Comply 500 Core Series | Memory Foam Replacement IEM Ear Tips for KZ, Moondro...

I have used the medium size foam plugs on my Sennheiser IE8 earphones and they fit just right as I had expected. Sennheiser for some ridiculous reason, does NOT make MEDIUM size foam ear buds for their earphones which come with their IE series. I even confirmed this with Sennheiser and the customer service agent agreed that, for such an expensive pair of earphones, it is not logical not to have a medium size earbud in foam. Foam insulates the best against ambient (outside) noise so it was a pleasant surprise that the T-500's were very effective, as effective as the Sennheiser foams, in blocking out the sound of the metro (subway), even when I listened to classical music. You don't hear people speaking and they are as effective as the Sennheiser HD-25 series closed headphones in noise suppression. As for the sound quality that some mention regarding the dullness, I don't feel it at all. You may need to increase the high frequencies using an equalizer but the bass is great and the brightness of the sound, mids and highs is very good - just as good as the Sennheiser foam. The material being softer, makes it much more comfortable while still giving an excellent seal around your ear to block out noise. The differences in the hardness of this Comply foam and that of the Sennheiser stock ones can explain the little adjustment required in increasing the highs a bit, but after this, the sound quality is great. I have a pair of Paradigm Studio 20 high-definition speakers and so my listening is quite well trained and attuned to hearing different frequencies. The most important thing is the excellent noise isolation and the comfort, which the Comply T-500s do an excellent job of providing. I would highly recommend the Comply T-500s.

Genuinely required if you want the best audio profile you can get. Coming from an audiophile, if you want to get your money's worth out of the IEMs these attach to, you'll need these. The foam is super comfortable and comes in a variety of sizes to fit your ears best. I ended up using a medium and a large size tip and they fit great. Best way to use them was to crush down the foam then insert them into my ears where they'd fill up, almost like earplugs. The tips' foam quality must be premium because they seal super well in my ears. They also don't degrade easy so they should last you as long as your IEMs do. Highly worth the money, definitely purchase it if you want the best IEM experience.

I used to be an avid runner, running 6 - 12 miles a day with these things. After I stopped running so much I used this sometimes in the gym. They are great, they do hold in against sweat and provide some level of noise reduction. I have the JayBird BlueBuds X bluetooth headset and these work nicely with the headset. The small tips didn't fit well on my ears, the large tips were too big for me, but the medium were just right as I am able to wear them for an hour with little to no discomfort. The other sizes were uncomfortable. It took a little bit of work to get the tips on the headset, but once they are on they will not come off. Make sure you are gentle when putting them on your device. After about a month of use one of the medium tips ripped and became unusable but the other one was intact. Not sure if this was due to wear and tear on my end, just a defective piece, or if I didn't put the tip on properly. It was just odd because the other tip was still in great condition. I recently bought another set of tips only medium size. I would give this product a 5/5 but because one of the tips ripped I am taking a star off. I also think they are a little pricey for the materials involved. I would buy this if you aren't sure what size you need.

I've seen several reviews for these tips that say they do not fit the Jaybirds earbuds. Comply may have changed the material because mine were a stretchy material that I was able to stretch over my Jaybirds, which wouldn't have been possible with a plastic tip that some reviewers said theirs had. It was NOT easy to get these on, I will say that. They certainly don't feel like they're intended to fit the Jaybirds, but with a little work, they went on, and I can't tell any difference now. They work much better than the tips that came with the Jaybird. I've had problems for as long as I can remember with earbuds falling out of my ears, and it drove me nuts. With these tips, not only did my Jaybirds stay sealed in my ears for hours without any needed adjustment or loss of bass/sound quality, but they never bothered my ears. A lot of noise-canceling earbuds make my ear canals feel raw after a half hour or so, but these never bothered me once during a two-hour ride. As far as sizing goes, the small tips were definitely way too small to fit on the Jaybirds, and I don't think they would've fit my ears well anyway. It seems like that size is intended more for children. On the opposite spectrum, the larges seemed way too big. The medium was the perfect fit, and I feel like they would fit 90% of people.

If you’re highly sensitive to noise for falling asleep, like me, you have to give these a try. I’ve tried everything under the sun, even custom molded earplugs from an audiologist and yet playing white noise through my headphones with these specific memory foam earbuds are what made for the perfect sound proof combo. I live along a major freeway and I sleep peacefully through the night even with cars driving by fast and traffic noise! Amazing! Would recommend to anyone looking for sound proofing!

they work okay, fit decent, memory foam did feel comfortable but had had one ripped.

I just recently picked up a pair of Jaybird Bluebuds X but was dismayed to find that the stock tips that came with the headphones kept falling out of my ears and didn't fit quite right, thus I was wasn't too impressed with the sound quality. I knew they weren't sealing properly and I wasn't getting the full experience; I was worried I'd have to return them which would've been extremely disappointing, but after reading some reviews of the Comply tips I decided to give them a try before throwing in the towel. All I can say is "HOLY BASS, BATMAN!" I mean these are bluetooth earbuds so they're not going to compare to a wired set, this is to be expected, but these Comply tips have really made these Jaybirds shine! Anyone that reviews them as not fitting the Bluebuds X isn't trying enough, it takes a bit of pressure but not too much, they look like they won't fit but there's a bit of give at the core and they fit snugly on the male portion of the earbuds. Very, VERY satisfied with the purchase. Will update after some time passes, but I'm thrilled.

Great noise cancellation
