  • ColorBlue

Built for movement

The Beoplay EX Anthracite Oxygen earbuds are true-wireless in-ear headphones with adaptive active noise cancellation and beamforming microphones. An IP57 rating protects the buds against dust and water immersion so they stay reliable during sport, commuting or outdoor work in wet conditions. The aluminium charging case stores enough energy for 20 hours of playback with noise cancellation active.

Consistent output through the day

A single charge of the earbuds lasts through a full working shift while the case tops them up without a cable. Adaptive ANC adjusts to wind and ambient sound in real time instead of relying on a fixed profile, so the isolation level remains steady whether you are on a breezy trail or a busy train. Low-latency audio keeps calls and media in sync during extended sessions.

IP57 decides the use case

The IP57 ingress-protection rating is the single specification that determines whether these earbuds suit your environment. If you need buds that survive sweat, rain or brief submersion during exercise, the rating confirms they are built for it. Buyers who require a higher water-pressure rating or a different form factor will need to look elsewhere.
