Take the Velcro pad that the speaker will attach to, and test for the best position to fix it. The Velcro pad should be attached at ear level in the helmet pocket. You will need to place the helmet on several times to find the optimal position to apply the pad. Once you have found the correct positioning, remove the protective strip and place the pad over the Velcro.3. Then take the in-ear speaker and attach it to the Velcro pad. Run the microphone arm down lengthwise to where your mouth will be. Because the microphone arm is flexible, you can adjust it to be in the optimal position in front of your mouth. Some helmets have removable padding; If so, it is recommended to run the speaker and microphone under the padding.4. Taking care to match the pins, connect the headset plug to the headset jack.
