Crysendo Headphone Cushion Compatible with Sennheiser HD 4.40 BT/HD 4.50 BT/HD 4.50 BTNC Earpads | Protein Leather + Memory Foam | Replacement Headset Ear Cushion Pads 90mm X 80mm (Black)

Easy to install ( because they also provide the video help and a tool) Comfortable and does its job very well. Quality is soft and like actual cushion which came with the original ones. Size is perfect and has a sweat resistant coat. Good price point for such a good product. ( and a sweet note in the pack saying thank you from the team Crysendo- good touch )

Good cushions lasted me 2 years with rough heavy use in the Indian climate. Fitted very well with the Sennheiser HD350BT

Excellent product and fit for my senheiser 4.5.

They look well made and soft. Cusioning also looks okay. Should be fine for an year's usage at least.

Very good cusions and easy to fit.. made my headphones feel new again

Good quality product, little difficult to fit but once done, looks good.

Perfect fit for my EPOS ADAPT 360

At first I almost quit trying to get these to fit. They are quite a bit shorter than the original ones. If you look at the difference, you will conclude that these cushions are not made right. But then I read the other reviews. Some of the steps: - Loosen the edge by pulling at it. As long as you don't put too much effort into it, the product shouldn't tear. - Look at the seam at one end of the cushion. That part goes on the top (look at the original cushions' positioning to confirm). - Stick the top part first. Way easier to do the bottom at last than the top at last. - Fit each side. Leave the bottom for last. If you have long nails, they will come in handy. Or get something that is *NOT POINTY* to help you with the fitting. - At last, put the bottom part in. One of the sides might have come off. Do that again after putting in the bottom part. Repeat the process for the second cushion. You will notice that while the cushions are short, the part you will use to put in has a lot more margin so it will eventually fit. Mind you, not a perfect fit, but it will work. Comfort is okayish, a little less soft and breathable than the original ones. But if you are like me, you just want something to put on your expensive headphones. Getting the original ones will set you back 4k INR. I haven't used this for more than 30 minutes, so can't comment on the durability. Best of luck!
