Comply 500 Core Series | Memory Foam Replacement IEM Ear Tips for KZ, Moondrop, FiiO Sennheiser & More | Superior Noise Isolation, Ultimate Comfort, Secure Fit | Black, Large (3 Pairs)

First off, I love these earphone tips! I've been using my first set for 3 weeks now. I have these on my Jaybird Bluebuds X earbuds - and yes, they do fit. You're going to read a lot of negative reviews on here about how the center of the earphone tip is too small for the Jaybird earbuds. If you hold the foam tip next to the jaybird ear piece, why yes, you've made a correct observation. The foam tips input center IS smaller than the jaybird earphone piece. Why wouldn't it be? I want to make sure these tips are secure on my headphones. I mean, come on, you just spent $135 on a pair of headphones... do you really want your headphones wobbling around in your ear and have it fall out and hit the ground? You want it to be a firm hold to prevent that scenario. Yes when you install these foam tips onto your device, you'll need to have firm squeeze on the piece, and as you push, twist the earphone tip and it'll glide right on (with little effort). Now that we have gotten that taken care of, lets talk about the quality of this product. Its exactly whats pictured. 3 pack of black isolation earphone tips. The material its made of I would describe as very similar to foam ear plugs that you would use for swimming, shooting guns, or sleeping. I'm your average male. I purchased the large earphone tip for one reason, its expandable foam. Even if it was too large, at least its expanding foam. But this isnt the case. These are the perfect size for my ears and I would say that I have your average size of ear canal. Large tips will compress really small, for easy insertion into the ear canal, then slowly the foam will expand molding to your inner ear. Works great! All in all, I'm very happy with this purchase. The isolation earphone tip really helps drown out outside noise and deepen the bass as well as make the treble more crisp.

I was honestly surprised how big of a difference these made. Super easy to install, they fit perfectly, and the memory foam is noticeably more comfortable than the stock tips. Seal is great, sound feels fuller, and they stay in even during long sessions. No ear fatigue at all. If your earbuds don’t feel quite right, this is the upgrade you didn’t know you needed.

. I won't say that these are completely flawless, but they're the best I've seen so far. Once in a while one of the companies will furnish earbud pieces that actually stay in, and seal well. (Strangely, my last pair of buds with excellent ear-piece fittings were a cheap Sony version I picked up in the city on discount --I have never since encountered a better fit, even in Sennheiser, Koss, you name it.) These foam tips make up for it all. They work great. My only issue is that if you exercise they occasionally need to be pulled out and reseated. Not sure if it is body temperature change or something else. Adjusting will not do. You need to actually (and very simply) pull them out and reseat them, and the fit returns immediately. The pack comes with three sets of tips. I am still working on my first set. Do not be alarmed when the tips seem to become misshapen, which is normal. I believe someone else here mentioned a way to clean them. I have not had to do that yet. I figure that if the three sets of tips give me a full year or more of use (changing them every four months or so), then they are well worth the bucks.

I use these for my IEM’s. The fit is just right for me, they don't fall out of my ears at unfortunate times while on stage. My only issue was the 3.5 day delay in delivery. Can’t seem to understand why it took so it was delayed so many times. So, if you like a really nice replacement foam for your IEM’s, these are the best I’ve found. But on the other hand, order before you need them, as there seems to be a delay in having them delivered on time.

The comply 500 foam fits really well in ears, and are easy to put in, but don't seem like they'll last long. I've only been using them for a couple of weeks and they're already tearing. The foam is soft and easy to clean, but I really don't think they're going to last long at all.

Got these for the sound core sleep a20's. You have to work a bit to get them on, but they do fit and the sound isolation is well worth the effort. They are a night and day difference to the supplied tips. In addition to the superior sound isolation they also provide a much better fit and comfort. Would highly recommend these to anyone looking for improved noise isolation, fit, and comfort.

I have ordered these twice now. The first package lasted over five years. They are comfortable and create a good seal.

I bought these after reading that a lot of people enjoy using foam vs silicone tips on their IEM's. I wasn't expecting a huge difference or anything, but I was hopeful. After popping them on my KZ Castor's, I'm absurdly impressed. They are extremely comfortable, the sound isolation is superb, and the bass is improved. Win, win, win. I heard they wear out and eventually tear, but that's just the nature of the material. That said, I'll keep buying these. They f'ing rock man.
