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

These transformed a set of IEMs I could barely tolerate into something genuinely comfortable. The foam seals well, stays secure, and makes longer listening sessions far easier.

These are like a must buy once you get new earphones. So I've been using these for probably over 6-months and I can't tell you how comfortable these are. Usually regular conventional ear-tips that come with earphones are trash and wouldn't stay in your ear no matter the size you use. That's when Comply shows up with these nice premium foam ear-tips that stay contours to your ear hole, and will stay so well you can go jogging and still they wouldn't come off. In terms of comfort, they're super comfortable unless you get a size too large, so there may be trial and error. They also do a lot better then silicone tips in noise isolation since they contour to your ear, blocking off any space. Installation will take a lot of twisting as the plastic core is stiff, but that's good so they wouldn't fall off. In terms of waterproof, they would become really mushy and kind of smelly, so try not to get it too wet. They will recover though, so don't worry too much. One downfall however, is that they look kind of ugly, but subjective to others. I've been using 1 of the 3 sets for the past 6+ months with my JayBird Blubuds X, and its still running well. Definitely a great buy!

I love Comply foam tips! I use them on Sennheiser ie80 earbuds. To me, they provide more isolation and better sound quality. I've been using these tips for years. They are comfortable and stay in ears better than other foam tips. The only problem I have with these tips is that they last for about three months if you constantly use them. They're not exactly cheap and it can be pricey when you have to keep replacing them. I've tried other cheaper alternatives and unfortunately they do not work as well. I guess you are paying for quality but I do wish they were a little cheaper!! I've also tried their other slightly more expensive version "Comfort Plus" and I prefer these more. You have to be very careful in removing them because they do tear easily. But if you have no trouble splurging, these foam tips really do make a difference!

Fits well. No slippage, even when jogging.

I use these on my Technics EAH-AZ100. Don't let the missing alignment tab or that the tip isn't completely round on the AZ100 slow you down. I was using the largest tips that came with the buds and the seal wasn't firm enough. Medium foam tips fit great in my ear canals and the case. They give a firm, almost grippy seal that brings the technics up to par with even my Moondrop Blessing 3 IEMs.

My Airpods were always notoriously falling out of my ear during my workouts, but these foam ear tips will keep them in for the entire workout. You just have to replace them ever few months, because they do wear out or begin to smell over time. Find the right size and buy a couple.

Slightly improved sound quality due to better fit and definitely helped with cutting out noise! You just need to push them good until the plastic is flush with the metal part. Otherwise it sounds a little less loud

I was thinking about buying another 3 pairs of these but reading other reviews I see I am not alone in my experience, so this time I am going to pass. Last year I bought the S/M/L version in order to try them all and be able to get a good fit. Little I know I was buying disposable earbuds. I used them in my Jaybird BlueBuds X and for sure they are much better than the stock tips. They had a very snug fit with my earphones but having read previous reviews I was expecting this and was able to fit them without any big difficulty. Sadly, the first pair (Medium) lasted about 4 months, using them about 4 times a week (only about 64 use cycles!) and the next pair (Large) did even worse lasting about 2.5 months with the same usage (I assume because of their bigger size - I had to squeeze them harder). The last pair was too small for my ears and kept popping out. Pros: Comfortable Very secure fit Outstanding isolation Cons: Durability is not worth the cost in my opinion Not easy to clean Advice: If you are willing to pay 15 bucks for small and disposable pieces of foam, then read the other reviews and try to figure out your size, so you can get 3 disposable pairs with a combined 10-12 months of durability. In my opinion if you use your earphones to run or do high intensity training (or anything that involves lots of movement) and your current tips keep falling off, the fit they provide might be worth the cost. As for myself I will stick with my almost decent stock rubber tips for the gym.
