Excellent foam tips offering comfort, good isolation and great value for money
Great Company! Really attentive to customers. They're able to offer tips comparable to Comply (Users know the deal here - Comply tips have great isolation but tend to basically disintegrate pretty quickly, which is always a disappointment because they are overpriced to begin with!) I was happy to see Sonicfoam offering a variety of options to fit most IEMs and found the fit and isolation to be on par with the best I've tried. Comfort is key and these certainly delivered on that front. I was able to get a great seal and isolation too, so of course sound quality is simply all the more enjoyable for that. You get 10 pairs! That is really good. Enough said. I particularly like foam tips because isolation is better and they tend to improve the response of almost any IEM for me, especially those with a tendency towards shouty upper mids or clinical and unforgiving treble. I don't suffer as much from ear fatigue when using these. Was very happy to potter about yesterday for hours with super comfortable fit and great immersive sound. An ungodly amount of tea was had and all seemed well with the world (my tiny world anyway). Tested with various CD to Hi Res quality tracks (various artists - R.E.M to Boards of Canada to Porcupine Tree to Kate Bush to Opeth to Mark Knopfler to Megadeth to Pink Floyd to Elliot Smith to Tears for Fears to Steven Wilson to Shed Seven to Deftones to Sheryl Crow!?! - and many more. Using: LZ A7 - Audiosense DT200 - Moondrop Aria + Fiio Q11 DAC Comfortable - Good isolation - Good quality - Great Sound. What's not to like 👍

Exceptional Fit and Noise Isolation—A Must-Have Upgrade
Did not fit my Fender IEM but fits my daughter’s IEM. They’ve completely transformed my daughter’s listening experience. The packaging is neat and professional, with a storage case that keeps everything organized—great for switching sizes or keeping spares handy. The foam tips themselves are soft yet durable, offering a snug fit that stays comfortable even during long sessions. Noise isolation is noticeably better than standard silicone tips, making music and calls clearer and more immersive. They pair perfectly with my daughter’s in-ear headphones and don’t slip out. The customer service (Amy) is also phenomenal. tried to reach to them and she immediately responded and answered my questions. Thanks so much!

I recently upgraded to the SONICFOAM Memory Foam Earbud Tips, and they have truly transformed my listening experience! Here’s why these tips deserve a full five stars: Comfort and Fit: The memory foam material is incredibly comfortable, molding perfectly to the shape of my ears. They provide a snug fit that stays in place, even during intense workouts or long listening sessions. No more constant adjustments or worries about them falling out!

These tips effectively block out ambient noise, making them perfect for both noisy environments and quiet relaxation. Sound Quality: The improvement in sound quality is noticeable. The foam tips create a tight seal that enhances the bass and clarity of my earbuds. Everything sounds richer and more detailed, taking my audio experience to a new level.

Good quality memory foam tips that enhance the sound of your buds
These are very good quality memory foam tips and I think a reasonable price for the number you get. I like the fact that you get one size, as opposed to the usual small medium and large, where you end up throwing two thirds of the tips in the bin. The sizing guide is good and worked for me. The foam tips give good isolation, especially in windy environments, and gave excellent passive noise reduction. As with the original foam tips, I found the sound enhanced with a better fit with these foam tips, over the usual rubber tips which I have also tried. I will order these again when I have worked through this batch, which I expect to take quite some time. Customer service is also good, my tips arrived with what seemed a hand written note asking me to check the fit and let them know if it was OK.

Great for sound isolation but overestimated the size for my inner ears
I found a seperate review here that helpfully included a sizing guide for when your IEMs are not on the list in my case Liunsoul TANGZU Wan'er S.G. The SF1s fit perfectly. The first couple of days they've been great but the last couple of days I've had some sort of cold/sinus infection and the inflamation in ears is just a bit too much for these, leading me to the conclusion I should have picked the Medium. Personally would have preferred a mix pack. I get the idea is to give you a years supply in one box but as a first time buyer the option for a selection would have been helpful. Easy enough to share the other sizes out when they do not fit. Appreciate its impossible to tell you what size you need for your ears I just went with the logic that I typically also go with the largest tips provided when I get new buds and that has generally worked out well, it is evident when I put these side by side with what I replaced them with there is an appreciable difference in size and because of the foam consturction much more dense hence the irrtation being experienced. They appear to be incredibly well constructed, the foam quality is very good, squished a pair between my finger and thumb and they reformed their shape pretty quickly. My buds dont have an app to test seal quality etc but I can confirm to me background is fully drowned out as sound comes through the buds. Simply a 4 because of my own personal issues.

