Cushion Ear pads Earpads for Sennheiser PXC 450, 350, PC360, HD 515, 518, 555, 558, 595,598 Headphones (WITH PLASTIC LOCK RING)

These are not as good as the original pads, they are much firmer and aren't as comfortable. However the original ones after 5 years have disintegrated so these are still better than those. The other problem with these is the installation, they obviously are reusing packing with newer product. The instructions clearly state that you need to remove the lockring from the old headphones and install into these. I tried for a while and gave up as it looks like they have a firmer plastic piece inside which appears to be the lockring.Coming to type this review the description states that the lockring is included so they just need to change the sticker on the bag they come in.Assuming that you worked it out, the newer pads are a pain to clip in, I for the life of me can't get them to clip in the whole way around. Part of the pad will always be slightly raised. The pads seem to hold on but it clearly isn't right

I cannot tell the difference between these and the originals. They can be a little difficult to install, though the process is simple, and i found it no more difficult to do than with the original ear pads.There is a youtube video you can watch, and that may help: [...]One difference, the video has you reusing the original lock ring, but these come with one pre-installed.

These earpads were pretty easy to install and they worked fine for a short time. Unfortunately, after using them on a few flights, the outer plastic coating failed. The material degraded and rubbed through at the inside seam and the underlying foam is now deteriorating. The original OEM earpads lasted for years so these are definitely not OEM quality. I'll have to try another brand or pay big $ for the OEM earpads.

Took a couple minutes to figure out how to snap them on, but the ear pads seem to be solidly on now. They aren't as soft and comfortable as the originals, by any means, but they seem to still provide decent noise isolation (again, not quite as good as the originals). For the price, I won't argue. Maybe they'll soften up with time somewhat; the previous ear pads I had were well-worn, to say the least.

Update: after 8 mouths the plastic ring that hold it on ended up becoming bridal and break.they look great and give a little more ear room but they don't go on as easy as the original one's.

great quality. Came with lock rings but I swapped in the ones from my headphones just as an assurance. Feels great on my 3 year old PC350's

Nothing like originals, but not $75 either. Not as soft, don't seal around the ears as well. But, better than having black dust from original after 5 years of use! If I was to repurchase, I would buy originals.
