Teabag your Sennheiser HD 58X (to IMPROVE the sound) 

This is the most legendary video I’ve ever seen, I didn’t even realise how bassy the 58X’s were until you pointed them out, and this mod works so well that it honestly dumbfounds me. I also removed the outer foam covers and it seemed to widen the soundstage, they really sound beautiful now. Incredible video!

I actually thought you were going to physically teabag the headphones to make them sound better.

Amazing, I did this and they sound perfect now. The bass really was the problem. I can finally hear the gorgeous upper mids and treble without the muddiness. You've earned my sub man.

I'm so glad I could put you down this path, and share this information with you! I've been saying this for a long time, glad you could get on board. Teabags are an interesting idea.

Applied the teabag to my 58x. Can confirm that the midrange cleared up a bit :-). Thanks for the guide!

I did this and it does exactly what you describe - thank you! Previously I had to EQ to remove some of the veil and retrieve detail I thought was there but muffled, now I am happy and don't feel I need to continue buying headphones to get the right sound. And this mod is completely reversible.

Just did your mod with matcha teabag and the result is incredible, the darkness of the 58X is gone! Thank you for the vid. Another further decrease you can achieve on this note is to remove the front foam and use some kind of veil fabric to still protect the driver. I'm still unsure about it being better than stock with your mod applied though, might be too much subtraction. Edit: just tried your mod with the stock inner foam back on and no, the combined mods are superb, better than stock. I'd say this brings the 58x even closer to the HD 600!

fascinating results!

Dongseo teabag!! Pretty much impressed with your mod. Love from korea

Great improvement, thanks. I have a late HD 580 (essentially the same as the h d600), which I love, but it needs the rather bulky ifi hip dac to get the right volume with my mobile. I've been using the HD58x with a simple usb-c dac but I could not live with the veiled sound. This has solved the problem. I used the thinnest teabag I could find so I'm left with a touch more bass than optimum but the veil is lifted.

So I remember reading that the pre-production samples of the HD58x had a similar dampening filter as the HD600, but the bass to low mids were really weak. Removing it helped fix the shrill issue with that particular pre-prod driver setup. I would describe my stock HD58x as having full bass extension, muddy low mids, sufficient upper mids/presence. I've been using HeSuVi with the balanced EQ curve for these headphones and although it's not perfect, it flattens things out enough for my tastes. I'll definitely be trying the tea bag mod! Would help when I listen to music from my phone. Speaking of that, imo the sensitivity of the HD58x works really well for mobile devices! I think the marketing for them is spot-on for ideal use cases. Sturdy build quality and affordable price for pretty good sound quality with the 58x.

nice video man as always cheers!

Wasn't sure if the change in the sound signature would be significant enough to keep the mod, so I tried one side at a time and I've found the change worked and with the bass reduced the highs and mids were more in balance with the bass, so I can enjoy every part of a song more.

Nicely done, something a little different :) Easy enough mod after watching your vid. Can't A/B the results but will give it a week. Thanks 👍👍🔊

Really cool review. I got the current post 2021 OEM 600 series earpads, which have 1dB less output in low frequencies and the Solderdude mode might make 58X slightly lean. Also I replaced the front driver foam with ladies stockings, but the new pads make them brighter than I like. With current earpads the 6XX is slightly more neutral in the mids.

My solution for relief of the muddiness of the upper bass / lower midrange, I removed the foam from behind the outer grills. I then cut nickel sized circles out of the foam and secured one to each magnet with double sided tape. For me the result was perfect.

Dude thank you so much for this video! I didn't even realize you could remove the ear vents that easily LOL

This mod fixed a problem I didn't even know my headphones had lol I enjoy them even more now, the mid bass used to be a bit fatiguing over long periods at higher volumes, but not anymore.

I removed the inner foam, removed the spider cage and the foam covering the magnet from ny hd600. I then placed a pice of nylon to cover the inside of the ear pad. And cut a circle piece from a Red Rose tea bag ro cover magnet hole. Was amazed how much better soubd and overall bass improved. Sound is wide, full. But the bass has taken on a added depth of presence that i find very pleasing. For my ears i preffer this sound over tbe original sound of the hd 600.

HD58x is one of my main headphones, along with HD600, but the X has little more base. As closed backs and wireless/wired I got Sennheiser PXC 550-II. I didn't do any mods and love the way they sound. For the price these are awesome.

Interesting video. Thanks man! Can't wait to try it out once my order arrives. Can you also do a video on the effects of removing the foam between the driver and the grills? I saw on Z's channel that this also has an effect on not just the bass, but also the treble.

A good complement to doing this mod is to EQ in some sub bass. The 58x has the best bass extension out of all the 600 series, but it rolls off way too much. Fortunately it responds well to EQ, so if you do this mod + add in sub bass via EQ, you get more slam in the bass while gaining clarity in the mids.

Do different types of teabags add different musical flavour's ? if so i need one from Jamaica mon i love me reggae music !!!

Finally got around to trying this and I can attest a marked improvement in SQ and FR to my ears. Less veil, exchanging bass for detail. Great!

