Directional Air Drivers
Two 16mm drivers beam sound into the ear canal while leaving it open, so a podcast sits beside the room instead of sealing it off.

01 — The form
Sculpted from a single billet of titanium.
Most earbuds hide inside your ear. Sonder One sits along it — a slim titanium arc that catches the light like a piece of jewelry. We removed the silicone tip, the seal, the pressure. What’s left weighs less than a coin and disappears within minutes of wearing it.

Vegan microfiber band
Every Launch Edition unit is laser-etched with its batch number and assembled by hand in our Lisbon studio.
02 — The sound
Loud for you. Silent for everyone else.
Open-ear used to mean tinny and leaky. We rebuilt the driver from the air up — beaming sound where it belongs and cancelling what escapes.
Leak-Cancelling Array
Four mics steer a counter-wave at the open edge of the driver. The person next to you hears 9dB less of your music than with any open-ear rival.
Spatial Awareness Mode
Head-tracked audio anchors a call or a track to a fixed point in the room — turn your head and the world stays where it is.
9 dB quieter leak
Measured at 30 cm against the next-best open-ear set, at matched listening volume.
