Premium Foam Earplugs for Sony XM5, XM4, Linkbuds S Comply Premium Foam Earplugs for Sony XM5, XM4, Linkbuds S Size M 3 Pairs

Foam that warms to fit your ear

Comply's heat-activated foam softens and expands with body warmth, sealing the ear canal and helping your Sony earbuds stay put. This 2025 version adds an improved holding device between the foam tip and the earbud. The manufacturer says the ultra-soft foam fits better than silicone.

Fits four Sony true wireless models

The tips are made for Sony True Wireless XM5 and XM4, Linkbuds S and C700N. Once fitted, the seal blocks out background noise passively, whether you are running, training or on a noisy commute. Comply notes the foam was first developed for soldiers and combat pilots.

What comes in the pack

Inside are three pairs of black foam tips in Size M, a cleaning tool and a user manual. The pack weighs around 65 g, the tips are made in the USA, and the manufacturer says the packaging uses less plastic.

How to use

Pull the old tip off the earbud and press a foam tip firmly onto it. Roll or squeeze the foam slightly, place the earbud in your ear and let the foam expand to hold it.
