Beyerdynamic DT770 Headphone Repair

Beyer DT770 headphones have a known issue of having distortion show up them which is caused by hair getting into the speaker area and vibrating against the speaker membrane. The sound of this mimics a blown speaker and you'll think your headphones are history. This brief tutorial shows the parts disassembly and explains the simple cleaning procedure. According to the Beyerdynamic website, this cleaning will in most cases this will cure the problem.. It did in mine, and it's relatively quick to do, and free! Enjoy!

Yesterday without a reason, while i was listening music at a very low gain for 2 hours, suddenly they began to crackle like crazy on the right side. You know what i mean when you almost fall in depression, thinking your high quality and RECENT stuff breaks apart. Then i googled it, and saw people saying it was hair. Thanks to infos such as your video here, i could just solve the problem, and feel waaaay better now! Just to say, mine was full of my Jack Russel white hairs, and i could have spend 2 hours removing them. I just concentrated on the middle where the membrane is. Thank you very much!

[@svenglansberg]

Great tip, but some CAUTION is needed. 1. When you try to remove the speaker (after the glue dots no longer hold you back), be careful when it snaps off. When it finally came off, the force I applied made it spin in my hand and I accidentally dented the speaker cone. I was able to fix it by sucking the dent back in position with a straw. 2. Examine the speaker leads that goes from the terminals and in under the speaker cone so you really know what they look like. They look deceivingly similar to a hair strand. (I almost damaged mine, since I thought they were hairs.) 3. If you use tweezers that are made of metal, note that right behind the speaker cone is a quite strong magnet. So your tweezers can very suddenly be drawn towards the magnet and will risk damaging the speaker. 4. The surface of the speaker cone is sticky and gooey. My headphones were 12 years old when I did this repair. So the hairs that were stuck left a groove in the surface when they were removed. After a while it was hard to tell whether I was trying to remove a groove or an actual hair. I guess I would do better with a magnifying glass.

[@alexwoods4825]

Thanks, this was an essential addition to the video. I also dented the speaker cone (thanks to the magnet and the tweezers) and was able to fix it with a straw. So nice to have my beautiful headphones working again!

[@Heart0rHead]

And don't touch the membrane. I was removing those hairs with my fingers and apparently messed up the membrane on my DT990. Now they don't sound like they used to (awesome). Bass is weak, I'm so pissed. After further investigation it turns out that the magnet is covered with some gluey substance and if touch the center of membrane it will stick to the magnet and it's over. Even the vacuum cleaner could not suck it back.

[@komentierer]

About the deformed speaker cone: I was wondering if there could be long-term effects on the sound quality.. because my vacuum cleaner recently came too close to my pair of dt880s and they stopped working for about 10 minutes, until they suddenly started working again. So I suspect the same thing happened to me (just the other way around) and I'm not sure if this affected the accuracy of the sound. How did yours hold up afterwards?

[@itspism]

Bought a used pair and thought I got screwed over. Turns out they just needed to be cleaned. Thank you so much for the guide! You're a life saver!

[@riccardominicozzi8717]

This works, but be mindful on newer editions of the DT770 (I also have a newer DT990 that experienced this) there's way more glue, a method I found effective was getting a q-tip soaked in acetone, and lightly brushing the glue, this helps dissolve it. Then taking a thin metal spudger (soak that in acetone too), carefully wedge inbetween the housing and the driver, and pry apart. Then it'll come apart super easy. Don't be scared either guys! These thing's are pretty durable, and even after popping the driver out of shape and being a little rougher than I should have, it all came back together and sounds like brand new again :) Thanks yukka2 !!!!

[@djvidual8288]

It really worked. Had so much fear to destroy something, but it worked! Thanks for giving an overview of that not so complicated build up. To all others: Consider that your left earcup has 3 tiny little cable, what you can't see in this video, running into your driver additionally. Don't be afraid, you need to work around them.

[@Menwulf20]

At first i thought those were hairs to. Thankfully i noticed they weren't. lol

[@percashic]

So nice man, i was getting nervous because my right side was sounding distorted, but then i just opened the cup rmoved three tiny hairs. Now sounding new again

[@kato9458]

same

[@Sonusproject]

Thank you!!! Just repaired my DT770 following this tut! No more distorted bass! I found out the speaker cone of the right driver was a bit deformed. I used a vacuum cleaner on low suction power to get the cone back in it's conical shape. Then I initially sucked it a bit too much forward soI used a hairdryer after to blow it all back in place. Funny how these everyday tools know make me have a decent sound again! Thanks miles for this vid

[@garytangnet]

Thank you! Solved my high frequency distortion which just started yesterday. I used compressed air, which compressed the center. Used a small Mickey Mouse with a suction base to pop it back out. 4 year old DT770 works perfectly. Did not find any glue, just really tight clips holding the speaker in. Inserted the speaker slightly off rotation, but it stays perfectly and everything else mounted back correctly. Your post really helped.

