Replacement Heaphone Ear Pads Cushions for Sennheiser HD4.50BT HD4.50BTNC HD 4.50SE HD4.40BT HD 400S HD 350BT,Headset Earpads for Sennheiser with Durable Leather and Comfortable Sponge-Black Color

These new ear pads are stitched vs glued, which is why my original ear pad ripped. A little tricky to put on the new ear pad but they will fit on the headphones and feel as good as the original. The fabric between back of the ear pad that touches where the sound comes from on the headphones is a little thinner than originals but I don't think it will matter.

Thank you so much. They are perfect and easy to put on, just slip on one side and rotate it (earned hack).

These feel high quality, and they are a lot easier to install than I was expecting compared to other headphones cups I've replaced before. The instructions from the manufacturer were a lot more helpful than what comes with OEM Sennheiser replacement cups.

Great pads. Installation is fairly easy if you watch the video on the sales page. It took me about 10 minutes to replace the original pads on my BTNC 4.50. The mesh inside is slightly thinner than the original, but the pads are more comfortable. All in all, it was a great buy. Shame on you, Sennheiser, for not providing replacements.

Everyone complains about how hard it is to install these, but......they really aren't that hard and they stay on solidly. Installation for this was so daunting, I put it off for months. Here's the deal, when you pull your old ones off, you'll see that there is a ring of material that slips inside a gap between the speaker guard and the housing of the headphones. On the edge of that material is a black shiny elastic band. It looks impossible, but think of it like a shower cap. Once stretched slightly, it wants to close back in and go into the gap. Position the headphones so that you can access the top part of the earpiece you want to install first. (this is literally the most difficult part of the job) Gently stretch the material and slip a little bit of it over the headphone housing and wiggle it into the gap. Once you get a little bit in there, squeeze that spot to hold it in place and stretch the neighboring parts of the "shower cap" so you can fit them over the housing. That little band on the edge that wants to slip into the gap for you, it's not going to fight you, once the edge gets in the gap, it constricts inward by itself. A couple guitar pics will help you stuff it into the gap to get it started or hold it for you while you work another area. Toothpicks might work, just be careful that nothing cuts or pierces the material. Keep squishing the ear pad down with your holding hand where you've gotten the material in the gap so it doesn't slip out - then work your way all the way around with your other hand. Reach your fingers until the earpad to pull the material out and stretch it over (like a shower cap) and you'll notice it seating itself. Be careful to squeeze the other side so it doesn't pull out on one side while it goes in on the other. When I got to the end (bottom, because starting it at the top of the headphones makes it easier) I used some PC chip pullers to try to hook the material (a crochet hook would work better) to snag the material under the earpad and pull it out. When I did the second one, I skipped the hook and just squeezed the earpad at the top to hold it in place and pulled/stretched the earpad with my fingers to pull it out enough to find the cap. It fell right into place. Once it looks like it might be seated, you can rotate the earpad slightly each way to get it to seat evenly. You'll notice it's on solidly and not about to pull off, even though it looks like a loose fit. Takes about 10 minutes to do the first one, about 3 minutes to do the second one, once you've figured out your technique.
