HD4.50 Ear Pads Replacement Compatible with Sennheiser HD 4.40 HD 4.50 HD 4.40BT HD 4.50 BT HD 4.50 SE Headset Earpads Ear Cushions Upgraded Protein Leather Memory Foam Black

Softer, more comfortable, better isolation, and sound signature is largely unchanged with the exception of a small enhancement to the sub-bass, which these headphones need (they don't dig that deep with the stock pads). The material is also far better than the cheap stock PU. It's a nice protein (imitation) leather that looks and feels close to genuine sheepskin.

Fitted my senheiser 4.40 perfectly and look very similar to the originals

I've tried a few Brainwavz pads on the HD4.40BT but they killed all the bass. These don't wrap around my ears like those did, but they at least provide full coverage of my big Dumbo ears, and therefore better isolation than stock. Sonically, there are a few surprising improvements. Low bass is beefed way up, sonic image is wider, mids are much clearer, and that peaky upper midrange is tamed a little bit, compared to stock. I always worry about losing that magical musical coherence that makes Sennheiser cans so great, but these retain most if not all of it - I can hear more instrument separation, which is good, and I still find myself wanting to listen to them any chance I get. They are incredibly cushy and comfortable, and I thought the stock pads were actually pretty good in that regard. My only complaint is that they seem a little less snug or stable on my head, but tightening the band a notch mostly fixed it. These will not magically turn the HD4.40BT into a true "over-ear" headphone if you have big ears, but if you don't mind soft pads sitting on your outer ears, I'd recommend them. The stock sound signature is probably more "correct" but if you want to use these on the subway the extra bass and isolation is worth it.

The earpads on my headphones started to split. So, I replaced them with these. To install, keep one side in place with one hand while you stretch with the other. It takes some finesse. They are comfortable with more ear room, I don't notice too much downside from the reduced insulation. They are also lighter. I recommend them.

I bought those for my 3 years old Sennheiser HD 4.40 headphones after the original Ear Pads started pealing off. The ear pads are not exactly the same shaped as the original (they are slightly more square shaped, while the originals are slightly more oval shaped), but they do fit nicely and look very good. The comfort is on pair or slightly better than the original. Installation is not easy (it's same as with other Ear Pads replacement), but it is manageable if you are persistent. As for the quality, I expect it would last the same as the original.

I have Sennheiser 450bt headphones which I replaced the earpads with these. Huge difference in comfort. It can now be considered over-ear headphones.

Difficult to install. Durable and an acoustic upgrade, fits the aesthetic of the headphones.

Installation is not quite as easy because it is quite tight to fit into the headphones, but it does offer some stretching so it does have/need maneuvering around. Other than that, its very quality and comfortable.

Ottimi padiglioni, sicuramente meglio degli originali (che tra laltro, giusto x dire, dopo qualche mese di utilizzo si sono spellati come la pellicola bianca interna delluovo sodo). La "famosa" Sennheiser nn fa' una bella figura, questo prodotto che le sostituisce invece sì

it's well on the headphones, but it is not for large ears. They are the same as the originals.

Parfait pour remplacer les coussinets d'origine sur un casque Sennheiser HD 4.5

Ibought these because the original pads on my HD 4.50 BTNC had started to wear out (the seams were coming loose). The pads are bit thicker and larger than the original earpads, but that makes them a more comfortable fit around the ear. Well worth it. If I had known these to be so much better, I would have replaced the originals a lot sooner.

Product received looks nothing like product in photo. Product received is a softer knockoff of original cushions, not the bigger cushions ordered.