[@zanarisrobo]

Worked for me, was worried my DT770s were damaged already. Opened the earcup up and removed some hairs and it was fixed. Thanks alot.

[@willw3015]

I just took off the ear cup and black foam piece to clean any hair off the white papery part and that's all I needed to do to fix my right ear buzzing at low frequencies! Thank you for the in depth video.

[@KitsCloud]

WARNING for any others. My dumbass somehow snapped the cables. I tried to be very careful but the left side has some extra cables that are very flimsy. Thanks for your help though, because you were spot on. There were some hairs which were causing issues and I bet it would've fixed my distortion if it hadn't been for my clumsy hands.

[@45eno]

I feel your pain. I just followed another guide and put a hole in the white paper. Luckily i can't hear a difference. Going to try to use some finger nail polish to lightly glue the flap in place.

[@birdyvogts]

Hey i just came across your video because on low frequencies and using a high gain headphone amp i experienced a vibrating/buzzing sound. fixed it with your tutorial in less than 10 minutes. thank you so much!!!

[@sashabloem]

Thanks sooo much yukka2! A quick solution for my poor right driver. Pulled out 4 cat hairs with my twisters, and voila! Got a new dt770pro! You're the best!

[@alternatingbitmusic]

Omg I think you just saved me from buying a new pair. I thought the bass cone had been shattered or whatever (probably old school speaker talk) but anyway - I decided to give it a go based on your instructions. While I didn't find any significant hairs (apart from one TINY curled one that was on the outer rim of the inner gel-like cone, I did remove some fibers of what looked like a frayed velcro tape or something but that was just on the inner shell of the housing which I doubt would have made a difference. At any rate, I did clean the sponge using a tape roller, and then used some canned air to clean out the rest (not aiming it at the actual gel speaker). Seems like it did the trick! You are a genius.

[@carlosgilpinheiro7510]

Good work, I repair my DT770 Pro too. No rattle now at all. Thank you

[@rskie]

Have a limited edition black pair of DT990's and I can confidently say that the driver is a lot more secured on newer pairs than what's shown here. I couldn't manage to loosen the clips securing the driver so I used some compressed air on the back of it, then added some folded up TP (I'd use cotton but I didn't have any on hand) where the cotton ring is on the headphone shell, to give it some more cushion as I suspected maybe it was rattling on the shell/casing. Reassembled and no rattle, all works great!

[@petrilaakso7927]

Thank you Sir! My distortion problem eased somewhat better. I now can listen louder until distortion kicks in. I didn't see any obvious, hair or so. I just blew to membrane.

[@yukka2]

+Petri Laakso some of them can be hard to see and blend in, colorwise. That's why I used the magnifying glasses to inspect. Glad it's better for you.

[@toemass202]

hey dude, thanks for this information. I had a low bass rattle in the left ear cup and i took the whole thing apart down to the silicone, and some hairs were nestled in the driver! I plucked those bastards out and tadahhh, no more rattle! So thanks, this video helped me what I needed to do.

[@mellytek]

thanks for vid , i was really fortunate as did not have to take the hole phone apart but after taking the foam away i could see a long hair sticking out of membrane , removing solved distortion , TIP GUYS, check them regularly before the issue arrives :)

[@tigrannerkararyan2632]

Thank you sir. There is a short hair in left membrane. I take it off, and the problem was already fixed. Sounds perfect 👌

[@nineteen76]

2020 and this is still relevant! My 1.5 day old dt770 started crackling on the left and I was so worried. Just took it apart and put it back and it was sounding like new again.. like it should.. lol

[@felicityc]

same. had this weird just... noise in my right ear. take it apart, long hair just hanging there. now it's perfect. crazy.

[@JanSandahl]

I need to try that. I fear I have a broken driver. It's only audible in the bass range. Must check. Your comment gives me hope. :)

[@naturalbornchilla]

@@JanSandahl had the same problem, did the thing and its good again :)

[@Nilzzzon]

On the recent model of 770 Pro 80 Ohm, the last part is not glued. I just fixed mine with bending the last part off with my fingers. I first used tool but it just dented the plastic. And, surprise - a hair had made it through all the layers of padding and woven materials. Picked it off, made sure it had no more hairs on it - and poof, problem fixed. It was a long time ago since I was this happy!

