Key Features

• Fast pairing and app tuning: Fast Pair speeds up initial setup and the Sony | Headphones Connect app lets users fine-tune EQ settings for preferred sound.

Who It's For

The WI-C100 is a solid match for commuters, students and casual listeners who prioritize long battery life and straightforward, app-supported Bluetooth operation. It suits users who want dependable daily headphones with splash resistance and decent sound without complex features or a high price.
