Review: Great AirPod Upgrade!!! - 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!
Review: 5 stars easy, SF2 & SF0 - 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.

### ⭐⭐⭐⭐⭐ Great sub for the more expensive Comply tips
*by A***E on November 30, 2025*

I am amazed by these Sonicfoam tips. I bought these to replace the Comply 400 series that SoundOff recommends for their sleep earbuds. The Comply don't even get me through two weeks of nightly use before they no longer compress, and the foam is just fluff. For the price, this is just not sustainable for me. I put the Sonicfoam tips on my earbuds right away and tried them on for fit. They fit beautifully with great compression and a nice seat in my ears. I turned the earbuds on and did my usual sound test, which is rubbing my thumb and fingers together near my ears. The noise cancelation was amazing. Just for fun, I switched back to the Comply, a new pair, to compare the two. First off, the Comply don't compress nearly as neatly as the Sonicfoam. This means that the Comply don't get a good seat in my ear. This has been an ongoing issue, and I find myself waking up frequently at night to readjust the earbuds. Secondly, and I was totally blown away by this, the Sonicfoam noise cancelation has to be at least double that of the Comply, comparatively. It was one of those double take moments where I literally couldn't believe what I was hearing. I also can't believe I've been spending $20 on three pair of Comply when the Sonicfoam are out there at 10 pair for $15! The Sonicfoam sit comfortably in my ears while sleeping, and are a perfect replacement for the Comply 400 series. With nightly use during sleep (7-9 hours of constant wear), I'm able to get about 10 days of use before they no longer compress. These will be my new replacement ear tips from now on.
