Replacement Ear Tips for Bose, Sennheiser, and More | Ultimate Comfort & Unshakeable Fit | Small, 3 Pairs

The TOZ-400 is part of our 400 Core Series for wired earbuds and in-ear monitors (IEMs), and features an oval tip shape designed to provide an optimal balance of comfort and stability with minimal preparation required. Most people have an oval-shaped ear canal, and our new oval-shaped tips are engineered to fit naturally, without the need for extensive customization.

To install, simply squish the short side of the tip and place it in your ear. The tips include TechDefender™, an acoustically transparent foam that shields your earbuds and IEMs from wax, sweat, debris, and moisture, helping to protect their performance and longevity.

Not sure which size to choose? For oval tips, we recommend selecting the same silicone tip size you currently use. If you're unsure, the assorted package offers a convenient solution. Alternatively, the VPZ-400 variety pack provides one pair each of the Original, Round 2.0, and Oval tips, all featuring TechDefender™, allowing you to experiment and determine the best fit.

Comply Comfort foam ear tips are designed to maximize earbud comfort and eliminate the pain often caused by silicone tips. The body-heat activated memory foam adapts and molds to the unique contours of your ear, providing a custom fit for hours of comfortable listening.

These memory foam tips are engineered to conform to your ear, providing a better grip than silicone to prevent your earbuds from falling out, whether you're exercising, working, or going about your day.

The heat-activated memory foam expands in your ear, creating a superior seal that reduces distractions and improves noise cancellation, delivering an exceptional audio experience at lower volumes and helping to protect your hearing.

The TOZ-400 and other Comply Foam tips are compatible with a wide range of popular earbuds and IEMs, including Bose Quiet Comfort 20, Sennheiser IE300/IE 40 PRO/IE 400 PRO, Campfire Audio Andromeda, 7Hertz Timeless, NuraLoop, ikko OH10, and TIN HiFi T4, among others. Always check compatibility before purchasing to ensure a proper fit and functionality with your specific device and charging case.

The lifespan of these tips can vary, typically ranging from 2 to 3 months per pair, depending on factors such as usage, body chemistry (earwax, oils, etc.), and environmental conditions. Replace the tips when they start to flake, tear, or lose their memory properties, such as expanding too quickly. Exposure to alcohol-based cleaners, hand sanitizers, or lotions can also accelerate the deterioration of the tips.
