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!

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.

For me, these memory foam earbud tips are the only way I can truly use my AirPods Pro effectively and comfortably. The standard silicone tips just never provided a secure enough fit, but these memory foam tips are a game-changer. They create an incredibly snug fit in my ears, allowing me to run, jump, or do whatever I need to without ever worrying about them falling out – total peace of mind! They also last a surprisingly long time given daily use. I have had to replace them a couple of times over the years because the foam eventually separates from the inner core. I suspect this is primarily due to my own habits, specifically the way I tend to twist them into my ears and the amount of sweating they endure during workouts. Given how much I rely on them, it's a small trade-off. The price is great for the comfort and security they provide, making them an excellent value. I also really appreciate that they include three different sizes in the pack, which ensures you can find the perfect fit for your specific ear shape. If you struggle with your AirPods Pro staying in, or just want significantly better comfort and passive noise isolation, these memory foam tips are an absolute must-have. I can't recommend them enough!

I’ve been using the SONICFOAM Memory Foam Earbud Tips (Medium, Black) for my AirPods Pro, and they have exceeded my expectations in every way. Comfort: These memory foam tips are incredibly comfortable. They conform perfectly to my ears, providing a snug fit without any discomfort even after prolonged use. Unlike silicone tips, they don’t cause any irritation or pressure. Noise Isolation: The noise isolation is outstanding. Once these tips are in, external noises are significantly reduced, enhancing the overall listening experience. They are perfect for noisy environments like commuting or working in a busy office. Fit: The medium size fits my ears perfectly, and they stay securely in place. I’ve had no issues with them falling out, even during workouts or other physical activities. Sound Quality: The foam tips help to create a better seal, which in turn enhances the sound quality of my AirPods Pro. The bass is more pronounced, and the overall audio experience is richer and more immersive. Durability: The quality of the foam seems top-notch. Despite regular use, they have maintained their shape and integrity. The 10-pack offers great value, ensuring I have replacements ready when needed. Installation: Swapping out the old silicone tips for these was straightforward. They attach securely and haven’t shown any signs of loosening over time. Overall, the SONICFOAM Memory Foam Earbud Tips are a fantastic upgrade for anyone looking to enhance the comfort and sound quality of their AirPods Pro. Highly recommended for anyone seeking premium noise isolation and a superior listening experience.
