Pro700 MKII Bass Mod

post #1 of 37
Thread Starter 

UPDATE Dec. 14, 2012--Final FINAL Version

 

Text in bold is to convert your headphones into the GBH-1000 (pics and more at the link--this is an older version)

 

Materials

-Electric Tape

-Scissors

-Philips Screwdriver

-Beyerdynamic DT250 Earpads (or M50s pads, but there is less bass impact)

-Cotton  Toilet Paper (sounds cleaner to me, and for the GBH-1000, the cotton isn't squeezed out due to the pressure of the earpads wedging them out. Rip off a piece about 20in., fold it in half so it's 10in. long, roll it up, and stuff it in. 

-Clear duct tape

-Beyerdynamic Gel Earpads (Thanks G3NRAL KARL)

 

Procedure

1. Throw away the stock earpads 

2. Apply your DT250/M50 earpads

3. Stuff your cotton toilet paper underneath the earpads. I put about .5in of space between the driver and the earpads. The cotton serves two purposes: to give it extra bass, and to secure the oval pads on the circular cups.

4. Listen

 

These pictures are now old for my newer version. Just imagine them without tape around the circumference of the headphones, and with cotton underneath the pads.

GBH-1000 Procedure 

1. Remove stock pads

2. Unscrew the four screws to separate it from the enclosure

3. Leave the four screws in the holes on the silver plastic before putting on the gel earpads. This makes it much easier to screw it back in. 

4. Apply the gel pads and use clear packing tape to wrap around it. Make sure the tape is tucked inside the headphone.

5. Screw the silver circle back into the headphone

6. Stuff cotton toilet paper/tissue underneath the earpads

7. Listen.

More pics here  and here.

 

Results 

- Bass impact is increased. Even more 

- It effectively removes that "artificial" sound to where everything sounds distant and non-impactful--mainly because of the stock earpads

- Increased separation and blackness

- The bass sounds deeper and smoother

- Increased Midrange UPDATE: I found out that when you put cotton/tissue underneath it, the midrange is recessed a bit. Standalone gels will make the midrange sound more airy. 

- The treble is smoother

- Increased Isolation

 

It will be about a week until I can really compare the treble to my HFI-780s because they are not in my possession right now, but, from vague memory, I think that the 780s are brighter than these. 

 

Update: Yep, they are, and, from a bassheads perspective, sound worse than the pros in every aspect. As I posted before, the highs on the 780s are really fatiguing on my ears, so I can't listen to them for prolonged periods of time. The comfort sucks on them too. I tried putting the velour pads on them and the bass was basically non-existent. After listening to the 780s again, it feels like they have no bass whatsoever in them compared to the pros. I guess these headphones are a hit or miss depending on ones ears because of their S-Logic technology.

 

 

EXTRA: Upon opening these cans up, I found out that these are actually semi-open. Behind the rubber (what the logo is on), there are 4 holes where the sound travels out. I put my hands over the headphones just in case, and when I did everything sounded boxed in.

Volume settings. Top is seek, bottom is volume. I made it that way so I can adjust the volume more accurately (smaller dB intervals when the bar is longer), but I usually keep it at that spot.

 

I have my receiver's bass setting on +10

 

I would make an attachment with my eq settings in it, but I can't make attachments for some reason. Just copy them visually.

 

To get the vst to work, you have to install the wrapper, download the effect, navigate towards the effect wherever you put it using the VST Setup in the taskbar, enable it, and tweak it. You may be wondering why I have two stereo settings, and the reason is that both of them use different algorithms and whatnot to achieve a wider stereo, and they sound great when combined.

Why do the pads look so janky and loose? They barely look attached to the headphone.

In fact, it's quite the opposite. The earpads are much more secure than what the pictures imply. I can't even take the earpads off safely without unscrewing the headphone and peeling off the tape. I didn't tape them up because I wanted to. The DT250 pads are ovular in nature, and the Pro700MKII's cups are circular. Before I taped them up, there was a noticeable gap between the headphones and the earpads, and the sound leaked out very badly. That's where the tape came into play. On the sides of the earpads, you can see that the DT250's were stretched out, and on the top/bottom there is more room. This is because the circular nature of the cups.

There isn't another type of earpad that we could use instead of the dt250 if it doesn't fit that well?

