Great replacement for Sony wf-1000xm4
Bought the Sonicfoam tips based on very positive feedback and so far I'm very impressed. These were bought to replace the tips on my Sony WF-1000XM4, fit and comfort is excellent, I tested on a 4 hour train journey and I found the noise cancelling and sound quality to be at least as good as the Sony tips or possibly even better. Due to the more compliable foam on the Sonicfoam I found them easier to get an airtight seal and once fitted they felt very snug and secure. I ordered the medium and although they are fractionally bigger than the Sony the foam type used compresses more so the fit is spot on. Another point worth noting is that the Sonicfoam have a smooth shiny coating in comparison to the matt finish on the Sony, I think this will make the Sonicfoam easier to wipe clean !......they also fit in the charging case without any problem. If like me you are finding it difficult to obtain Sony replacements and are looking at alternatives, save your time and go for the Sonicfoam, they do the job brilliantly and are great value for money. It's too early to comment on longevity but Sonicfoam say a pair should last for 4-6 weeks, so having 10 pairs in the box I'm covered for at least a year. Thanks Sonicfoam I'm really happy with my choice :)

Buy with confidence
With several companies all selling foam ear tips, it can be a bit daunting working out which company and which product to go for. But I'd recommend giving Sonic Foam a try. Their details, advice and charts helped me to quickly identify which tips would best suit my Sony XBA-H1 earbuds. Impressive, given that these particular buds are over ten years old. Normally I'd test the waters with a sample pack of different sizes, but that's not an option here, so the charts and measurements were a big help. I went for medium sized tips, which arrived very quickly and securely within a plastic case, which conveniently has a slot for each pair, rather than lumping all twenty together. Sonic Foam currently have a promotion whereby if you send them some details of your order, they will send you a second set of your choice for free. The process was hassle-free and the second set arrived equally quickly. The tips were a bit bigger than the silicon ones I was using, so they required a little bit of manipulation to insert snuggly into the ears, but once they were in they felt reasonably secure. (Hint - try moistening them before squeezing them - they'll go in easier.) They don't totally isolate the outside world, but they do dampen down much of the back ground noise. I tried them out on a train full of kids on holiday, and was surprised how much of the racket they had reduced by the time I took them out! Audio-wise they're fine. I found they gave the bass a deeper and richer tone, but I did have to slightly adjust the treble upwards. No big deal really. And the comfort more than compensates for any audio tweaks. Foam tips are a very cost-effective way to listen to your music in a noisy environment, compared to the expense and hassle of recharging noise-cancelling earphones, and I'd recommend going with Sonic Foam for their high quality product and service.

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.

Excellent foam tips
I bought these particular foam tips to use on my Sony WFC700N earbuds, because the included silicone tips are not the greatest. I have previously used Comply foam tips on other earbuds but you only get three pairs per pack, so was I reluctant to buy those again. I noticed these SonicFoam tips were cheaper than the Comply tips AND came in packs of 10 pairs. I thought they would be worth a try at that price. The SonicFoam tips were delivered the next day and came in a plastic box which was a nice extra. Also in the box was instructions in how to use the foam tips, and a message from Amy offering a free exchange if the tips do not fit. There was also a one-time offer for new customers of a free pack of tips if you email a picture of your tips on your earbuds and give feedback. So top marks for customer service and engagement. Fitting the foam tips onto my earbuds was very easy, and the fit and comfort is fantastic. I wore my earbuds for hours and they did not slip out at all and never got uncomfortable. The SonicFoam tips also drastically cut ambient noise. My Sony WFC700N are noise-cancelling earbuds but previously I could still hear a little noise with NC activated. Now with these tips I cannot hear any ambient noise and can only hear the music. Because the seal is perfect, my music now sounds amazing and immersive. I am very impressed with these SonicFoam tips and would not hesitate to recommend them. Five stars.

NOT SONY WF-1000XM5 COMPATIBLE!
Great quality, and they do fit the sony earphones -- but they don't fit into the case! So if you're not willing to put them on and off the earphones every time you use them, they're the wrong choice. I read online that the SF2 Large would fit the WF-1000XM5. My mistake for believing them.

