Installation in general is a bit tricky but that’s just a design thing. The product itself is great.

These did not fit. I sent them back and ordered directly from Senhauser. The part that should slide into the slot around earpiece was a bit too wide and therefore would not go into place and seemed so tight and small.

Pads are too thick and the lip would not go into the groove. Tried everything and they would not install correctly so I trashed them.

These replacement earpads were compatible with my Sennheiser HD450BT headset. I like them better than the OEM earpads because these are stitched unlike the ones that came on the headset originally which fell apart because it looked like the pieces were glued together. I'm hoping because the pieces are sewn together and not glued they will last longer than the original which fell apart in a year of light use. The foam is comparable and is comfortable on the ears. The earpads slip onto the plates of the headset which is a little tricky but it has nothing to do with the earpads and more the design of the actual headset itself. Once the earpads are on they aren't falling off.

These are great, but impossible to install. At least four hands are needed to replace the originals.

These replacement pad are, in my opinion, identical to the original ones. I had one starting to tear. I don’t know if there are install instructions somewhere, but they weren’t with the pads. My suggestion is pick a starting point and take your time. It may seem difficult, but it eventually starts to fit in the groove.

Good product, I would say it is a little bit pricey, but when you check the quality, and the comfiness you forget about. Anyways it is the only other option I found aside from having to buy a new pair of headsets.