[@FDBK4REAL]

So helpful! Very grateful for you and this video. VERY carefully took it apart and put it back together. Had two tiny hairs stuck in there. Good as new now! Thank you!

[@pomperiposse4373]

Thank you! repaired my dt770s with the help of this one! almost bought a pair of new ones but it was just a hair!

[@JonClarksonMusic]

Thanks so much! You saved me a couple hundred bucks. My trusty DT770s are as good as new now.

[@michaelsolano8733]

Just fixed mine thanks to this video!!! Thank you sir!

[@karlapaparla]

Thank you. Did repair my Studio Custom this way

[@Thestrandedtraveller]

Thanks man! My favourite headphones are now buzz free 🙂

[@no2thenwo737]

My DT770 and the DT990 Editions have the distortion straight from the box. I found that to avoid the distortion with these, I leave the bass setting on my amp to neutral. As soon as I turn the bass controller up, full distortion! They sound bassy enough without the boost, but it's still annoying. I expect more out of Beyerdynamics. The DT990 Editions drivers sit in a clamp washer which is very hard to remove without special tools.

[@litarea]

Hey man, I'm sure you get a bunch of these, but thanks so much for this. I bought a pair used and was really disappointed in the distortion in the right ear, but thankfully I found this and they work great now.

[@yukka2]

+Matt Plotas - awesome to hear that you were able to fix them.

[@litarea]

yukka2 well, the left ear is still louder than the right so they may be garbage regardless

[@reavl6494]

If the driver build really stuck together, you could try to take compressed air or a strong hair dryer to blow some hair out. Mine was glued well and tabs were really hard, and I've read many people on here damaged their stuff. Instead of risking breaking it I blew some high pressure air through it and i could feel some dust or hair come out. May be a less invasive fix if you can't fully open it, and it might work, and less risky. I might've just moved the junk around, so don't know if its just a temporary fix.

[@naminnooman]

Thank you! My distortion problem solved!

[@RaphaeltDrechsler]

brilliant! This did the trick! Thank you so much

[@sociologicals2279]

lifesaver. thank you, from the bottom of my heart

[@Menwulf20]

On my 2 year old dt 770 pro there was no glue i simplly cut the top of one plastic-spring off with a cutter. After that i was able to get somthing unter the cup to slowly push it up.Then removed the hair. After that i replaced the cut off part with hot glue. Works fine now.

[@idleave]

This was perfect! Thank you! Just fixed my pair thanks to you!

[@charleswheeler3418]

are those the 250ohm ones? if so do u know the wiring arrangement for the main cable and left driver? managed to pull mine apart. The dude at the shop couldn't do it, but after seeing your video I see its easy and you've just saved me 60 quid on a new driver!

[@jt9944]

Thanks for this information, I`ll try to look inside of mine DT770. And if it`s right, I`ll call to my previous work. They have 8 units and a pair of them has such a problem.

[@DARKEAGLES1]

Thank you. I was able to remove the distortion from my right ear cup like that. :)And yes once you remove the glue and pull it out it will snap off with some force. Take it slow and easy and nothing will happen tho.

[@ManuelSahagun]

thanks so much! it worked as you predicted: one tiny hair...

[@cubex4534]

Thanks from france I repaired my headphones !

[@yukka2]

Mine are all working fine, so I haven't; taken them apart in a while. But I'm remembering that the hairs in there were white. ( of which I have none) Seemed almost more like fibers. I'm wondering if this was not a product of manufacturing/ quality control.. Any of you guys notice this as well when you took them apart?

[@whoho1]

Thanks for uploading this video :)

[@dimpelgimpel]

How did you remove the driver from the big ring, which it is clipped to?

[@SamHocking]

I've done mine too before finding this video and uploaded a video. I don't know why Beyerdynamic use sticky driver diaphragms. Some hairs are stuck so hard the hair sometimes breaks before you can get it all off. I dusted some talcum powder on them so new hairs won't stick.

[@viddicake]

Thanks a bunch for this! Works perfectly!

[@casperorillian7393]

This worked thanks. Although I did have a hell of a job getting the ear cup back on.

[@yukka2]

Sometimes a spoon works well for that.

[@tab242]

thanks. I wonder is mmx 300 gen 2 the same construction type...

[@ikamy]

How did you remove the tap? mine is seems glued, I fear to tear them up

[@atlantean1209]

Thanks man this helped me fix the same issue!

[@eviltroops]

hey man.. i got dt 1770 pro, and the right side didn't work. so, what is the common issue causing this problem? and how to fixed it?

[@Koozwad]

I have a hair on the actual magnet behind that thin transparent layer causing buzzing at low frequencies. Any advice?

