Comply™ replacement ear tips are softer than silicone, cost-effective, simple to install, and backed by our 100% Guaranteed Fit Program.
- Comply Comfort: Maximize your earbud comfort and eliminate earbud pain caused by silicone tips. Comply foam ear tips are made for all-day comfort. Body-heat activated memory foam adapts and molds to your ear, providing a completely customized fit for hours of comfortable listening.
- Earbuds Stay In Place: Never let your earbuds fall out again. Comply memory foam ear tips are engineered to conform to your ear, providing a better grip than silicone. Whether exercising, working, or going about your day, our replacement tips will keep your earbuds from falling out.
- Block Out Noise: Our heat-activated memory foam expands in your ear, creating a superior seal to reduce distractions and improve noise cancellation for an exceptional audio experience. Elevate your sound at lower volumes and help protect your hearing.
- TechDefender™: These ear tips include TechDefender™, an acoustically transparent foam that protects your earbuds and in ear monitors from wax, sweat, debris and moisture.
- Tip Lifespan: The lifespan for these tips depends on use and averages 2-3 months per pair. How you use the tips, body chemistry (earwax, oils, etc.), and the environment will affect how long your tips last. Replace when the tips flake, tear or lose memory foam properties such as expanding too quickly. Tips will deteriorate if exposed to alcohol-based cleaners, hand sanitizers or lotions.
Compatible with Beats Powerbeats Pro & Flex, Sennheiser IE 300, Bose QuietComfort 20, Campfire Audio Andromeda, Loop Earplug, Sony IER-M7, Ikko OH10 and more (see compatibility tab.)
