For optimal audio and microphone performance, ensure the audio jack is fully inserted and test volume levels before calls or recordings. Keep the earphones and cable away from moisture, clean the earbuds regularly with a dry cloth, and store them in a protective case to extend product life. If using on devices without a 3.5 mm jack, use a compatible adapter that supports microphone and inline control functionality.