I did my own version of this mod with a few extra steps... maybe overkill... but here goes... I used a piece of felt as my material (following Solderdude's recommendation). I also found a link to a 3d print file for a decorative piece that looks like the centre ring of the HD 660s. I sandwiched the piece of felt between 2 of the decorative pieces and then stuck the whole "sandwich" over the driver as you've done with the teabag material... the reason for mymethod was to create a small gap between the hole and the felt to avoid reducing the bass too much. the felt directly on the driver reduced the bass too much to my taste. I also did the "curtain mod" which involves replacing foam from the inside of the ear cups with sheer curtain fabric. This retains the bass response which is controlled by the outside of the driver (as you've shown) but also adds a little bit more sparkle to the treble (there's a curtain mod video here on youtube). I'd love to get my modded 58x measured at some point (I don't have the tech or smarts for that) but I love the balance of the tuning I've achieved

I did a "no back" mod It's easy and 100% reversible Make 2 each of nickel (20mm diameter) size of mounting tape with 1/4" (6.3mm) hole on the center (2 rings) 2 ea of fine metal mesh from filter and cut slightly larger than 1/4" diameter (to cover the magnet hole) (Optional) Nickel (20mm) size plastic ring with 1/4" hole (for cosmetic purpose) Put the mesh on the hole of the ring (tape) and cover on the magnet with hole aligned Cover the headphones back cover after it's finished. The audio is more transparent after modification

Looking at the response around @13.07 I can basically do a low shelf filter EQ about -3db at around 2k and get a HD600 response out of the HD58X

i also love my retro marble hd600. best headphone ever made...

I didn't catch this live so you may have answered this question. What I didn't hear in your review was that the HD 58X has an impedance of 150 ohm while the 600 is 300 ohms. Big difference if you don't have fancy equipment to drive them. Drue eludes to the fact that his Sennheiser's sound like, well, you know. I'm wondering if he is aware of that? Probably, just asking. Another good suggestion. Thanks.

I tried it with felt but it didn’t work, with teabag I finally listen to that sound, great!

Confirming as well. My test track is John Mayer's war of my life. That mid bass dropped therefore opening those mids a bit. I used a tea bag.

I just wanted to know how to remove the grill to clean them after a year, thanks.

does adding the teabag on the ear side of the headphone change the sound the same or does it only work with the magnet ring hole?

I teabagged my newly purchased 58x "Thanks!!" now she sounds so much sexier! I also removed the stock front covers and replaced with the dryer sheet. Yes they may rip easy but placements are just pennies per cover.

I must have missed it, but what specific tape did you use between the magnet and the cut-out discs?

ho fatto la modifica che hai suggerito...credo funzioni veramente ....adesso ti faccio una domanda ...secondo te si può smorzare su diffusori da stand la invadenza delle basse sulle medio-basse aprendo cosi come sulle 58x la gamma media tappando con un materiale adatto il condotto bass reflex?...intendo un materiale che lasci passare aria, diverso dalla spugna in dotazione con gli speakers...il principio mi sembra simile ma ovviamente non è un crossover.

Thoughts about teabagging the HD600 to open up the treble? I know the Sennheiser veil isnt that pronounced on the HD600

@8:33 'spare' tea bag - I just call them tea bags :-D Great to make people more aware of modding..too often products are regarded as sacrosanct rather just manufacturer compromises. Btw I have a 2nd hand hd600 I got for £130 so great value to be had second hand too..headphone drivers don't tend to degrade as much as loudspeakers, though pads may need replacing (which also affect the sound).

another mod is to get memory foam and trim it to small balls and then place it between the caps and the driver ... but keeping the original foam on 58X this will make almost the same but to me with more progression and extension

Recently getting HD600 for my personal use. Which amplifier would you recommend with it? I currently have L30 and TA-10 at home.

If you look at the capsule of HD600 (15:38) - in the region of 8-10 hours and 2-4 hours you can see plastic, black petals. Because of this, the mid-600s sounds haunting/screechy, coloring and at the same time hazy. On HD58X capsule (26:34) these petals have already been removed - so midrange is more pleasant and more correct.

Surely, I also noticed that peeling off the outer sponge of 58X improves overall sound by giving some sense of openness but using it for more than a year in this state, I didn't feel the need to cover the holes with something. In fact, EQing impacts the sound much more than that. :q

I steeped mine for about a minute. Magic.

Do you recommend Magnet Mod ?

Hace 2 días probé este mod por curiosidad, ya que consideraba que mis 58x me gustan como vinieron de stock. Puedo confirmar que este mod, sin matar los bajos, aclara un poco los medios, gracias SR!!

I own this set and all I did was just removed the outer foams and I called the day! I'm ok with the way it sounds

What about if you just take out the back pading? Isn't it will reduce the base as well as improve the mids/hights?

Well, well, the 58X Jubilee. I own these. The imaging on these are ridiculous.....in a good way.

I just removed all the foam in my 58x, front and back, and the sound is now $200 better. Tea bags? I use them to make tea.

