3 Pairs Sennheiser CX300, CX400, CX 500, CX300P, CX500G4ME, CX55 Replacement EarBuds Cushions Ear Tips Gels

A comparison to the original CX300II medium sized earbuds...Quality/build: The quality is on par with the original earbuds (these have not ripped after repeated removal for this comparison). These are "almost" as soft as the original medium sized earbuds (which I still have), but as mentioned they are harder.Fit/Size: The hole for placing on the headphone, is slightly smaller, so hopefully they'll be less likely to fall off. I don't want to use the word "difficult" for placing these on, but it does require a little extra effort, compared to putting the original earbuds on the headphone. As for placing them in your ears... It's the same fit as the originals.Sound: Because perception can be affected by so many things, and if you keeping reading reviews you'll see some say the sound is affected, I'll simply add that If there is a difference, it is minuscule.Feel: Again, these are slightly harder than the originals... I do "think" I can feel a difference between them, but keeping in mind that I've been switching back and forth between the original and the new earbuds, it only takes me 30 seconds or less to forget about any perceived difference, and then simply focus on the audio content.Overall recommendation: I would recommend these earbuds as replacements. Not only is the price low, but these earbuds get the job done.

I lost one of the earbuds to my awesome Sennheiser CX300. When the package arrived i got 10 of the medium buds. The CX300 originally came with 6 buds: 2 small, 2 medium, and 2 large. You think it would be more helpful if they included some smalls and larges in case people used them. I used the smalls so this was a little disappointing. Anyway tried putting them on and they didnt fit. I searched thru my junk drawer to see if i happened to have some of the spare buds and i found them. Upon inspection it appears the original Sennheiser buds are softer and can stretch to fit properly so i put my original mediums on. I will deal with these for a while until i purchase a new set of earbuds. Purchased 8/21/2011 for $4.30 and promptly thrown in trash. :(

I'm going to be brief:These earbuds are not identical in size to the originals but they are the closest I have found so far. They are slightly smaller than the originals but not by much (about 1mm).If you like me have lost one of your earbuds and are looking for a replacement I would recommend this product. They will most likely fit you very well and you'll get a big pile of them for a small amount of money.

I lost one of my medium sized earbuds, and found that the other two sizes (small and large) just didn't work for me. I ordered these replacement tips late on a Sunday night, and received them on Wednesday. Perfect fit on my headphones, and seem comparable in quality to the originals. Would recommend.

When I bought these earbuds it was kind of a gamble because I wanted something for my Blackberry headphones. They are perfect! At first I thought they didn't fit but it was just a tight fit. They get tossed around my purse all day and never fall off the headphones. Which is much more than I can say for the ones that came with the phone! They cancel out the noise as much as my last ones did. Fortunately I will probably never buy more now. But if I did I'd order these again in a second!

I was disappointed with this order for two reasons:1) I needed these earbuds quickly and paid for express shipping, yet it still took four days to arrive. IMHO, this is unacceptable for so-called express shipping. Seller claimed UPS was slow during holiday season. If that's the case, don't use UPS. I paid for 1-2 day shipping, not 4 day shipping.2) These items arrived loose in an envelope. There is nothing to indicate that (a) they are new and (b) that they are actually Sennheiser earbuds as the title of this product claims.With that said, the earbuds work fine. But I would have preferred authentic Sennheiser earbuds delivered within the time frame for which I paid.k

I bought these because for less than the price of replacement ear buds and less than the price of half the number of (assorted size!) tips, I got all the same size and a lot of them, for many pairs of headphones. I didn't think these would work when installing them. They fit alright and I'm not real concerned about them falling off. However, the material is less sturdy than the standard material for most ear buds. That means they aren't great, compared with something that probably would have cost more. Do I regret buying them? Not really, because they cost $4.50 and I got double what I would have had I bought them at Fred Meyer. If they cost a penny more than I paid, I would be upset about it, but I find these adequate. I don't see any sense in returning them. For the price, they meet expectations, but are not of shockingly good quality and I wouldn't necessarily recommend them.

I've ordered these twice now and have been disappointed both times.1st time, they sent large pairs, but at least most of them fit the headphones (CX300). One pair was barely too large in its inner diameter, so they slipped off regularly.I decided to order again, because I like the headphones but need more plugs. This batch came in medium size, but all 3 pairs had the large inner diameter issue. They BARELY don't grip to the headphones, so they regularly get caught in my ear when I take the earbuds out. Very annoying, twice I did not get what I anticipated.
