Exclusive Launch Benefits

Built for Deeper, More Peaceful Sleep

A secure ear tip seal and soothing sleep audio work together to help mask ambient noise
and partner snoring, creating a more peaceful sleep environment.

Noise Masking Engineered for Sleep

Snug ear tips muffle ambient sounds while soothing sleep audio masks the rest—softening nighttime noises like AC hums and traffic for a peaceful night.

Adaptive Snore Masking

The smart case detects snoring and signals the earbuds to play adaptive soothing sounds, helping mask disruptions so you can both rest easier and feel closer.

Tailored Comfort

Tailored Comfort,
Even for Side Sleepers

Each earbud combines soft silicone with a 3D-contoured fit that sits flush
in your ear, so you can drift off comfortably, even on your side.

Sits Flush Without Sticking Out

Unlike bulky earbuds that protrude, our ultra-slim design rests flat in your ear to minimize side-sleeping pressure.

Layered Ergonomic Design

Built on global ear data, its layered design features a 20% smaller profile* that curves around key pressure points for lasting comfort.

*Compared to previous-generation earbuds.
