GL2000 grill mod/tuning fix

Ok I’ve been super lazy so here goes.

The Goldplanar GL2000 is a super polarized headphone. It’s the best tuning ever or the worst depending on who you ask and I personally like it both ways, but stock they just don’t work for everything.

Before and after for reference:

Before you start the mod, make sure you have a nice clean surface to do it on with no dust or metal around.

Start by removing the pads and pad mount ring AND KEEP THE SCREWS A FEW FEET AWAY FROM THE DRIVER AT ALL TIMES, THEY CAN GET SUCKED INTO THE DRIVER AND DAMAGE YOUR HEADPHONES:


Next, remove the driver from the housing removing ONLY the 5 screws circled below:

If you can’t get the driver to just fall out press lightly on the top of the grill mesh with a screwdriver and it should pop out:


Next step is partially optional as it doesn’t effect the sound much but it does effect the stage slightly. The grill has two pieces of mesh protecting dust from entering the driver housing. The left one is the one you would want to keep in for the least amount of effect to the sound but again this is optional.

Now on to the source of the “compression” sound, the tuning paper glued to the driver. If you’re careful you can reinstall this afterwards if you decide you don’t like the sound (fair warning it does get kinda bright):

Remove that and you end up with a driver that can breathe how it was intended to:

Put it all back together in reverse and you have yourself a modded pair of GL2000s with massively improved imaging, detail, soundstage, and far better tuning for the majority of uses, including gaming, which they are totally top tier in post mod (but don’t get me wrong, it’s good the way it comes for plenty of music tastes)

If you have problems with the sibilance they get with the mod you can cut out some felt and put it in the ear pads and it will smooth out the highs substantially.

Bonus: either a QC issue or they decided to put the felt cushion around the driver opening around the same time they changed to the D shaped hybrids. Original (left) and newer (right) and I’m not quite sure what its for, maybe to stop some slight rattle with the pad adapters or something.

tnx for this post - im gonna do some mods on mine based on this . ill use a sorbothane shee instead of felt : https://www.amazon.com/gp/product/B019O38L9K/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1

i wonder if i do the mod similar to the he6 the fuzzor mod but thinner felt with backing adhesive to tame the highs a bit

Worked just fine for treble. That is 1.6mm felt behind the pad adapter.

ok im done - it sounds so much better . its open , wider stage , bass is better . thank God im not sensitive to the treble .i might put the felt to cover the driver to see how it works .
i sealed the gaps with blu tack as best as i can .

If you took any pictures feel free to post them here

i did a hurry up job and the results are greta imo , ill try to do kore detailed work and take pictures next time .

Yea would appreciate having images. Thinking of doing the felt around driver mod as well

my only real complaint after the removal of the paper on the driver was that the gl2k still didn’t have much bass presence but after you do the felt mod on the inside of the cups it really really improves the bass. in no way too much, just puts it where it should be. seems to tame a bit of the ring they had as well without sacrificing anything at all from what i can tell. did quite a bit of a/b testing between the two pairs i had on hand and the difference was pretty big. its crazy what that lift in bass feel and presence gives you for making them sound more natural and i want to say it gives a really enveloping sound and feel. not only in the audible bass region but in the super low sub bass as well and i’m guessing it’s from helping the bass translate through the pads better from eliminating a bit of flex that would absorb the bass and it’s great.

are you using the stock pads or the hybrid pads it came with?

the leathers seem to be the best all around tuning wise but there is a certain sense of size you get from the hybrids that the leathers don’t quite have, but you take a pretty big hit to bass with the hybrids. for competitive gaming i lean towards the hybrids, for single player games and music i prefer the leathers.

also i ordered some big ass super deep leather pads from aliexpress months ago for like $10 and they still haven’t showed up lol. i really want to see if the extra depth of the pads can stretch that stage back to where the hybrids are and retain the bass presence and have the best of both worlds.

I’m not able to find felt tape anywhere locally. Think I can just use blue tack to hold the felt in place?

That’s why I’m hoping to see some pictures before I start my mod.

for the felt tape - if u are in the uSA just get t from amazon

im using the aliexpress 120mm pads , its huge but its alright and i like it better than the stock pads the gl2000 came with . u can even do 115mm and i belive it will fit better.

I’ve had 115s and 120s sitting in customs for months and 110s for my 177x
