SONICFOAM(SF2 Medium Black) Replacement Memory Foam Earbud Tips for Earbuds with Speaker Diameter 4.4-5.7mm - 20 Pack / 10 Pairs

I am a purchasing consumer posting an honest review of the SF2-MEDIUM which I bought. I use the SF2-MEDIUM with my JBL T110. I receive a second set SF0-SMALL for providing user feedback. I use the SF0-SMALL on my Truthear Zero Red.[1/26/25]Easy 5 stars. I would not hesitate to buy these again.I bought the SF2 size in Medium for my JBLT110. Fit is perfect, they slide on firmly and do not fall off. Sound isolation is improved considerably. They feel like foam-roll hearing protection earplugs.They have much less "suction cup / vacuum" feel on my eardrums.The JBLT110 with factory silicone tips have a very pronounced 5~7 db treble boost above ~6K, that honestly sounds like nails on chalkboard to my ears. These sonicfoam tips help to tame that treble boost for an overall better sonic presentation.I am not new to in-ear monitors and foam roll type ear-tips. My first set of IEMs was a Sure E2C 15+ years ago and I have owned various models from various brands since.... Jays, Sony, Truth ear...etc. What's nice about these Sonicfoam tips is the foam expands slowly in my ears, so I can take my time inserting them. Its NOT like a beat the clock... quick before they re-expand kind of thing.[1/28/25]I received a second set as a favor for providing user feedback. This second set is a SF0-SMALL for my TruthEar Zero Red. The Zero Red is well known for having a HUGE sound output tube, almost 7mm diameter. The SF2 tip inside diameter is way too small. The SF0 fits the Zero Red perfectly. Not too tight and not too loose. They are very similar to the OEM foam tips, except the Soncfoam material expands much slower so I do not have to hurry/rush to insert them. As far as sonics and comfort go they are an exact match to the OEM foams.[2/20/25]After almost a month these foam-roll tips are still going strong. They do show very slight signs of wear, but nothing significant. They are maybe still a solid 95%, and they seem to have plenty of life remaining. I use the SF2-MED with my JBL T110 EVERY night to fall asleep listening to waves and rain forest sounds. I also use them during the day to listen to music and YT vids. I literally roll around and fall sleep ON THEM every night. No soreness or discomfort of any kind paired with the small JBLs. I have equally positive results with the SF0-SMALL on my Truthear Zero red. Although I don't use those nearly as often as the JBL T110.I will post a follow-up to this review if my opinions change.

This is exactly what I was looking for. A nice comfortable fit. They seal perfectly. Stays in your ear. Very pleasant experience with them in your ear. Makes noise canceling work better with the fitment in your ear. This is exactly what I was looking for. You cannot beat the price for what these things can do. I don’t care that they say they can only last for 4 weeks. You get plenty of them to switch out when they become worn. They come in a nice divided plastic case. It is worth every penny in my opinion for the comfort and sound quality you get. Plus they feel secure and do not fall out. They come with a personalized card asking for feedback and to let them know if you are happy with the fit or not and instructions on changing them and fitting. If they came in orange that would make them perfect!

These are the best foam tips i've ever used.I've done a lot of tip testing in my day (lol) and silicone tips have never worked for me. Other than Final Audio E tips, I dont like a single other kind of silicone tips, and so after getting fed up with that, I tried foam tips. And since then ive tried a lot of different kinds of foam tips as well. From Dekoni and Comply, and a few other brands, but these are easily the best.Firstly, a few things that i appreciated, but dont necessarily effect how I view these eartips. The case is actually pretty good. Another company I bought tips from had a case come with theirs, and it was cheap, flimsy, and broke before I even got it. That doesn't really matter to me but I do really appreciate how good this case is, and it makes me want to buy more just for this tip case. Another is the cute little note they left in the packaging. I've never heard of this company before, I just stumbled across these tips randomly while on Amazon and decided to give them a shot, so I don't know anything about their reputation or really anything to do with their company, but so far as a customer, Its very nice to feel like the person behind the product you have genuinely cares whether you like it or whether it actually benefits you or not.The tips themselves are pretty great. The fit is awsome and one thing that I noticed as soon as I unboxed them was that they are kind of sticky, which is something that I thought I wouldn't like in the beginning but it is actually really nice. One thing I've noticed with other brands, Dekoni specifically, is that the foam that they use might be something that I am actually allergic to, so as they sit in my ear, they tend to itch. These have that sticky coating on them and not only does it help to secure the tips themselves, but It also helps it to not feel like you're sticking a boring piece of foam in your ear. It feels like someone actually tried to make this useable by humans. They also don't sit too deep, which is something that I have found to be an issue with other tips, and I own IEMS that are kind of medium insertion, so these are about the same height of Dekoni bulletz, which I think is a perfect height for them, but they are actually a lot thicker (comparing both small sizes from each company), and I personally think thats a good thing, because I've always thought the jump from small to medium for Dekoni (and a lot of companies for that matter) was too drastic. FIt wise, these are perfect. Couldn't ask for more.One thing of note is that they do change sound a bit. They bring out the bass a bit more, even more so than foam tips already do. However, it's not a ton, and for someone like me that uses EQ, Its a non issue. However, it's just the only potential downside I can think of so far.I do plan on updating this post in the future when I get a bit more time in these tips so I can gauge the durability, but so far, these things are perfect. Hopefully the durability is about the same. I go through a new set of foam tips about every 4 months when I used Deknoi Bulletz as my main tip of choice, so I'm curious to see how these compare in terms of longevity. Even then, they come in packs of 20 for $15, not packs of 3 for $15 like Dekoni does.As of 8/3/2023, these are fantastic and I think I can finally stop tip rolling and I can just finally daily drive a comfy set of IEMs.
