This is Suunto’s USB charging cable for its bone conduction headphones — the replacement for the headphone charging cable supplied in the Suunto Wing and Suunto Aqua boxes. The connector mates with the headset’s charging contacts, and a full headphone charge takes an hour or less on Suunto’s published figures.
Charging cables are the first thing to vanish from a swim bag. A spare on the desk or in the travel kit keeps your open-ear headphones ready without rationing the one cable that came in the box.
