Sounds very reasonable and good what you are suggesting. I hope I can identify the inner bassport. The big hole on the outside was good as far as I remember. I hope I dont have to buy them again but I would. Will check on sunday when home again.

I think that the tiny hole is more to equalize the pressure on both sides of the driver

You could also have a bad solder joint on the driver, or a spotty connection between the cable and plug on the left cup.

 

Maybe try a different 3.5mm cable first and see if the cable is the issue?

Ok so I found a great non-destructive method for getting a better fit with the alpha pads. You could cut the band an resize them, but with $70 pads I didn't really want to cut them (especially since I go through headphones on a monthly basis and might want to use them on something else).

 

Here's what I did:

 

If you look closely you can see the black band that is going around the cups, right where the pads insert into the groove where you install them. It's a wide black hairband that I picked up at Walgreens for like $2. It provides just the right amount of support to keep the pads from slipping out of the cups and they don't move or slop around at all. You could prolly use a rubber band or something too, but it needs to fit pretty tight around the cups.

 

I'm still baffled by how much better the alpha pads sound than the stock ones. They have a very roomy "out of the head" sound now.

Mine went on tight without any modification and do not slop around at all.  I actually just wish there was a very small air port through the pad somewhere to help bring some of the mid bass and highs back.  I think what happens is with the cups sealed the driver is fighting the pressure to move back and forth as quickly as it would being slightly open.  Ofcourse fully open pads lack bass and are too bright but fully closed seem to err the opposite.  Stock pads still have the most even sound and must be mostly sealed but with a little breathability or not quite as well sealed as the Alpha Dog pads.  Though I have not tried using the Alpha Pads on a real on the road trip which I suspect will add value to the little extra lower end and seal of the Alpha Pads.

 

For careful listening in quiet environments the OEM pads I feel still offer the best response all around, but then again these are not my quiet room close listening cans.

I completely agree with you on the differences in the low end and highs with the alpha pads. I'm not sure if it's that the alpha pads seal more or not. Swapping back and forth between stock and alphas I have a good seal with both and don't feel like the alphas isolate that much more than stock at all. What I was looking for in changing the pads was less low mids and taking some edge off the highs, which is what you want back haha, different ears I guess :)

Thank you for providing feedback and great pictures on these headphones.

I still follow this thread and enjoy all of the mods and comments from all of you.

thanks for the support on my 7520 problems guys. At the moment they are running great so I won't touch them hoping the best ;) But I am looking for a second pair right now. Today my Alpha pads arrived. They were expensive coming from the USA to Germany with customs and transport, let's hope they are worth it.

They will be. The alpha pads bring out the best of the 7520.

pads arrived and put on. first thing I did was putting the fat side of the pads infront. then I saw your pictures and tried it the other way. sounds better I think ;) pads could be tighter for me, just a little bit. before superglueing I want to make sure I don't make a mstake, so one dummy-question: where the pads are fattest, I put a tiny incision into the outer band that holds the pads. I superglue the to layers over each other and it still fits into the opening of the 7520? I don't wanna mess the pads up, they are too expensive ;)

 

comfort is great btw, but the look big on the head now. this will catch some attention I guess when used outside which I intend to do. but this is okay for me if I get a super sounding comfy headphone in exchange.

You actually don't have to make an incision to install the alpha pads on. Some members have found that they don't need to do so, which is fine if it works. I move around a lot, so I just did so to create a tighter seal. I took a chance in creating a small incision at the fattest end of the alpha pads, then over-lapped the folds by about 3mm over each other. They are very very very comfortable and who cares what you will look like with these on, the sound over-justifies that.

 

If you really want to up the ante, buy this: http://www.amazon.com/Replacement-Leatherette-Universal-Sennheiser-Beyerdynamic/dp/B00862522A

 

It brings the comfort of this great-sounding, light-weight headphone to yet another level.

def no need for me to cut the skirt and super glue them smaller but i did notice the inside diameter of the Alpha Pads cutout is actually smaller then the outside diameter of the slots they seat inside.  i can see perhaps cutting a mm or 2 from the entire circumference of the alpha pads skirt to allow them to seat properly around the lip of the headphone. currently the skirt bulges out from the headphone more then the pads themselves do.  This makes them look bigger then they are I feel trimming the skirt diameter a bit might make them look like a better fit.

I recently trade in my Denon AHD2000 that was in mint condition using Amazon. I originally brought the AHD2000 on Amazon. I got more in the trade-in than I paid 5 years ago! Never like the D2000 at all.

I like my 7520 very much with its great clarity and great dynamic range capacity without compression. I wonder if you have any suggestions in headphones that would complement along with the 7520 that I could look at? The Senns HD8 has a interesting build quality. Some like the HP50 but the rated power is 30mW the lowest I ever seen. Any ideas?

I've owned the D2000 and currently own the HD8. Agree with you on the D2000's. HD8's are great for dj headphones, built like a tank, but so are the 7520 even though it doesn't fold. I think the HP is sub-par to the 7520. I did alot of research between them before buying the 7520. HD8's are a nice addition to your collection if you need a sturdy headphone for edm, gassy type music. It does sub-bass nicely, sounds great for a dj headphone, comes with a lot of accessories.

I like sturdy headphones that last more than two years. Another headphone I got rid of was the Shure 940.  I use TLC on them but the headband broke and I glue it all together. It never stopped creaking everywhere and the treble started to distort. It went to the trash instead.  My 7520 never creak on me and the treble was very smooth without the edgiest. My only nitpick on the 7520 is the cups are a bit small but not causing any issue with me. The longest lasting pair of headphones I had was the Beyers for 15 years, a model long gone from the catalog. The driver finally quit on me. The only reason the driver gave out was that one of my vacuum tubes arc over. That was something I do not wish to happen to anyone.
