SF2 Small - Memory Foam Earbud Tips - 10 Pairs - Black

WOW! I put these on my KZ ZS10 Pro 2’s and the bass was astonishing!!!! I thought the bass was pretty good already, but now it’s amazing! They fit great and are pleasantly comfortable. These tips isolate outside noise very effectively! Just be sure you check the charts to get the right size for your buds. Great value as well. Enjoy!

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.

Pics show them on my Shure 425s. I will also use them on 535s. I have used Comply (expensive and to me too soft/not durable), and a variety of other tips. These rate at the top for balance of comfort, quality and fit. Fit on the earphone is great. Not too hard to get on, but firmly in place once they are. They are shorter than Comply ones. And similar length than most. Most important, they still get in my canal plenty to isolate. But if you have a crazy deep canal and are familiar with tips know that these are not extra long. Quality. Time will tell but first impressions are very good. They are soft, but not so soft they tear. (A problem I’ve had with others). The skin of the foam is less porous than other lower price point ones. Which in my experience will help them last more than a few sessions. I’ve put these tips on and taken off a few times sitting here. They seem more durable than others. Comfort. To me they are great. Definitely firmer than some but not in a negative way. They return to shape well in ear, and seal with no discomfort or too much pressure on canal. Sound is not effected. I’m sure due to the great sizing they have figured out. Isolation is comparable to Comply, which based on price is the “premium” product. These do compare. Bonus- these shipped in a convenient compartmented case. Not anything expensive but useful (I’ve tried all sorts of storage in past and I like this best). So the seller gets a nod for the thought. Not a negative but if the seller had these same quality in Red and Blue they would be perfect. Or Red and Black. On stage it’s easier to know which ear on quick glance with different colored tips. Just an idea. Overall I will buy these again and recommend to others.

I was willing to give a 5 star review based on the level of customer service and on the product itself. If these had a perfect fit for me it surely would be 5 stars. That will be subjective to each person. The profile could be a little less tall so the earphones sit deeper in the ear canal. The value is worth the upgrade as long as you receive a second set via their customer service team after submitting a review to them. Ear comfort after an eight hour shift is greatly improved over the OEM tips. Sound quality is also greatly increased. I can hear the bass that was missing before the upgraded tips were installed. As a bonus they block out more of the ambient noise as well. It is highly likely I seek out SonicFoam for continued tip needs. They turned my $25 earbuds into my preferred set over my $150 earbuds. The foam quality seems good but could be softer. Easy to install and the foam helps hold the earbuds in place. Durability is TBD. Take a look at the prrovided pictures to see the difference between the OEM and the SonicFoam. Edited for durability... I've been using the same set for 20 days. 8+ hours most days including on my 3.5 mile walks. They also traveled with me on a roundtrip 5 hour flight. They performed well on the plane and are still holding up like new. I recommend these.

These SF2s fit perfectly on my old Jaybird Freedoms and Monster TurbinePros. I looked a long time to find compatible replacements that fit correctly and was really pleased to find these. The foam is very soft and comfortable in my ear, provides excellent noise cancellation, and allows me to enjoy the fantastic sound quality of these two earbuds again. I’ve tried silicone and foam, and vastly prefer the material used in these because they conform so well to the anatomy of my ears, which silicone just cannot replicate. Also, excellent communication and customer service from the people at Sonicfoam. At about $1.50 per pair, I’m all in on these.

Finally found foam ear tips that fit my KZ ZS10 Pro X earphones without being loose around the headphone tip or inside my ear. I have large ear canals so these foam tips expand comfortably isolating external sounds giving my music a deeper bass sound than the original silicon tips, and no itch!. Best of all? the price, they're not as expensive as other brands. They also fit the JBL Vibe Beams, same fit and audio bass improvement, but just as all other earbud tips for these Bluetooth with a case, they don't fit properly, I have to remove them from the earbud so the lid closes properly to charge. Highly recommended.

