Wired earphones XO EP57 with 3.5 mm jack, black

XO EP57 are wired in-ear earphones with a standard 3.5 mm jack designed for use with devices that provide a headphone socket.

How to use

Insert the 3.5 mm plug fully into the device's headphone socket until it is secure. Place the earpieces gently into the ear canals for a comfortable fit; adjust depth to achieve suitable passive isolation and sound balance. When making calls, use the device's native call controls; if the earphones include an inline microphone or remote, follow the device-specific instructions for answer/end and volume control. After use, wind the cable loosely to avoid tight bends that can stress the conductor or the connector.

Usage recommendations

Store the earphones in a dry place and avoid exposing the cable to excessive heat or sharp bends. Clean the earpiece tips periodically with a dry, soft cloth; do not use liquids that could enter the sound nozzle. If connecting to devices without a 3.5 mm socket, use an appropriate adapter compliant with your device model.
