Make budget earbuds feel and sound premium
I've never really liked in-ear earbuds. They bother my ears, they always feel uncomfortable and don't stay in place very well. Even really nice ones like the AirPod Pros. So I almost always use over-ear headphones, and just keep a budget pair of Soundcore A20i's in my bag for when I need them temporarily on the go. A friend recommended that I try foam tips, to see if they work better for me. I tried another brand first, but got rid of them immediately because my earbuds wouldn't fit in their case with those tips installed. Then I checked out these Sonicfoam, because the chart said that the SF4 model would fit in my earbuds case. This is amazing, I wish I had tried them years ago! They make my budget earbuds feel and sound like a premium product. The fit is super stable and secure, even when I'm working out and sweating. Even though my earbuds don't have active noise cancellation, the passive noise blocking of these buds is good enough that I can't hear the background music playing at my gym. It's the first time I've ever experienced "all-day comfort" with a pair of in-ear buds, I forget that I have them in. Customer support seems really strong. The tips came with note, saying to contact them if the fit wasn't good and they'd replace them. Also, I can't promise they'll be doing this forever... but in my case the note said that they'd send me a free box in exchange for an email letting them know how well the tips fit. Not a paid review on Amazon, just direct feedback to them in an email. Sure enough, they had Amazon send me another box a few days later. I've gone from using in-ear buds only once in awhile, to these being my daily driver now. I'll never go back to using plain silicone tips ever again.

Definitely more comfortable and fit better.
I love em, purchased Sept and broke this morning. Wil be buying a set of the size I use. Don't bother trying Google's buds seal calibration it'll fail no matter what. The tips sound awesome regardless. 👍🏼

Work with Soundpeats Air5 Pro
Perfect fit for my Soundpeats Air5 Pro. Unlike the Air5 Pro's silicon tips, they don't slide out of my ears and offer great isolation.

Perfect fit
They fit perfectly on my over the ear pods.

A different kind of earbud tip
Earbud tips have been endlessly frustrating - poor fit, falling out, substandard sound due to inadequate seal. These tips change that. The foam compresses just like the foam used for earplugs. They're also a little grippy so they stay put, even when exercising vigorously. The sound of my $30 earbuds (Tozos) improved ten fold. And this great company will send a free second pack of a different size if the fit isn't quite right. Amy was super helpful personally answering my emails. I'm very satisfied...pleased...enjoying my music at the gym again. Thank you!

Pain to get on to Liberty 4 NCs and to put into your ears
It took 10 minutes just to get them onto my earbuds and it can't be directly put into your ears, you half to squeeze these eartips to be able to put them into your ears and wait for them to expand. I think they may stay in your ears longer than the default eartips. However, the fact they are supposed to only last up to a month isn't great, since now you'd have to keep buying them and dealing with the pain in the butt process with putting the new ones on and to put them into your ears. Worse, they still slip out of your ears if you don't put them in perfectly. This will be updated as needed.

run small
not very memory foam'y wish you could buy trial set in all the variants. had to buy trial set in SF4 even though what i think i want is SF2. that said, the sizes seem really small, so even though the SF4 samples are too small to use, at least the SF2's i order will cross my fingers, hopefully the right size.