So the good stuff first.... These earbuds are great, they fit my ear and fit on practically any earbud I throw at them. They feel great and they rarely ever fall out. Literally the only time they fall out is when I wear them to bed, which I totally get if I'm switching sides and everything. So now the bad.... This entire pack of earbud tips will last me 3 months. The dumb part about it is that their major flaw I feel like can be easily fixed, because these earbuds are 2 pieces put together and after about 2-3 weeks they will separate, thus breaking them. If these earbuds were one continuous piece, or if they were welded together with a stronger adhesive or something THESE WOULD BE PERFECT. I would gladly pay 2-3x the price so that I would only have to buy this pack once and I'll be all set for the next 1-2 years or basically until I need to buy another headset. Because of this flaw, yes I'm a repeat customer, but only until I find a better product that doesn't need to be repurchased every 3-4 months. The only saving grace is that these are $15, but a part of me feels like this flaw was an intentional design for this exact purpose.

Review is for SONICFOAM Memory Foam Earbud Tips - Premium Noise Isolation - SF1 Medium size.... I have 2 models of TOZO earbuds....The T12s and the Golden X1's. I like both models, with the Golden X1's of course coming out on top, due to the more premium features. They both come with silicon tips. Not that they are bad of course, but when you want the best out of your earbuds, you need a good seal in your ears, and the silicon tips just don't cut it. That leaves memory foam tips. Originally I ordered the SF4's, thinking that they would work fine since they are small-ish. Nope, too small for my ears, didn't make a good seal, so I emailed Amy on support. She made it right, promptly issued a refund and I ordered the SF4's, which are a little bigger in size. PERFECT FIT! I put them on both the Golden X1's and the T12's. The seal is perfect, which makes the T12's block out most noise...much better than the silicon tips. The Golden X1's are on another level, with excellent ANC. I found that the silicon tips just didn't provide the best sound or ANC...but with these on both pairs....So good. I do really think the bass response is much better with these instead of the silicon tips. I won't switch back anytime soon. Highly recommended if fit and sound is important to you. As far as the charging case goes....The T12's charge right away, no adjustment needed, the Golden X1's, the case is a little shallow, so you DO need to push the earbuds down to make contact with the charger contacts, but once you do, it will charge just fine, so close the case and you are good. I did NOT need to remove the tips to charge, but you could do that as well, but then...you know...wear and tear on the tips...not good, and will wear out faster. I use the X1's daily. Well done SONICFOAM!

Il est très rare que je laisse des avis mais je me dois d'en laisser un sur ces embouts d'une qualité et confort exceptionnels. J'ai quelques modèles d'IEM dont des KZ ZS10 Pro 2 qui m'étaient très inconfortables, j'avais mal aux oreilles, j'ai failli les retourner mais j'ai préferé commander ces embouts. Je ne regrette absolument pas cet achat, j'en oublie même que je porte des IEM, l'isolation sonore est parfaite et on obtient des basses profondes. Le seul petit bémol est qu'il est assez difficile de mettre les embouts sur les IEM mais une fois que c'est fait on en parle plus et c'est que du plaisir !

Tiennent bien sur les écouteurs et rentre dans la la boîte.

They wear off after a month or so, gladly they are 10 pairs. Wish they would last longer and give seal like the original Sony WF-1000XM4 tips.

He comprado estos tips para auriculares B&W pi8, sennheiser momentum tw4 y beoplay ex. Se ajustan a la perfección (gracias a las indicaciones y compatibilidad de diámetros de distintas marcas de auriculares, de gran ayuda). Gran mejora de cancelación de ruido exterior, con la obtención de un mejor sonido. Sonicfoam ofrece la posibilidad de compartir tu experiencia. Inclui, hubiera pedido tamaño pequeño x el mediano. He inmediatamente me rembolsaron el importe de la compra. Excelente servicio al cliente.

Essas são as piores espumas que já comprei, não consegui usar pois só de colocar elas no fone elas já rasgaram. Horríveis, super frágeis, rasgam só de colocar a mão.
