The rubber tips that came with my Jabra Elite Active 75t earbuds never stayed in place very long, which let outside noises in and made music sound bad. This product solved all my problems and fit perfectly and comfortably. As noted in their Compatibility List, they don't fit well in the Jabra charging case, but if you compress the tips a bit and hold them in there a few seconds, they're fine.

Perfect fit for Shure, ADV Audio, and similar IEM with a small speaker opening of 3.3mm. These are a great fit at 3mm. Memory foam is soft and aids sound quality. A much better option for longer listening than denser foam. Best option for the quality, price, and quantity. Plus the case they come in is really convenient. Great care in packaging.

I use a few Shure SE 215’s for my band and we like to change the foam tips very often. I was hesitant to buy something other than Shure brand foam tips, but after giving these a try I will continue to buy Sonicfoam tips. The price is great, quality is great, they create a tight seal, and even think they feel better inside my ear. The only reason I’m giving it 4 stars is because it doesn’t come with a filter like the Shure brand. The filter helps with debris, ear wax etc. It is not a big deal if you clean your earphones regularly.

After selecting the size (s,m,l) select SonicFoam model S3. You can also verify the model used for any type of earbud from the sizing chart provided at the SonicFoam website.

I recently purchased the Sonicfoam SF3 mediums to try on my ISOtunes Sport Caliber BT earbuds, and I am very happy with them. They fit onto the earbuds perfectly, block sound well, and are very comfortable. The earbuds even fit in the charging case with them on. Before this, I was using the ISOtunes small, short foam plugs, because the ISOtunes mediums fit my ears very tight, and would get uncomfortable after long periods of time. The Sonicfoam mediums are a little larger, but they are also softer. As a result, they seem to fill my ear canal a little better, than the ISOtunes small size but, they are more comfortable than the medium ISOtunes plugs, which are a little bit harder foam. Update: I recently ordered another pack of these, this time I. Size SF2 medium. These fit the Axil XCOR earbuds perfectly, and the XCOR fit into the charging case with these on also. I am very pleased with these plugs.

I bought these because of the great reviews and the price per set. The reviews are true. They feel like good quality foam earbud tips. I like how soft and comfortable they are. They spring back relatively quickly. I did buy these with the purpose of trying to have them as tips for Otto Noize Barrier Micro Hearing Protection buds. These unfortunately aren't the correct length, but do fit on the stems. I will keep em just in case since I'm sure they work, even if just slightly short. Took one for the team for those of us competition shooters looking for alternatives lol.
