, hopefully a little more punch, but not at the cost of the mids or signature treble.

Thanks for any input.

Has anyone removed the felt ring with this mod to tell how is the bass? :D

Got my kit from last week, going to install it tomorrow ! Pretty quick from UK to East coast USA .. Along with the demo that showed us the differences, thank you for the tutorial ! Hoping it works as well on the 250 ohm model I have.

In your opinion how does the DT770 80 ohm V3 compare to the DT 700 pro x?

V3 installed (without the central 'keyhole' plugs), so far so good. The immediate impression was of a reduction in bass, but it's quite possibly due to a lift in the midrange you mention, which of course is the range we're most sensitive to, hence subjectively louder overall. But definitely tighter, less boomy bass. A test recording I use is an all-analogue one by Simon Phillips, very bass-heavy mix (his kick-drum and floor toms, and Anthony Jackson's six-string 'contrabass' with Jackson spending a lot of time on the bottom B-string) which tended to get out of hand with the bit of bass-boost EQ I generally use, and it's definitely improved.

That's a very nice mod. It seems like there is still a treble peak, so are you interested in building a filter like dt1990 on these?

Just picked up a second hand pair of DT770 to balance mod. Would be interested in the V3 foam mod. Fact for your son - Owls cannot move their eyeballs, they move their head to look around. That's why they can twist their necks almost 360 degrees.

I recently bought some new pads, a headrest and a v2 kit from you, seems like I should've waited just a bit longer, now I want to upgrade to the v3 already haha.
For an incredible fact, did you know snails have 13.000 teeth?

Just installed the mod. Works great on my DT770 80ohm all black edition! The bass is quite heavy but controlled. Headphone feels more mature with this mod.

Great kit and good price too, good job! I find installing the middle foam insert with the keyhole shape out makes the position over my ears super critical. It's as if it emphasises phasing a lot. I have a TC Electronic Clarity, so I can obsessively watch a correlation meter while listening. Even with the meter hard right, position on the head is sensitive. Weirdly, the bass (for me anyway) feels recessed. So I tried again with the middle foam insert removed and bingo! Nice. Ring weight and outer foam FTW. £15? Excellent!

I'm curious about how the extra foam inside the cup produce this result. Like what's the since or train of thought behind it.

Interesting..Ive owened the original 600 ohm 770's from 1980's/90's? and have always been more impressed with them. More linear and clean than modern DT 770's Looks like you might have managed to reverse engineer the sound signature to the 'better' sounding original !! :)

Why the big paws ?

Here is a joke for your son - how does the ocean say Hi? It waves.😂

On to the video.
Nice, this arrived just in time when I started experimenting with bigger pads on my 770 80 ohm, in which I have a v1 kit for damping them.
Would you recommend removing the dynamat which came in the v1 kit (which is glued on the back of the cups) before installing the v3 kit?
And also, did you try to measure the headphones without the cotton ring which sits on the plastic inner ring, would that have some impact on the sound with the new v3 kit?

This will add more options for further modding my headphones 😅

Cool fact : my pair of DT770s is 5 years older than your son 😊

I would love to upgrade my v2 to v3. My amazing fact, there is more water/ocean under the earths surface than there is on top :)

Fantastic!
I have the V2 mod on mine, you said in the video I can just get the foam without the copper ring? How can I do that I can't seem to find it on the website?
Thank you!

Why did the audiophile wear headphones to the party?

Because he didn't want to get caught up in any treble!

Hi, I wonder... it does very well on the 770s, but would it possibly do good as a mld in DT 990s as well?

I have two DT 770 Pro (80 and 250 ohm). I prefer 250 ohm version as I find it more detailed and having a better bass control. I like Beyerdynamic so much that I also own DT 1990, 1770, 880 (600 ohm) and 990 (ohm). I also like Allan Taylor very much and Color to the Moon is one of may favorite tracks, both for listening and testing.

I have a question. Did you check whether it makes sense to brace the magnet to the earcup instead of adding a weight? I mean, you add mass this way too, no?

Did you know that dinosaur, were only the reptiles who lived on land.
The once in the water were aquatic reptiles. 6 year old geek knowledge😅!

I'm really happy that someone like you is making these videos and upgrade's for studio headphones, that's make even better for user's experience. Myself I recently have bought also DT770 Pro 80ohm because I got upset after using HyperX Cloud Alpha and Cloud 2 that they aren't able to hold more then 2 year's without issue, so thought to buy an little bit expensive pair headphones that are approved for a long time of many creators for sound quality and durability. I was planning to buy shortly the kit, I never have tried doing modification to headphones and it would be scary for me to do, but with your videos in 15 minutes is everything possible for everyone, it can take and more, but until you do it properly and correct everything is fine and doesn't matter the time spent.

So, here is a joke: How do you stop a bull from charging? Cancel It's credit card.

And here is a fact: The average person walks the equivalent of three times around the world in their lifetime, just by taking regular steps.
