Sennheiser HD660 (I have an old version) are great headphones that can be plugged into a regular 3.5mm output and you can enjoy great sound. They just have a great sound signature that is suitable for most genres of music. I like them better than the HD600 and HD650. But my HD540s give me a...

Unfortunately, what you see here is a custom headphone. I had Reference I and Reference Gold, in which I broke the wiring on one of the drivers. So I decided to make my Reference I 600Ohm with the buffle and felt pads from the Gold. The standard Reference I buffle has a stiffer material and does...

Thanks for the advice! Yes, I tested the headphones without any foam at all and I hear even more high frequencies. I tried to restore all the foam as I imagine it to be judging by the way it disintegrated and the way it was in the Gold headphones. I have a dense acoustic fabric on the back and...

Hi Trollchu. I sometimes use my HD540 ref I with a tube OTL amplifier, which is a high-quality copy (not a Chinese one) of the Darkvoice 336 with unused soviet tubes that was once unboxed for the first time. This amplifier gives you more sound compression (imagine that you're pressing the...

Thank you very much for your answer! I will order a pair to try. I don't use foam in front of the drivers at all - only a very thin cloth. To my ears, anything that covers the center of the driver kills all the magic of the sound.

Can someone give me a link to these wang_yifei pads? I seem to have bought them from this seller, but they turned out to be thick, bigger than the diameter of the headphone cups and sounded terrible. Maybe I ordered something wrong? In my opinion, pads cannot be made of leatherette, but only of...

I tried pads with DT990 and in my opinion they don't fit and make the sound like with closed headphones, adding bass, but reducing the level of midrange. All the magic of the HD540 sound is lost. But I am now using these pads from 990, but completely redesigned. In my opinion, the inside of the...

I just bought this thing on Amazon. It softens this pad and fits perfectly. Highly recommend. My headband is clean, but it's very hard and unpleasant to the touch.

Thank you all for your advice. It seems like I've made a deal to buy a driver. One more question. Can anyone take photos of the velor pads on the Gold from both sides, which are quite rare? It was mentioned earlier in this thread that they sound the best. Is it possible to somehow repeat their...

Hello, friends. When I was doing the service, I broke this thin wire near the HD540 Gold driver. And when I tried to solder at the very base of it, I made it even worse, until I broke it to zero. During the assembly, the engineers put the wires between the felt screen and the foam for some...

Thank you all for your advice! Mine seems to have transparent plastic on the inside. But I can't understand why the sound is so deaf. There is a lot of bass and very detailed highs (the highest range). But there is something missing between the midrange and the treble. It sounds as if there is a...

Thank you for your reply Plieb! I bought them from audiosanctuary.co.uk and these are definitely official pads. But different countries may have a slightly different stock in stores.

Guys, please help me to find original thick pads for HD660. I've already bought original pads, paid about £35, and these pads wear out after just a few weeks. One side gets smaller than the other, they get softer. For that price, I expected something of higher quality. I know that the original...

I've been experimenting with my 540 II headphones for a long time now. And I also tried inserting a disc the same size as the baffle without covering the speaker itself. The driver itself was completely open. To my ears, this adds to the midrange but reduces the clarity of the sound. Am I right...

Thanks for the link! Bought 100mm for £0.59. Do you think they will be the same?