[@MarkusTF]

I took them apart several times, removed some hairs, and it would still buzz on the right side. I've found a solution though, when I put them back together without putting the black ring to tighten it together in the end, for some reason there's no buzz / distortion. Any suggestions on where the problem can be found then? Well they work for now at least. Just the earpad is what holds everything together now

[@MissouriMatt54]

Thank you for the video!

[@derpatricktv]

Also Fixes MMX300 thank you so much

[@namename2674]

Not only hair, some metal dust too. Checked my dt860 membrane with magnet and it was magnetized.

[@djvidual8288]

What Ohm version do you use? My 80 Ohms do neither have that metal grid nor that orange surrounding on the driver. Kind of lower cost production? They are 1,5 years old. Mixed feelings about this.

[@retroracingshirt591]

I had to take mine apart also, bass was rattling and those damn hairs were going right thru the transducers diaphragm. Had to pull them with pliers.

[@HAL_NlNETH0USAND]

I cant seem to remove the speaker from the bigger paper thing. It's just held in so many places

[@Morg7n]

bonjour j'ai acheter un dt 770 pro 80 ohm pour le studio et faire des instru rap mais le son est vraiment bas et je sais pas si c'est normal mais c'est un petit jack

[@alfabm8071]

yoo, just watched your viedeo, i had this ratteling noise like something is loose and tryed to pull it appart but was kinda scared a the end t not breack them, i tput a little bit of pressure on the platic bubble and the ratteling decreased, i did it a few times, and the ratteling is away

[@thetinpin]

Holy crap you're awesome!

[@zplusplus8610]

oh finally, thank you very much, it worked :)

[@naturalbornchilla]

thank you much!

[@KrisSugga]

Thank you for the value! I still have no sound coming from my left speaker, all the wires seem good and still soldered. Should I replace something? any idea on what could solve my issue?

[@Menwulf20]

This fixes a crackling sound not an entirely defective driver.

[@usmuse]

I have a different problem. Somehow my red wire was cut mid curly cable I have stripped the wires for splicing and reattached but am not getting any sound still out of the right side. Anyone know a trick I am missing?

[@manwav6933]

Sir, thank you for this !

[@ProAudioIQ]

thanks!

[@MIHAO]

nice, thanks

[@Abbe41]

thanks

[@felicityc]

wtf. it actually worked.

[@ChrisDunne.]

My left speaker is completely broken now, it doesn't produce any noise.

[@micha8469]

I have a signal pinout broken in my DT 770 Pro 250 Ohm in left speaker. Is it possible to open the speaker (the part where pinouts are situated, I have already disassembled speaker from the casing) and replace pinouts? Solder cables instead of pins or something? New speaker costs around 49 EUR which isn't cheap.

[@mezkoo]

Hello! You said a new speaker is 49 EUR, where can I buy one? Need a speaker for DT770 Pro 80 Ohm

[@micha8469]

You have to look for distributors in your country and contact them: eastern-europe.beyerdynamic.com/distributors/worldwide.html

[@8713HyfCc]

I have removed the glue from the driver on my dt880s but i still cannot get the driver to come loose. Any suggestions?

[@yukka2]

Ben McDonald I have not had this issue, but as a suggestion, I would not wedge the screwdriver under the bottom of the speaker to pry it out, you might damage the soft part of the speaker. Try getting a small screwdriver blade under just the tab button and see if you can get a bit of lift there. Or wedge a small jewelers sized screwdriver in near one tab while trying to lift from another. Perhaps it's got some extra glue in there. If it is a glue issue, at you own risk, maybe try warming the tab areas gently with a hair dryer to soften it up? Good luck.

[@SuicidalTwinkie]

Thank you for this video!!

[@yukka2]

+Cameron Osborn You're welcome. I've got numerous pairs of these. Gotta keep 'em going!

[@SuicidalTwinkie]

yukka2 I didn't know it was that simple to take the driver apart, I thought it was all one piece that didn't come apart. Before knowing any of that I used an electric dust cleaner (equivalent to a can of compressed air) to try to blow the hairs out of there. Which ended up smashing down the cone of the driver, but I didn't know that and thought I permanently damaged the driver. Thanks to your video, I was able to fix both of the issues. lol

[@HouseJunk1e]

THANK YOU

[@mhhuusko]

Thanks a lot for the video! Just noticed today when doing headphone tests (www.audiocheck.net/soundtests_headphones.php ) that the right side bass rattled a lot on the low frequencies. I opened the headphones as far as to see the white diaphragm and pulled out a couple of hairs pointing right into the driver. Now the rattle is gone with a five minutes worth of work!

