Wow! Sennheiser HD 540 Reference are so good. - Page 46

post #676 of 757

Hairspray, I do agree that velour earpads seem to make the sound more shallow if you have the wrong type which I believe I do.  I do feel that HD 540s do require a specific dac/amp combo.  I feel like either Burr Brown (maybe Texas Instruments) or AKM dacs seem to produce a more enjoyable sound for me when using HD 540s.

Did I tell you that 540I 600ohm is better than 300ohm?

 

Sennheiser had made a lot of 540s,

and 540 is not the best vintage Sennheiser,it's one of the best

no need to rush

This is another auction to look at: http://www.ebay.de/itm/Sennheiser-HD-530-/221472207806

 

Until someone can prove wrong the impressions that the HD 530 (not II) sounds like the HD 540, I don't see much point paying two, three, four or x times as much for the HD 540.

I went back to the Ref II today after just using the Ref I for a while. First impression was that it didn't sound as good but it's because of the flattened velour pads I put on them. Looks like I'm going to have to get either HD430 or HD560 foam, transplant it into the old skin then learn a proper suture and knot technique with needle and black thread to stitch it back up.

HD430 pads are here for my Ref II. They clip into the Ref II with no issues but now the Ref II sounds bloody terrible... =( Congested, a loss of sonic resolution and transparency. The difference is very significant as far as I'm concerned. Hopefully they've got some good foam inside them that I can use in my velour skins. If not, I'm stuffed.

Unfortunately, the grey foams inside the HD430 pads are just as flimsy as the yellow original foams I removed from all my velour pads. Admittedly these new foams are fresh with no odour but they don't give the greater ear-to-driver distance that I was hoping for. HD560 foams are the same grey material but are thicker so give the extra distance required. HD560 pads are £30 a pair though, double the price! =/ Just great... Am I really going to have to resort to using a different kind of material? I have a lot of spendings riding on this.

I recently got a pair of hd 560 earpads because i'm a velour fan.  I noticed that they are certainly thicker than the previous velour earpads that I had for my hd 540s.  Feels like the struggle continues for the right parts. :(

I have several velour skins that have been gutted of their foam. I was looking online for a source of foam but there is so much expense for any fancy solutions. Then it hit me... Cheap yellow supermarket sponges for cleaning... Perfect! =D I could buy two circular metal templates used for shaping round cookies, each for the inner and outer earpad dimensions that I need to cut out... This could actually work!

 

So I could shape the cleaning sponges into appropriate doughnut shapes with sharp round circles, clean the earpad skins in warm soapy water, leave to dry, combine, then sew up with a suture kit. Only cheap way of doing it... I've had enough of buying earpads from Sennheiser spares just to get them for foam.

DIY seems like the way to go, can't blame you. Let us know how the progress goes, should be interesting.

I have acquired a set of 540G, and is looking for information regarding earpad replacement.

I assume it is impossible to acquire original leather earpad already, but please proof me wrong, I'll kiss you for that biggrin.gif:D

The seller showed me the earpad replacement that he is using right now, it is a HD250II compatible as stated, I try to search the part number 032952 in the Senn accessories but no luck:
http://en-us.sennheiser.com/accessories

This is what it looks like:
CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), quality = 80
CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), quality = 80

Can someone show me the link and description of this replacement earpad? or is there even better replacement that I should consider?

Cleaning sponges are only soft when they're wet (or at least damp). When they're dry, they get hard. No way they'll be suitable replacements for earpad foams.

 

If you plan to DIY earpads, why not just buy a bulk piece of furniture grade foam rubber and cut it yourself. See www.buyfoam.com, for example, where you can get a large piece for a couple of bucks. Or you can walk in to a home furnishing store (e.g. Home Goods) and buy a chair cushion that you can gut for the foam.

The small yellow sponge that I cut up yesterday was actually too flimsy and compresses too easily. It is 20mm thick but squashes almost exactly like the foams I originally took out. Same material characteristics, I'm just looking for something a little firmer but a tad less firm than the HD560 pad foam. With the HD540II, I feel the sound is best when it can radiate out through the foam relatively unhindered but where it is rigid enough to support the drivers with a bit of distance from the ear. I'll find something. Just gotta clean the skins thoroughly, prepare a template for cutting the foam then decide on a suitable foam source to cut. I have about eight pairs of skins that require replacement foam then the headphones should sound good enough to sell.

Mum and Dad got me some cheap pastry cutters today. Against the HD560 foam shown, the 10cm and 7cm (I think) diameter cutters are suitable size for making the foam pieces I would need. I would push the cutter down and use a sharp blade to cut around it. Just looking for a foam that isn't too thin/thick and isn't too firm/flimsy. The foam needs to allow a significant amount of sound leakage too IMO.

Finished sewing up a pair of HD540II velour pads containing new HD560 foam. I had previously held them together with staples whilst I tested them. Pads are soft but firm. The black colour of the velour skin has faded a bit with use/age and my cleaning. Looks nothing special but now the HD540II sounds great IMO. I put thin cloth over the driver cover, laid a thin foam circle over that then clipped the earpads in. Looks quite tidy now.
