Pro700 MKII Bass Mod - Page 2

Correct.

I'm in the process of double checking all of the earpad combinations to make sure that the beyer pads are needed to get the sound described. Unfortunately, when I removed the duct tape from the pads it stretched the plastic that holds the gel and foam in place making it feel a bit wrinkled, but it's not too bad. So, for any potential modders out there, refrain from using the type of tape that leaves residue when peeled off. It may help with that problem. If you did, just use alcohol to take the residue off.

EDIT:I finished with the combos, and I'm having second thoughts about the "GBH-1000". The 1000's sound deeper and smoother at the sacrifice of the highs and mids (slightly quieter), while the velour+cotton has more impact without lowering the highs and mids. The 1000's also handle distortion better than the velour+cotton, meaning that the distortion is less audible than the velours are, making it a bit more tolerable when blasting your ears. I apologize for anybody out there looking for the beyer gel pads to do the GBH-1000 mod.
Update: Come to find out the pads needed to be positioned correctly to sound good.

Update 2: Disregard my edit. I was talking about my older GBH-1000. The differences between GBH-1000 v1 and v2 is that v1's sound is more vieled because of the velour earpads. v2 is better than v1 in every aspect. After getting used to the gel, they seem to disappear on your head after you wear them for a couple minutes.

This is my final version guys. I'm tired of playing around with these headphones now. After re-soldering the headphone cable a few times, burning a part of my gel earpads, and many curse words, I have completed my little mod, and I'm very satisfied with the sound now.

Good luck The main thing to be concerned about his the cabling inside the headphone. Be REALLY careful to not snap the cabling out of the solder joints on the pcb. I've done it a couple times trying to put this thing together, and it led to hours of agony.

 

In the future, I'll remove the white paper stuff that covers the backside of the driver. I'm thinking that it should improve the bass quantity even more because the vents will be less restrictive on the sound.

No, I'm using the DT250 foam discs.

That's what i used. If you have that wide packing tape, you'll have to use some scissors to cut them so that it's not as wide. This is because it will be taped on the driver itself if you don't, and it's easier to fold it around the plastic. Plus, If I didn't wrap them around like I did, I wouldn't be able to tuck in some cotton underneath it.

 

The main reason why I did it like that is because the pads were too big, and I didn't want to use something like double sided tape to put them on there. I wanted to make this mod as reversible as possible, and that's why I'm wondering whether I should remove that white paper stuff behind the driver or not.

 

What I did first was cut me off a piece of tape, wrap it around the circumference of the earpad (leave a little bit of room where your skin meets the earpad so the tape doesn't touch your skin). Then, you get a pair of scissors and cut the tape so that it will neatly fold underneath without covering anything. Just make sure that you have the screws hanging in the holes underneath the earpad before screwing it in. It makes it a ton easier, so you don't have to play around trying to put in the screws with the earpads installed.

 

Feel free to take a look at the pictures on the OP.

 

As far as the recable making it sound better, It will probably make the signal a bit cleaner, but it's nothing to spend $300+ over. Imo, it's more of a placebo effect than anything else.

Try it out. I don't feel like removing my tape, and I don't have any of those bracelets lying around. 

 

The main bad thing that I can see with that setup is that the bracelet would wedge itself so far into the groove that it would only secure a small part of the earpad. Plus, if force is used (ie. cotton underneath), they may pop out. Using glue may help, but I don't know if it would actually seal the gaps so sound won't leak out.

I was considering that when I first got the pads, but I thought that there wouldn't be a good seal around the earpads. Velcro doesn't seal very well, and the sound would leak out. One of the easiest ways to secure the earpads would be to get some double sided tape that's has a circumference a couple inches smaller than the circumference of the headphone, and put the earpads on then. The downside to that, though, is that you can't put any cotton between it, and if you wanted to remove the double sided tape it would remove some of the white felt material along with it.  

 

Another way would be to hot glue the headphone where the bottom of the earpad rests (around the speaker). That would be an easier method than the double sided tape I mentioned earlier, but it may have a chance of damaging the earpads when trying to remove them. Plus, you wouldn't be able to put cotton underneath the earpads if you put in double sided tape or hot-glued the base of the earpads to the headphone. 

 

Another method I thought of was to use hot glue in the grooves where the earpad's lips go at, but it wouldn't necessarily be reversible, and it may damage the earpads if I ever needed to remove them. If you know that you're probably not going to be removing the pads anytime in the future, then this will be the preferred method because you don't have to mess with any screws or tape. It will also provide a better seal than the method I'm using right now, and it will probably look less tacky. You can really put cotton underneath it too (I think I'm obsessed with cotton).

I changed the material from cotton to toilet paper. Come to find out, the toilet paper sounds a bit more transparent than the cotton, and it's easier to manage. With the cotton underneath the pads, it kept on wedging out until the cotton covered a portion of the grill. This seems to fix it while adding subtle sonic improvements.