[@SikforSenses]

It worked! Thank fuck!

[@matic_horvat]

So i just got mine and they sound like they are not centered. When i play a kick its like its panned to the right a bit. Could this be a hair?

[@yukka2]

It's unlikely, but it can't hurt to look.. This repair solves a distortion/ fuzziness problem only. If it was me, before I took them apart I'd first check the DAW meters and make sure it's output is sending equal signal to both sides. This might be easier with a sustaining sound like a bass or synth, then check your interface levels as well. If it's connected a headphone amp, maybe cycle the volume knob a number of times to overcome any scratchiness, resisitance. If you still think it the headphones, try listening from a different source; Ipad etc. if it's still off balanced, check the solder connectors on the headphone speakers. Make sure the wires have good connections. Also, if you wiggle the plug end of the cable and it gets better you probably need to replace the 1/4" plug. Let us all know if you identify the problem/ solve it. Good luck.

[@matic_horvat]

It's not DAW, since i am hearing this in everything i plug it in. Checked on a frequency test PC and phone, it starts panning to the right (losing sound on the left) at about 160 Hz. I will not be opening up the headphones since i can send them back with guarantee

[@bagwon]

ditto. thanks

[@mezkoo]

Hello! Nice video, +1. I need to buy a speaker for my client's Beyerdynamic DT770 Pro 80 Ohm, can you help me to find a speaker?

[@yukka2]

I have no relationship with BeyerDynamic so I cannot help you with that. Perhaps try eBay, or buy a used/ damaged pair and use it for parts.

[@DTorn05]

Try spraying canned air directly through the mesh into the driver to remove debris...much easier fix for me

[@EyesReye]

The new 770 versions their drivers are so fucking secure, that you'll break them before you get to open them.. Happened to me and never doing that again, basically wasted 150$. I got a new pair and the bass crackling came back... even when I added another layer of that foam in the hopes it would catch all the hair now... I might try your 'fix' before contacting them for a replacement... I rather not have my headphones gone for weeks before getting a replacement send over.. because my earplugs can't reach the PC from where I sit and I simply can't just move my PC closer to me lol.

[@innocentage8481]

My hair is inside the membrane what to do?? Please helpp

[@Menwulf20]

its the wires most likely. dont remove them

[@Gwynsladle]

I don’t hear any crackle until i raise the volume above 80% on the left speaker. And it doesn’t crackle on the right ones. What should i do. My dt770 is barely 3 months old and the dealer on my country is being a dick and doesn’t believe me because im a ‘casual’ user.

[@mitfuhlenderzuhorer5521]

Could i put the dt 990 ear cups on the dt 770?

[@yukka2]

They look similar, but I can't say personally because I don't own any 990's . Beyerdynamic does not list them as being the same. I did however find this in an Amazon review of the DT770 pads: "Also of note, just to satisfy my own curiosity I tried the pads on my DT990Pro-250's. The pads fit fine and were plenty comfortable but the sound was absolutely horrible. The fun natural smile frequency response of the 990's was replaced by an enormous wall of low-mid mud. Despite the fact that the pads look similar and fit without problem they are acoustically very different from the 990 pads. These pads are much stiffer and designed to complement the acoustic properties of the closed back 770's but will drastically and negatively alter the sound of the open back 880's or 990's which have much softer and less isolating pads. If you need to replace your 880 or 990 pads do not purchase these but instead get the EDT990V pads"

[@mitfuhlenderzuhorer5521]

ok, thanks may i just have to try it ^^

[@Fentiman]

I'm an idiot and threw my pair against my desk out of anger. The left can is fine but no sound comes out of the right. Does anyone know if this is fixable, or have an idea on which of the parts is broken?

[@KristerNielsen]

You sound like Agent Smith from The Matrix

[@leonardocampos5524]

i came to see why my monitors died, but i can’t hear anything in the video 🤔 . . . . . . . 😆

[@michaellogin9835]

Could you help me disassemble Beyerdynamic DTX 501p? That is speakers themselves cloud.mail.ru/public/Didm/kxEzHQEST . There are no screws, so I don't know how to open them without damage. I've got no experience in such a business, so any help or advice would be greatly appreciated.

[@nitronixus9402]

yeah..... in my case its the T51i that broke...... TWICE..... and i have no fucking idea why it happened... first one broke i sent it and its still not returned, still waiting for it then the company where i bought it lent me another one to use while waiting for my original one.... didnt even use it that much just got the most use of it a day ago and when i got called for my homework and returned, BAM right channel is out....... This headphones fucking cursed

[@lyndajones1133]
