Memory foam expands to fill the ear canal for a strong, forgiving seal
See Comply Comfort Plus TSX-200 Memory Fo… on AmazonShort version: Comply TSX-200 memory foam tips are the easiest way to get a strong, comfortable seal with most IEMs. Foam expands to fill the ear canal, which improves bass, isolation and stability. The trade-offs are a shorter life, slightly softened treble and more maintenance than silicone.
Buy them if silicone tips slip, press or never seal properly, or you want maximum isolation for travel. Skip them if silicone already works for you, or you want your IEM’s tuning exactly as designed.

Frequently Asked Questions
Are Comply foam tips worth it?
If silicone tips don't seal or feel comfortable for you, yes. Foam is the most forgiving way to get a good seal and strong isolation. If silicone already works, foam's shorter life may not be worth it.
How long do Comply tips last?
Foam degrades with use, so they need replacing far more often than silicone. Replace them when they stop expanding fully or feel rough.
Do foam tips change the sound?
They can soften treble slightly and usually improve bass by improving the seal. Many listeners like that change; those who want the IEM's exact tuning often prefer silicone.
