Apple’s silicone tips are fine. They’re "okay." But for a lot of us, "okay" means your $250 earbuds are slowly sliding out of your ear canal while you’re just trying to walk to the grocery store. It’s annoying. You’re constantly poking at your ears, ruining the acoustic seal, and honestly, it makes the Active Noise Cancellation (ANC) feel way less impressive than it should be.
The fix isn't a software update or buying the next generation of hardware. It’s a $20 swap. Switching to foam tips for AirPods Pro changes the entire experience because memory foam doesn't behave like slippery medical-grade silicone. It expands. It grips. It creates a seal that actually stays put when you’re sweating or talking.
If you've ever felt like your AirPods Pro just don't "lock in," you aren't alone. Thousands of users on r/AirPods and MacRumors forums have been complaining about the "soapy" feel of the stock tips since 2019. Silicone is easy to clean, sure, but it has zero friction. Memory foam, on the other hand, uses the heat from your ear canal to soften and mold itself to your specific anatomy. It’s a custom fit without the $1,000 price tag of professional IEMs (In-Ear Monitors).
The science of why foam tips for AirPods Pro actually sound better
Most people think tips are just about comfort. That's a mistake. The tip is the final stage of the acoustic chamber. If that seal isn't perfect, your sub-bass frequencies—the stuff that makes music feel "full"—literally leak out of your ear before you can hear them. This is basic physics.
When you use high-quality foam tips for AirPods Pro, like the ones from Comply or Dekoni Audio, you're creating a much denser barrier than a thin flap of silicone can provide. Comply, for instance, uses a proprietary polyurethane foam that is dozens of times more porous than silicone. This doesn't just block out the hum of a jet engine; it creates a pressurized environment for the driver to work in. You'll notice the low-end feels tighter. Not louder, necessarily, but more "defined."
There is a trade-off, though. Let's be real: foam absorbs stuff. Silicone reflects sound waves, which can make the high-end frequencies (treble) sound a bit "crisper" or "airier." Some audiophiles argue that foam "darkens" the sound signature by absorbing those tiny high-frequency vibrations. To most people? You won't notice. What you will notice is that the Transparency Mode still works perfectly because companies like CharJenPro have engineered their foam with integrated wax guards that don't muffle the external microphones.
Comfort is subjective but stability is a fact
Have you ever done the "Apple Ear Tip Fit Test" in your settings and gotten the dreaded yellow "Adjust or Try a Different Ear Tip" message? It’s frustrating. Sometimes your ears are just between sizes. Apple gives you Small, Medium, and Large (and XS on the Gen 2), but human ears aren't standardized.
Foam is the equalizer. Because it compresses down to a tiny size and then expands, it fills the gaps that a static silicone shape can't touch. This is huge for runners. If you’re hitting the pavement, the repetitive impact usually jars silicone tips loose. Foam creates a "tackiness" that holds the bud in place even when you're dripping sweat.

What to look for when you're shopping
Don't just buy the cheapest ones on Amazon. There are a lot of "no-name" brands that use cheap craft foam. It’s scratchy. It falls apart in a week. Look for these specific features:
- Integrated Plastic Brackets: Real foam tips for AirPods Pro must have the hard plastic "click-on" attachment. If they don't, they won't stay on the earbud.
- Wax Guards: This is a tiny mesh screen. Earwax is the enemy of AirPods. If your foam tip doesn't have a guard, that gunk goes straight into the speaker mesh of the AirPod itself. Good luck cleaning that.
- Charging Case Compatibility: The tips shouldn't be so big that the lid won't close. Brands like Sonicfoam and Comply (the 2.0 version) are specifically sized to fit inside the MagSafe case without issues.
The "Gross" Factor: Maintenance and Longevity
Here is the honest truth that most reviewers won't tell you: foam tips are a consumable product. You can't buy one pair and expect them to last two years. Silicone lasts forever because you can just wipe it off with a damp cloth. Foam is a sponge. It absorbs ear oils, sweat, and dead skin cells.
Eventually, the foam loses its "rebound." It gets stiff or starts to flake. Most heavy users find they need to replace their foam tips for AirPods Pro every 3 to 4 months. If you’re a clean freak, this might bother you. You can't really wash them with soap and water either, as that breaks down the chemical structure of the memory foam. You just have to swap them out.
Is the cost worth it? If it stops your $250 earbuds from falling onto the subway tracks, absolutely. Most packs come with three pairs, so a single $25 purchase usually covers you for an entire year.
The installation trick most people miss
You don't just shove foam tips into your ear. If you do that, they'll feel just as loose as silicone. You have to "prep" them.
- Pinch the foam: Roll the tip between your thumb and forefinger until it's compressed and skinny.
- Pull your ear back: Use your opposite hand to pull the top of your ear up and back. This straightens the ear canal.
- Insert and hold: Put the AirPod in and hold it for about 10-15 seconds.
- The expansion: You will literally feel the foam warming up and expanding to fill every nook and cranny.
Once you do this, the noise cancellation becomes significantly more effective. The "hiss" of the world disappears because you've added physical isolation to the digital cancellation. It's a two-layer defense.
Acknowledging the downsides
Look, foam isn't for everyone. Some people find the "full" feeling in their ear canal to be claustrophobic. It creates more "bone conduction" noise—meaning you might hear your own footsteps or your own voice sounding deeper (the occlusion effect).
Also, if you have very oily skin, foam is going to degrade fast. Like, really fast. You'll see the foam start to lose its matte finish and get a bit shiny. That’s the signal that it’s time to toss them. If you hate the idea of a "subscription" for ear tips, stick with the stock silicone ones and maybe try a "wing" attachment instead.
But for the rest of us—the people who are tired of catching an AirPod mid-fall or who want to actually hear the bass line in a crowded gym—foam is the only real answer. It turns a "gadget" into a piece of high-end audio gear that actually fits your body.
Next Steps for Better Audio
Start by checking your current fit. Run the Ear Tip Fit Test in your iPhone's Bluetooth settings under the AirPods Pro menu. If you get anything less than a "Good Seal" on both ears, or if you feel physical fatigue after 30 minutes of wearing them, it's time to switch. Grab a multi-size "starter pack" from a reputable brand like Comply or CharJenPro. This lets you test whether you’re actually a Medium or if you need a Small in one ear and a Large in the other—which is way more common than you’d think. Once you find your size, you can buy "refill" packs of just that specific size. Replace them the moment the foam feels brittle or fails to bounce back after a squeeze.
