I don't think it would matter, but I never really tested.

 

Thanks, I was so tempted to try the mod I did it the day after posting my question :D I also did this mod later to a fully burned in pair of HFI-700 (I don't think they sound that sibilant compared to a half-way burned in HFI-780 but still, out of curiosity, did the same mod to them). It doesn't matter which hole is covered, the result is the same.

I just did this on my 300+ hour 780s after I stuck some DT250 velour pads on them -- the bass suffered! Naturally I had to try this mod, and it brought my bass back! But even without the velour pads, I felt like the bass of my 780s had settled down quite a lot after burn-in.
I hope this mod gets more exposure, given the popularity of the Grado hole punch mod.

 

I much prefer pleather over the Beyer velour pads as the change they make is rather too much to sacrifice for their comfort, although some might say they never notice any changes switching to velour (and personally I don't find pleather uncomfortable). If you don't have problem wearing pleather, switching back to the stock pads can make the bass and overall PRaT even better on the 780.

Just for fun I decided to try this mod on my DJ1 Pro and it worked fine. The bass is slightly increased without any loss in clarity and without any noticeable affect to the mids or highs

I'll maybe try the mod if I ever find myself needing more bass. Thanks for the tutorial.

So, yeah, I'm definitely going to be doing this to my Pro 900s when I get home.
I wonder why this mod never popped up in my hours of research in modding Ultrasones...

Sorry for the double post, but this deserves a bump. I just did this mod on my Pro 900s, and the sub bass just bellows now. Wow.

Now the pro 900 can have it's amazing mid bass and as much sub bass as the d5k! L3000.gif

You guys do what you will, but I have sent my Ultrasones in twice to be fixed and both times it was done FO FREE b.c warranty 

post #25 of 68

Dang. That's really unfortunate to have a pair of headphones break twice. 
What happened? 

post #26 of 68

The drivers blew (by themselves actually) and then when they fixed it the left ear stopped working and the right driver was also a bit weak. Been a bad run of luck I've had them so little I'm not even missing them which is sad

post #27 of 68

I really hope they can actually fix them if not they assured me they would replace them...they have been really cool about it but $50 worth of shipping later and no ultrasones i'm not the happiest. You think they would accept a trade in if I wanted to trade up to the edition 8s?

That sounds like something else could have been a factor. I don't know the extent of their RMA process, but if you had a bad wire or port causing a short, that could have lead to the issues. I've voided warranties for the sake of "free" performance more times than I can count. I've volt modded video cards, hacked up cases, drilled holes in headsets, dropped LN2 on CPUs for overclocking runs, fabricated my own heatsinks for computer parts, it's all just good fun. I'm not worried about them breaking. If they do, I'll see how nice Ultrasone are with their warranty. If they refuse, I'll see if I can fix it myself. If not, oh well. I new the risks when I started. 

post #29 of 68

Yeah I think when I sent them in something else went wrong because they came back sounding worse then when they left! Hopefully whatever their RMA process is it works better then it did before lol. I would love to be as bold with my DIY projects as you are with yours, do you know how to solder? if so how did you learn? 

post #30 of 68

Yeah, I know. I just taught myself. All the stuff I mentioned above I did in high school. I worked and didn't have anything to pay for, so I just had cash to blow all the time. But, I started soldering when I was like 13ish when I was into remote control airplanes and cars and such. You can get training PCB kits that are made for teaching how to solder on circuits, if you want to learn. The only way you can is to do it yourself.