Anyway, looks interesting.

I haven't tried out any other earpads except for the stock M50s pads and the DT250 pads. Both sound very similar, but the DT250s sound more refined in the bass and treble areas. You may want to look into the beyerdynamic 770/880/990 earpads, but, as stated in this review, they really take out the bass, and you also have to tape them for them to stay on. The M50s are easier to put on because there is more "lip" on the pads than the DT250s, but sound leakage is evident with these pads too. The extended lips allow them to jiggle around the cans more.

 

Oddly enough, I tried taping up the DT250 pads on my M50s, and the bass went away, but with no tape it sounds the way it should...oh well. I don't listen to them anymore tongue.gif

 

So far, the DT250 earpads are the best earpads to get for these cans.

 

On another note, I am thinking about ordering some of the Beyerdynamic gel earpads, but they cost too much.

Are you talking about the Clear Beyer Gels?  I have them, they didn't fit my Beyer DJX-1's or the DT660's very well.  They might attach to the MK2's.  I did make a slight mod to the gel pads though - I cut small slivers in the lip to see if they installed easier - they do just a little but not by much.  If interested let me know.

 

I also like your mod too, wish I gone to greater lengths like you did when I had the 250 pad MK2 combo.

What are these "gel pads"? I may bite on this, I hate how the M50 pads feel, so I've been looking for some sort of alternative.

Edit: Eighty dollars? OMGWTFBBQ. I want these a lot, but I'm a wee bit afraid to drop half my paycheck on these when I'm not even sure if they'll fit on the headphone :<

The gel pads are very comfortable, and they form around your head very well, but the sweat makes them stick to your skin. I prefer the comfort of the DT250 pads over the Beyer Gels mainly because of that. The gel pads also isolate better than any other pad I have used, and they give me more room for my big ears. The sound characteristics between the DT250 pads (with cotton under it) and the gel pads are pretty similar. Check the updated post for details. 

 

They used to cost about 37 dollars, but they cost way too much now. 

 

They are too large for the headphones. There is about a .5cm excess all around with these pads on.

Since I have long hair, I don't get the sweat problem, and I could definitely use the extra isolation since I plan on actually using these for DJ work and whatnot. I will probably buy them even though they cost a lot. Know anywhere or anyone that I can get them for the least from?

Also, could these pads possibly be used on the Ultrasone Pro900?

I believe the gel earpads have been discontinued. I looked it up on google shopping and it's showing them at sears (of all places) for around $80, but they are all dead links. I guess you can only get them used. The pro900s look to be around the same size as the pro700mkII's, so the gel earpads will most likely have to be taped up for these too. They are, after all, made for the Beyerdynamic 770/880/990 series, which are very large headphones.

Alright. Thanks for the info, it's really cool that you answered all of my questions.

I think that I will do this mod and then sell my Pro700mk2 on this site or eBay to buy the PRO900 (since they essentially serve the same exact purpose) when I get my next paycheck.

 

Later, I'll most certainly see if I can snag a pair of gel pads around here (velour is not exactly known for its isolating properties, after all).

I'm just in love with these pads. XD

Before I made my GBH-1000's, the DT250's isolated better than the M50s pads (with and without cotton underneath them), which I think is good enough. With the way I have them set up now, It's like having an air-tight headphone on your head (if you put your hands around the ports on the ends of the cups--these are semi-open). With my hands off, they isolate a bit less, but nothing to complain about. It does get irritating when you're walking in windy weather because the wind will get inside the cups and make that ear-in-seashell sound.

Do I have to tape them on like you did? Despite the obvious chic of Hello Kitty, I'd rather keep them looking more or less the same as stock.

They have to be taped up, unfortunately. You can always try gluing them on there, but they may become irreversable. The gel pads are too big for the headphones, and since the outside of the pads are made up of plastic that isn't flexible enough to be squeezed on there, you wont be able to put them on there without tape, glue, or some other adhesive. Once I get the dt250 pads that are on my m50s (wont be able to get them until this weekend, most likely), I'll see how they sound stacked up.

Besides the gel + velour, the cotton + velour is the second best sounding setup, and I have tried EVERY setup with the stock, velour,
m50, and gel pads.

so assuming i ever manage to get my hands on some gel pads, there is no way they can naturally fit on my pro700's without using glue or tape?