A great no risk mod. Have you (or anyone else) experimented with magnet modding?

I wonder if silkscreen would work, be interesting to try due to the different mesh sizing also

Would love to see a review of the 6XX from u

I was just considering getting these for my birthday soon!

Could the tape damage the headphones at all? Thanks for reading!

Hi, is it recommended to remove the foam on the grills so I can see the driver?

I would love to see a video of all mods for this headphone.

Can I get the link to the foam? My 58x is in transit right now and I want to get prepared

I'd mod it to give even more bass, I had these headphones before and they aren't very bass heavy at all. After these I upgraded to the HD 660S and then I upgraded again to the HD 800 S. After getting the HD 800 S I figured I didn't need all 3 pairs, so I sold the Jubilee's to a friend.

You can get a wider soundstage by putting a magnetic metal mesh over the drivers, and if you want to keep some of the bass, just make 2.5-3.5mm hole in the mesh

Oh My, more troubling content. Kidding..

So I guess a modded HX58X is the sub 200$ endgame? Currently I use bass modded AKG K702 before that I had Beyerdynamics DT990 Pros which are junk in my opinion. So should I buy HD58X and mod them?

Another mod for those want more high bass and lower highs is using Coffee filter between the driver and the foam in front .

I was excited to see the graph of comparing the frequency response. VERY disappointing that when you got to that point of the video that you did not show it and instead made the HD600 flat.

Dang just removing the pads really clear out alot of muffle. Now in busy songs i can hear symbals sounds properly.

I just happened upon this video while looking for something else. Interesting because I did something very similar. I lightly glued some "Randy's 3/4" brass screens" over the hole on some Game Ones with good results. You may want to try it.

When i got HD58X and compare them side by Side with my HD 660s or the others 600 and 650 i get exactly what u said and honestly the difference between HD 660s is night and day mostly on separation and imaging

The tea bag rolling will be a whole new thing 😅.

Is the current hd58x different and this mood don't give the same effect?

What dap would you recommend under 120 euro

I don't understand, if you don't like the bass can't you just eq it lower? does this sound better than just EQing?

Interesting........ My issue with the 58X isn't the bass, it's the midrange. Too forward. What do you have for that?

Is there a reason you don't EQ? Mods like these have always struck me as trying to accomplish the same thing as EQ but with way less control, but maybe that's just me being ignorant.

I’m leaning towards the 6XX. But damn. They around. $280 now I believe plus tax.

Can I do these to beats?

I want the legend,s all😊👍👍

58x or pc38x? Sound quality wise?

nice video - I wonder if my untrained ears would hear the difference ..from the graphs - it looks as if we are talking about 2-3db? Or not...?

Does this reduce soundstage?

That video title... brave.

I tried the mod with the green felt...I did not like it personally. For me, it ruined the bass decay too much. Felt like the bass fell off a little which is fine but the decay dropping too quick ruined it for me.

On your screencap, was that a teabag lol

Earned a sub from me

Why not remove the padding inside so you see through like the 650. Instead. Maybe that will do the trick and look cool too

I can't hear half of the sounds after applying the mod.

Doesn’t the double sided tape. Close up the hole ? You didn’t explain that The tape alone would change the sound. I’m confused

Teabag 👉🏼👌🏽tehe

My boy actually pronounced it "A-murrican" 6:10

15:47 thank God, lol

You could also just buy the hd560s ;)

NOTE : I didn't try the mod yet. I have the HD58X for 3 years now (Massdrop just released it and it was $149) and I hated it since day one. Mark's description of the sound is spot on : "Cloudy and meh...". To that, I would add "Upper bass/lower mid congested and a generally uncrisp audio experience". When my brother just bought himself a brand new HD600, he came home for a comparison with my few headphones : (in order of preference) beyerdynamic DT990 Pro AKG K7XX HiFiman HE400i Fostex T50RP mk2 (with mods) Sennheiser HD58X Jubilee I first put the HD58X... and then HD600. Wow, I wasn't expecting so much difference, but for me it was huge. Then I compared with all my other headphones, and I understood why the HD600 is so praised. It was my favorite of the bunch, followed closely by my good old DT990. For my brother it was a tie between HD600 and DT990. For those who wonder, yes the HD600 is much better than the HD58X. For me it's like night and day. Now it's time to try this Teabag mod to find out if this HD58X is a hopeless case.

Removing the outside cup foam ruins the sound. It leaks more sound and ruins the headset for me. Removing the inner foam makes it sound harsh.

The best earphones would be a hd600 but earphone 😅

Why not use PEQ instead? It's free and you can tune to your liking.

Hey, man. Did you touch my drum set?

Glad you told someone not to mess with his stax you go straight to hell if you do !!

Just remove that bit of foam! (Next to the grill)

No point, a decent amp will even out the bass, improve the sound stage and imaging if it bothers you. Not a FiiO, or Shcitt, they won't do that.... they don't have the technology. Zen Dac does it perfectly.

Can't you just EQ?

There's nothing to improve on 58x. And as for HD600, even M50x are much better headphones.

Plz stop talking