Noticeable upgrade for Bowers & Wilkins Pi7 S2
I was sceptical but thought I'd give these a try, as I'm always fiddling for an exact fit when wearing my B&W Pi7 S2 buds. I love the buds by the way, the sound is brilliant but, with the original silicone ear tips I find they are prone to move on my ear, so I lose the bass and upper mods when this happens. Anyway, I ordered the Sonic foam SF1 size M. Never used foam tops before so they feel a bit different. Not uncomfortable, just different. Easy to get used to. Boy do these things stay in place. So good...and the seal they provide is excellent. It really improves the bass and overall richness of the sound. Not only that, but due to the superior seal, the noise cancelling is drastically improved. Massive difference when I'm out walking and a car goes past. Highly highly recommended. These tips are a fabulous upgrade and help bring out the best in my prized B&W buds.

Finally, foam tips that don’t cause intense itching!
I am using these for my Moondrop Aria 2, these are so amazing. I was one of the people who had no luck with the usual memory foam tips, and now I think I have found the perfect pair! I have tried all sorts of memory foam eartips, those caused unbearable ithcing. With these ones, that's not the case. I have had nothing but comfort with these. These are squishy, soft and amazingly comfortable. The softness alone makes me love them a lot. If you were to go to any other memory foam brand, they would be hard haha. These ones are the softest I have tried. In terms of sound changes, they give better bass response on the whole, the bass roll off is slightly better compared to Moondrop factory tips, and these give for a more natural sound. Tips overall can affect sound, and these ones by far make them sound the best. These were also easy to install to the IEM iteself, and easy to put into the ears. By prepping the tip first, you allow for smooth insert of the IEMs. They also stay in the ears very well, given how soft they are, I was expecting an easy and secure fit in the ear, which exceeded my expectations. These are compatiable with my Moonndrop Aria 2 model, and they fit very well in the ears. I think these are amazing. In terms of overall comfort and quality 10/10. Thank you for this product.

Excellent sound isolation
I’ve generally used silicone tips for my Jabra Elite 4 Active earbuds but have found that those do not necessarily block outside noise as they are not always a snug fit in the ear. As I use my earbuds mostly on journeys on public transport, there can be significant outside noise from the bus or train as well as those annoying travellers who have to share their music, loud comedy clips and telephone calls with everybody else! I chose these Sonicfoam tips as the listing and many reviews indicated that they provide excellent sound isolation. The memory foam flexes to fit the ear more snugly that the silicone types that I have used previously. They are comfortable to wear and don’t slip out easily when I’m on the move. Importantly they fit the charging case of my earbuds perfectly although that will obviously vary according to the type of earbuds you have. Although earbuds aren’t generally as good at blocking ambient noise as over-ear headphones, the combination of these tips and the noise-cancelling of my Jabra earbuds is quite effective at reducing outside noise. These tips are definitely an improvement on other silicone tips I have tried. The sound quality is pretty good although in quiet environments I do find that the silicone tips that I used previously do offer slightly better sound, particularly having stronger bass. But in noisy environments such as bus or train they are a big improvement. One feature of the Amazon listing for these tips that is particularly impressive is the detailed listings of various brands of earbud showing which of the five Sonicfoam models is suitable for each. Each of the models comes in a choice of three different sizes so I initially bought a pack with all three sizes to ensure the best fit. They are delivered in a protective plastic box and are easy to fit. Overall, I’m very pleased with these tips and definitely recommend them if you’re struggling to keep outside noise from spoiling your listening experience. One downside is that in my experience the sound quality isn’t quite as good as silicone tips in quiet settings. These memory foam tips also don’t last as long as silicone ones, with the listing stating four weeks per pair. But those issues aside I think these are a very good product for keeping out background noise.
