Just wanted to say that I did something similar, and it seems to have worked very well.

Rather than using silicone spray, I used a tub of lithium grease.
From checking around online, most people don't recommend spray-on lubricants for anything, unless it's your only option. I think there are additional chemicals required to make it a spray, and it seems that the lubricants don't last nearly as long.

From reading around, Nerf enthusiasts and RC Car enthusiasts both seem to recommend lithium grease as one of the best lubricants to use on plastic parts, as it's long lasting, and should not react with it.
Apparently some silicone sprays do not react well with certain plastics.

I just used a toothpick to fill in all the gaps in the hinge, worked it in, and cleaned off the excess before reassembling the headphones.

Unfortunately, most full size headphones look similarly huge if you have a shaved head. (not that I like how the NAD headphones look)
I have a large head, and the 7520 look similar, though not as bad. Most headphones are designed so that the band sits off your head like that, but you don't notice it if you have a full head of hair.

They can be annoying when they get twisted and wrap themselves into knots, but they're really good if you have to move around with them on, and the do a good job preventing microphonics.

I was actually wondering if anyone had found a good non-microphonic cable for the 7520. The stock cable is good if anything hits the coiled section, but there's 2ft of straight cord where it goes into the headphone which I've found to be problematic if it rubs against your clothing.

I wonder if Vaseline will work as well. Or do you guys think that'll react with plastic? I'm noticing a slight amount of creakiness returning, so that silicone spray is certainly not a permanent solution.

Just another question, I know I've asked this before, but today the shielding of the cable on my Shure SE530 IEM cracked so I don't expect these to last much longer, so I'm looking for a replacement.

 

My budget is up to about 200 bucks for a pair of IEMs. I like the Sony 7520 sound, so I'd like something a bit similar sounding, neutralish but with still plenty of bass (I usually use IEMs when commuting on the train/bus, etc.) and perhaps a bit more soundstage.

 

What would you guys recommend? Someone already recommended the Dunu DN-1000 here, but those aren't available here in the Netherlands. Any other recommendations? Oh, and I'm looking for a universal fit, don't want to deal with custom-fit IEMs.

 

Thanks!

I think you should give the SE535 a shot,  if you purchased the SE530 from an authorized dealer. Shure has a great out of warranty program and I think you can get in under $200. I think the bass on the SE535 is fantastic. You might also like the UM3X, but you'll have to pick one up used at that price.

I bought the SE530 from some UK reseller who then shipped it to the Netherlands, it was the cheapest I could find at the time and I really don't know anymore who that reseller was, so I can forgo that option I guess :) The Shure sound is nice, but at the same time I've been listening to that for almost 5 years now, I wonder what else there is (I mean, I now know the sound of the 7520, but as far as IEM sound goes I've only really heard the SE530).

 

But thanks though :)

Maybe check out the Vsconic VC1000. Under $200 is actually a tough price point. You get a lot of competition from below with the RE-400, which is a great all rounder. And yet some of the most technically proficient are $300+. The VC1000 might be a good compromise and comparable to the 7520.

So what would you recommend, outright? Say up to $400? Vsonic isn't sold here in the Netherlands.

It's about $5-10 for a tub of white lithium grease. Use a proper lubricant rather than something like Vaseline. Vaseline is also petroleum-based, which means it's likely to be damaging to plastics.
post #819 of 2340

If I decided to use a lubricant on my 7520 I would use something like  100% Synthetic Oil which is safe for use on plastics. I would use something with a needle applicator like this   http://www.amazon.com/Bottle-Synthetic-Lubricating-Wrist-Watches/dp/B00CM1A6D6/ref=sr_1_6?ie=UTF8&qid=1391201839&sr=8-6&keywords=lubricant+needle

 as an example. That way with a needle applicator I may not have to take the headphone apart. Too much lubricant can be more harmful than too little. Makes sure that the squeaks are not coming from the twist joints on the 7520.

post #820 of 2340

Man, so weird. The creaking doesn't bother me at all. Haha. Just putting this out there so people know it's not everyone having issues. And my 7520 is nearly a year old now.

post #821 of 2340

Yes mine does not and I said if. I find that my other headphones do have some creaking noise like my Shure 940 which has been quite bad and even my HD598 creaks at times.

post #822 of 2340

About the squeaking the best lubricant would be a viscous plastic oil based,

(as other petroleum based lubricant might dissolve plastic over time,Vaseline is also not recommended)

I used a silicon oil called traxxas 50k (50k is the viscosity, 30k would also be find),

 

http://www.ebay.com/bhp/traxxas-differential-oil

 

this lubricant is used to lubricate plastic diff part by RC enthusiast, also widely used by speedcubers to lubricate rubiks cube (that's what I use it for).

Once applied correctly in the cups it will last for very long period...trust me on that.It last on rubiks cube for month doing thousands of aggressive fast solves.

I have a question for you guys,

 

I've been thinking about getting a Chinese Omega headphone wooden stand.

Maybe someone here got one or a similar Sieveking one and can tell me :

 

1. If the pads are too compressed when the phone are resting on it? Is it OK to use it, Won't the pads or headband be affected overtime?

 

2. If you got a chinese one, how do they look, is it clear natural wood or a dark one, cause they sure look sexy on aliexpress ?

This isn't really an answer, but I would go with: Brainwavz Peridot Headphone Stand

Why doesn't the 7520 have just a little less bass?! I'd be a happy man.
