Gvoears Replacement Earpads for Sennheiser HD650/HD600/HD660S/HD545/HD525/HD535 Headphones, Ear Pads Cushions Also Compatiable with Massdrop X HD6XX/HD58X and HD580/HD565 Jubilee Headphones(Velour)

Got them for a pair of 58x. Installing was simple enough, just squeeze them in there and push in with your fingertips (slide them under the pad and push the plastic down and make sure not to squeeze the outter grill of the headphone).The inner diameter of the pad itself is a little smaller than the stock pads.Very fluffy and comfortable.Did not alter sound at all to my ears.I do not use the inner protective foam.Price is great. Good to have as a backup also.

Fit HD565 Ovation just fine, easy to install. Not sure as to durability. Comfortable, don't impact audio performance. Like that the inner foam ovals are included.

I got these for my five-year-old Massdrop Sennheiser HD 6XX cans. Installation was breezy and the pads are firmly attached to their new mate. I can't hear (or feel, these are quite comfy) a discernable difference between these and stock pads, which ain't bad given that OEM pads cost up to four times as much.They also include replacement foam interior liner pads for directly above the drivers, which is quite nice.

ordered for my HD600. easy to install. same comfort as the stock pads. came with the inner foam screens(?) as well. as expected, the overall sound changed a little. with the previous pads (almost 15 yo) very loose and worn out, the overall sound had become very bright. the new pads made the overall sound a bit darker/veiled but i know it'll change gradually as the pads start wearing out again over the years.

There is an extruded oval plastic ring on the inside of the replacement pads and an oval indent on the inside of the Sennheiser HD 650 headphone ear cup. The original earpads have a deeper oval, the replacement earpads have a shallower oval and one side is deeper than the other because they are badly machined. There is supposed to be a click when you pop the pad into the headphones with almost no effort - no extra pressure is required, but the best you can do with these replacements is pressure fit them, and there is nothing holding them in as a result. They will fall out.They are also constructed of denser foam and put pressure points on my ears and cheeks. There is an interior foam slip that goes between the pad and the ear cup, the replacement slip is denser than the Sennheiser one and will likely affect audio quality, but I don't know by how much.The advertising shows a prominent pair of HD 650s - if these were machined and received proper Q&A maybe they would fit, but they absolutely do not.My personal opinion: I bought my headsets 6 years ago and I've used them for hours a day ever since then. That's quite a return on investment. I just bought replacement earpads and headband from Sennheiser themselves because it's cheaper on their website. If I get another 6 years of comfort out of them for $50 then why would I compromise on something I use every day of my life?

i don't I liking that sound change.

I have Massdrop HD 58x, and after 3 years of use, my OEM earpads started to tear away revealing itchy foam. I ordered these because I didn't want to shell out $50 for the official Sennheiser replacements. They aren't quite the same, but they're pretty comfy and don't compromise the sound. They seem a little better in terms of construction vs the OEMs. I recommend as the OEMs are far too pricey, and the quality is pretty much on par or lesser than these.

I have ordered replacement Sennheiser pads from other brands before and they could never seem to get the material, look, feel and height correct, this one is different. The Velour looks and feels identical to the Velour used by Sennheiser. These pads are almost identical in height as well to the newer Sennheiser pads they are now using on HD600s and HD660s's. I own both of these headphones with under 2 hours of usage on each so they are practically new. The only visual difference I can see is the material on the lower inside of the pads are slightly higher then stock but they sound identical to me to stock. These also come with the foam inserts for each earpad so you don't need to purchase separately. The only issue I had is that the thickness of the plastic snap-in ring is slightly thicker than stock making installation a little more difficult. On stock pads I can push on the padding in the corners to lock in the pad, on these, following directions from the manufacturer, I needed to push fairly hard on the INSIDES of the pads around the ring to get it to snap in. They are secure in there but it was a bit of a pain compared to stock. For the price compared to OEM these are a total bargain. Time will tell on durability, but I do not see anything that would indicate that they will not hold up. Definitely recommended.