Great upgrade for my Jabra Elite 85T
My opening point is to state that earphone fit and comfort can be so different for each one of us. It can be challenging finding optimum fit. Good luck in your quest for the fit you seek. I bought a set of Jabra Elite 85T in January 2023. The supplied oval silicone tips didn’t work very well for me, even after taking the excellent Myfit option on the Jabra APP. I've had great headphones in the past and even spent money on bespoke silicone moulds to achieve a tight airless fit to maximise the full range of sound my headphones offered. The Jabra silicone ovals start well enough in my ear, but then lose fit, compromising bass and engagement for me. On the 5th of February, I decided to try the sonic foam tips for my 85T’s. 10 pairs were supplied in a 10 compartment plastic box. I have been using these tips almost every day for a couple of months now and and wanted to wait a reasonable time before writing this review. I bought the medium size for the Jabra Elite 85T. I normally use medium to large. I was pretty relaxed about it as Sonicfoam will work hard with you to find your fit, offering a free size change or refund. I was surprised with their determination for customers to be happy with their product. Sonicfoam’s ‘fit’ page recommended no larger than medium to ensure the earphones would fit into the Jabra Elite 85T charging case. They are a good fit for the Jabra 85T case. The case magnets don’t pull them in to the case as readily with the sonic foam tip, but I will sacrifice that feature for great sound in the ear. They are a good fit for the Jabra 85T case. Placing round buds onto oval posts was actually easier than i thought, although, I did soften the them with some low heat on a hairdryer. You don’t need to do this, but I’m glad I did as it was very easy to fit them. To place them into my ear, I rolled them gently between thumb and forefinger compressing the foam and inserted them as normal, waiting for 10 seconds or so, until the foam expanded and secured them in my ear (as instructed on the back of the storage case) I am still using the initial 2 tips (from 10 pairs supplied) after 2 months. This is probably longer than recommended, but they still work perfectly well for me. These foam tips are good value. The depth and clarity of sound achieved was exactly as I had hoped for. Deep bass response, high trebles and everything in between. The buds stay in my ear and maintain fit for me for as long as I need. They even allow me to use them on my Peleton exercise bike without falling out or dropping off whilst working out. The supplied Jabra Elite 85T silicone buds fell out my ear after a few minutes exercising. Some people love this oval silicone tip, but it just didn’t allow the excellent earphone to perform for me. These have become my earbud tip of choice and I will definitely buy them again.

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.

improved comfort and sound! Great customer service!
Well what can I say, I've always used over ears, as I listen to mainly drum & bass, and Trance, as a former DJ. I didnt think the sound could be improved as much as it has with my first pair of IEMs. I had the seiniser ie 100, but hated everything about them, the fit was bad, and the sound tinny. But I wanted a decent pair of in ears for out and about in the summer, (or for running) as I use over ears in the winter. I picked these up for £180, and I can't belive how good they sound just for £80 more than the seinisers,it's like night and day. I really love the planar sound, it's changed my whole music liberally, and I'm hearing sounds in a different way, or that I've never heard before. Like with robert miles tracks the violins really get brought to the front without sacrificing other sounds or bass, with the electronic sublte sounds emphasesized on tracks like Fable. I've customised them to just how I like them, using the silver bullet nosel. I hated the Bullet nossels initially because it sounded so different to what I was used to, But After playing around with them and getting used to them I love the intensity I get with the silver bullet. (Reviews are like marmite with the silver bullet, either love it or hate it). I used the smallest stock silicone tips for comfort and they sounded great, stayed in comfortable, and didn't ache my ears like the larger sizes. My only gripe was that old school drum & bass tracks that relied solely on sub bass could sound weak, but this has been fully addressed and fixed by moving to memory foam tips the next size up in M for that deep tight seal, while still being comfortable. The sound has improved even more. They do take a bit of customisation but I am enjoying my music in a way I have never heard it before, and I'm falling in love all over again. The reviews on YT were OK, but these are so much better than I expected. Especially at the price point. All the upper mids, and background sounds are brought forward and, every sound can be heard separately which I prefere, than the more natraul blend of the flower nossels. I understand some people might like a more natraul sound, or may find the silver nossel a bit hectic, hence why so many love the gold flower nossel, but this is exactly how I like my music to be. I can't imagine it getting much better than this personally for the price.I picked up the foam tips in sizesmall initially and while they did fit great, and increased bass, them mids and background sounds I loved so much from the timeless 2 were the trade off slightly, but this was fixed by moving to a size M for a better seal which sonicfoam provided for free, and boom my old school sub heavy drum & bass now sounds great too. And sound has been improved all round surprisingly 5* to timeless 2, and sonicfoam for the free tips and great customer service! 👏 🎶

Qualité / confort exceptionnels
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 !

Good, could be better
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.

SONICFOAM Earphone Buds - A Worthy Alternative!
I would like to say I'm very pleased with the high quality build of the SONICFOAM earphone buds for a price that significantly betters the higher cost of more widely known varieties. The SONICFOAM buds come in a conveniently sectioned case that 2 bud pairs are contained in, (a nice touch), and after getting used to the new sensation of the buds in my ear canals I really liked the way the memory foam buds remained in place and I was really impressed with the auditory sound isolation, (from external noise), and the much enhanced bass response from my earphones. If taken care of the SONICFOAM earbuds will last many weeks even when used continuously and it is easy to clean them by using a diluted alcohol and water mix such as eyeglass cleaning wipes. A quick once over with a wipe and the bud is clean and sanitised. Water and soap is not the best option as the memory foam tends to loose the ability to be compressed, (and temporarily remain that way when inserting them into your ear). Definitely a recommended product!

Não recomendo
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.
